As factories and industrial plants resume production after a shut-down period, employers are faced with the responsibility of minimizing work hazards by instituting best practices and safety measures. This is where a dust collection start-up guide will help.

Starting up your dust collection system the right way will make sure your equipment is operating properly while also protecting the safety of your workplace and workforce. The steps in this dust collection start-up guide will also ensure your system is in good working order so you don’t have to worry about an unexpected shutdown.

To streamline your start up process and make it as hassle-free as possible, we’ve prepared a comprehensive checklist and action item notebook. These resources can help you address any issues promptly. Our guide is broken out into four sections:

  1. Best Practices for Dust Collection Start-Up
  2. Dust Collector Start-up Checklist
  3. Action Item Checklist
  4. Maintenance Questions to Consider

Part 1: Best Practices for Dust Collection Start-Up

Power Down & Lock Out

Before you begin start-up, maintenance or troubleshooting on your dust collection system, your first and most important step is to power down and lockout any machinery. Securing your baghouse for personnel entry can include locking down your rotary valve, locking your blower, or sealing off any adjacent baghouse compartments. Taking these initial steps provides a safe working environment and will
ensure that accidents are minimal.

Additional Watchman & Communication Plan

Designate an additional crew member as a watchman. They should be present to ensure safety procedures are being followed and can immediately assist should any complications occur. It’s important to let your team know what work is being done, where, and at what time. This allows others to re-schedule any work that could impede on a safe start-up of your dust collection system.

Combustible Dust

If you are working with combustible dust, make sure the dust levels inside of your system are well below being explosive. Perform all hot work, like welding, well outside of the perimeter of your dust collector.

Emergency Plan

A total shut down and lock out of your dust collector will minimize safety hazards, but you shouldn’t hesitate to formulate a retrieval plan should an emergency occur.

PPE (Personal Protective Equipment)

OSHA requirements for protective gear will vary based on your application. Basic protection can include a hard hat, safety glasses, gloves, and a face mask. Before start-up or entry into your baghouse system, make sure that your crew is supplied with and compliant in wearing safety gear required for your application.

Choosing the right filter bags for your dust collection system is critical to ensuring long term, reliable performance of your collector and the safety of your employees. Our guide will help you understand your facility’s unique dust properties and provide an overview of various filter media, construction, and treatment options available.

We’ve organized our dust collector filter bags guide into these key topics:

Top Factors to Consider for Dust Collector Filter Bags

  2. Dust Testing
  3. Common Filter Media
  4. Filter Bag Finishes
  5. Filter Bag Construction
  6. Air-to-Cloth Ratio
  7. Additional Resources

Understanding Dust Properties

Choosing the right filter media for your dust collection system is critical to achieving peak performance while reducing system wear, plant downtime, and extending filter life. The first step is to consider the properties of your dust particulate and review the following:

  • Product – What  you  are filtering?  Does your product contain a moisture or oil? Products with moisture content greater than 25% are not suited for a dry dust collection system (baghouse, cartridge collector or bin vent). Products containing hydrocarbons, including oils, may require the application of special treatment to your filter media for optimal
  • Temperature – What is your typical operating temperature? Max temp? Media temperature ranges for dry dust collection can typically be sorted into three categories listed below:
    • < 275°F – Polyester filter media performs very well for ambient airflow temperatures in this range.
    • Between 275°F and 400°F – Aramid filter media is the optimal choice for temperatures in this
    • Between 400°F – 500°F – Fiberglass filter media is the most economical option for high-temperature applications; however  depending  on the type of dust, another filter media may be a better

Once you understand the temperature of your work environment, you can narrow down your filter media options and in many cases, apply a special treatment to the media to further improve performance. Treatment application can be an efficient way to minimize costs before considering a more expensive filter media.


Does the airstream or dust contain chemicals that could damage the filter media? Are their acids or alkalines in the airstream? Often when certain compounds are combined during processing, a chemical reaction can occur, which may require a specific media treatment or coating on your filter bags to protect the bags from accelerated wear.


How abrasive is the dust being filtered? Consider the hardness of the material that’s being filtered along with the shape of the dust. The velocity of your airflow can also make your dust more abrasive. If you are designing a new dust collection system, it’s important to engineer the ductwork, fan size, and unit placement to ensure the airstream is not entering your dust collector too quickly or too slowly.

Particle Size

What size dust particulate are you collecting? Depending on your emissions requirements, your application may require a special membrane. This will apply if your particulate is very fine.

Is Your Dust Combustible?

Combustible dust can be defined as any fine material that has the ability to catch fire and explode when mixed with the proper concentration of air. Examples of combustible dust include wood , food products such as grain, sugar, flour, starch, metals, rubber, chemicals, pesticides, plastics, and more. To protect your plant and your employees from the risks of a serious explosion, carefully consider OSHA and NFPA guidelines and be sure to review your state and local regulations for proper identification and management of combustible dust.

OSHA Standards

Implement and maintain OSHA’s set of standards regarding combustible dust. When you adhere to OSHA’s set of standards, you are creating a safe work environment, avoiding property and economic loss from an explosion, and avoiding regulatory fines.

NFPA Guidelines

Make sure you are meeting codes outlined by the NFPA (National Fire Protection Agency) . The NFPA publishes a list of guidelines that will help you minimize injury or death from combustible dust. The following regulatory codes are related to the most combustible types of dust (e.g., sugar, wood , fine aluminum):

  • 664, Standard  for the Prevention of Fires and Explosions in Wood Processing and Woodworking Facilities
  • 484, Standard for Combustible Metals
  • 61, Standard for the Prevention of Fires and Dust Explosions in Agricultural and Food Processing Facilities

Dust Testing

Dust testing may also be performed to assess the properties of your particulate and ensure proper filter selection and performance. This option may be ideal for new facilities and large applications . If you have an existing plant and many of your filter bags have failed prematurely with no consistent pattern, and there are no signs of workmanship  error, it  may be necessary to perform laboratory testing to find out if changes in the airstream could be compromising the bags.

Common Filter Media


Polyester media is an economical option with excellent filtration properties and is widely available. This makes polyester the most common filter media used across many industry applications. Polyester has an operating temperature limit of 275°F and comes in both needled felt and woven medias. Both needled felt and woven polyester  can  be treated with several finishes and membranes  to  increase the efficiency and filter bag performance in varying operating conditions.


Aramid, also known as Nomex, is used in applications with high temperatures and has excellent filtration and abrasion properties. The operating temperature limit for aramid is 400F which makes it a  great choice for applications such as asphalt batch plants, furnaces, and dryers. Both needled felt and woven aramid can be treated with several finishes and membranes to increase the efficiency and filter bag performance in varying operating conditions.


Fiberglass is often used in baghouses with temperatures ranging up to 500°F. Since fiberglass media is typically woven, the efficiency of a plain fiberglass media is lower than most felts. However there are several different membranes and finishes that can be added to fiberglass to increase filter efficiency and performance in harsh baghouse conditions. These finishes and membranes make fiberglass a versatile media for  applications  with high temperatures. You’ll see  Fiberglass  media used in industries such as energy, cement/ concrete/aggregates, and agriculture. Different membranes, coatings and finishes can be added to fiberglass media to increase performance in certain applications. This makes fiberglass a versatile media for applications with high temperatures.


P84 media has a high temperature rating of up to 500°F. This filter media handles acids better than fiberglass and also results in less abrasion to the filters due to filter media flex.

Teflon (PTFE)

Teflon (PTFE) is one of the highest performing filter medias available for  a wide range of applications and is also the most expensive. It bears well against chemical and acid resistance, high temperatures, and moist heat. Teflon membrane can also be applied as a treatment on other filter medias to further extend filter life and reduce system wear.

For more information on other media types in the dust collector industry (e.g. PPS, Acrylic, and Polypropylene) access our Fabric Characteristics Chart below.

Filter Bag Finishes

Benefits of Filter Bag Finishes

  • Lengthen the life of your filter bag
  • Better dust cake release (reduced valve pulsing = reduced compressed air consumption)
  • Achieve more consistent airflow
  • Reduces downtime and maintenance

Filter media fabrics can be made from both natural and synthetic fibers, although synthetic fibers are more common today. As we have seen in the previous section, different fibers provide each media with different  performance  characteristics. Most medias today are pre-shrunk and include  some type of finish to improve media performance.  Finishes for felt and woven bags can be different as we will see below.


This process is the scraping  of  the  filter  surface  across  metal points  or burrs on a revolving cylinder. Napping raises  the  surface  fibers,  creating  a  “fuzz”, that provides a large number of sites for particle collection by interception and diffusion. Fabrics used for collecting  sticky or oily dusts are sometimes  napped so they can provide better collection and an easier cleaning process.


Coatings , or resin treating , involves  immersing the filter  material in a resin which can add certain characteristics to the filter media. For  example,  fiberglass threads can be coated with Teflon to prevent abrasion during bag cleaning and silicon graphite to aid in acid resistance.

Filter Bag Construction

The construction of your filter bags is dependent on your baghouse style, application, and other requirements specific to your facility. Below is a brief summary of how each type of baghouse works.

The three main baghouse styles available include:

  • Pulse jet
  • Reverse air
  • Shaker

In each baghouse style there are a variety of filter top and bottom configurations that can be used. Some top and bottom configurations are meant for a specific baghouse style, and other configurations can be used across multiple baghouse styles.

Pulse Jet

Pulse jet baghouses collect dust on the outside of the filter and clean filters from the inside out with a jet or pulse of clean air. Dirty air enters the baghouse and is forced to pass through the filter bags to exit the baghouse. As air pass through the bags, dust is filtered out and collects on the outside surface of the filter bags. This buildup of dust on the outside of the filters is known as a “filter cake.” The filter cake aids in filtration by trapping smaller particles as the dirty air passes through the filter cake and bag. Pulse jet baghouses offer a wide range of filter media, making it an excellent fit for most applications.

Reverse-Air or Shaker

In a baghouse using reverse air or shaker cleaning systems, the particulate is collected on the inside surface of the bag. The dust-laden gas enters the dirty side (inlet) of  the  collector  and  flows up through the bag. The particulate is filtered by the dustcake and the fabric, and clean air exits through  the outside of the  bag.  Shaker and reverse  air bag top and bottom designs vary by cleaning system and original equipment manufacturer.

Reverse air and shaker style baghouse both collect dust on the inside of the filter bag. Reverse air baghouses reverse the flow of air through the baghouse in order to clean the filter bags while  shaker style baghouses clean the filter bags by moving them back and forth in a shaking motion. The buildup of a filter cake is important with these style collectors as it greatly aids in filter efficiency.

Both pulse jet and reverse air/shaker style baghouse come in a number of different bag constructions and understanding the requirements of your specific baghouse is important to ensure proper filter bag fit.

Air-to-Cloth Ratio

Dust collector air-to-cloth ratio is a critical measure to ensure your collector is performing efficiently.

Air-to-cloth ratio, also known as air to media ratio, is a measurement of the number of cubic feet per minute of air passing through one square foot of filter media.

Generally, a lower air-to-cloth ratio, the more effective your system is at removing dust from the work environment. When determining an appropriate air-to-cloth ratio, there are several factors to consider, including application, type of dust, moisture levels, inlet loading, etc. If the air-to-cloth ratio is higher than recommended, some common issues can arise, including increased differential pressure, frequent filter changeouts, and varying or reduced suction at pickup points. These issues are a result of not having enough filter media to handle the air flow and dust load effectively. As the dust cake builds on the filters, the airflow is restricted and slows, resulting in a decrease in air velocity and suction. From there it becomes a domino effect: air quality decreases, filters clog quicker requiring more changeouts, pulse valves see increased wear, and facility production may be impacted.

Why is the right Air-to-Cloth ratio important?

  • Ensures dust collector is running efficiently
  • Minimizes operating costs
  • Maximizes filter life
  • To meet air quality goals and requirements

What are the negative effects of an improper Air-to-Cloth ratio?

  • Increases maintenance which can impact production
  • Reduced air velocity resulting in poor ventilation at pickup points
  • Increased compressed air consumption
  • High differential pressure and increased system wear

Our dust collector purchasing guide will help you identify the right dust collection system that will perform safely, efficiently, and reliably for many years to come. Identifying the right components and needs for your next dust collector can be an overwhelming process. Factors to consider include:

5 Things to Consider When Purchasing a Dust Collector

  1. Dust Properties – Learn the dust properties you need to be aware of to help you find the right filter media and type of dust collector.
  2. Volume – Understand key variables for measuring volume or airflow requirements in your work environment in order to size your collector properly.
  3. Air-to-Cloth Ratio – Learn why air to cloth ratio is important and how to find the right air-to-cloth ratio for your operation.
  4. Dust Collector Styles – Learn about three most common dust collectors, their advantages and disadvantages.
  5. Low Maintenance Design Features – Learn important dust collector design features that will help you save time and money in long term maintenance expenses.

At the end of this dust collector purchasing guide, there are also additional resources that provide more details about combustible dust considerations and on demand cleaning.

Dust Properties and Your Work Environment

Do you know your dust? Consider your dust properties and characteristics of your work environment carefully to identify the best dust collection solution.

Dust Properties to Consider:

  • Size – What is the size of the dust particles being filtered; fine or large?
  • Density – Is the dust low in density like wood dust or heavy in density like fine steel dust?
  • Chemistry – Will you be filtering any abrasive dust? Corrosive dust?
  • Temperature – Are you operating in a high heat environment? What is the operating or maximum temperature at your facility?
  • Moisture – Is moisture or oil present in the dust?

Knowing your dust properties is the first step to help you determine the type of dust collector that is best suited for your unique application.

Your Work Environment

The next step to finding the right dust collection solution is to consider your space constraints, emissions requirements and temperature of your airstream.

Space Constraints

Dust collectors vary in height, width and depth depending on the application and the amount of dust being captured. Take note of any height or space restrictions in the work environment and take measurements of the space allotted for your collector along with the space available around the collector. Many dust collectors are top load which means you will need to allow space above the collector to replace and service the collector from the top of the unit.

Emissions Requirements

Depending on your application, your dust collector may require a permit with specific emissions requirements. These emissions requirements vary by state and are expressed as an efficiency percentage for cartridge collectors or an emission limit (e.g. lbs/hr or gr/dscf) for baghouses.

Temperature of the Environment

The temperature of the airstream will determine what type of filter media is required and will affect fan size. Temperatures greater than 260 degrees will require special filter media and changes to the dust collector fan. If the unit will be outside in a cold/extreme climate you will need to consider insulating the unit as well.

Understanding Volume or Airflow Requirements

Calculating Your Airflow

After considering your dust properties, the next step in dust collector purchasing is our airflow or volume requirements. Calculating your airflow correctly is critical to the long term health of your collector so your system will be efficient at capturing dust.

Why is Volume Important?

If the volume of the system is too low, your system will not capture the dust effectively which can impact production and air quality. If the volume of your system is too high, your energy consumption costs will be higher and you may disrupt the process of your application.

How is Volume (Cubic Feet Per Minute) Measured?

Dust collector volume is measured in cubic feet per minute or CFM. CFM is a measurement of airflow especially related to air conditioning, heating and ventilation environments like those requiring dust collection. In dust collector applications CFM measures the amount of air per minute that can be moved from a space.

Variables to Consider

Work environments vary dramatically from one another based on several variables, and even very similar environments can require vastly different volume. To determine the right volume capabilities for your new dust collector, consider some of the following variables carefully.

  • How are you collecting dust?
  • What is the size of the duct being used to collect the dust?
  • Cubic feet of the work environment


Dust collector air-to-cloth ratio is a critical measure to ensure your air filtration system is performing efficiently.

What is Air-to-Cloth Ratio?

Air-to-cloth ratio, also known as air-to-media, is defined as a measurement of the amount of air passing through one square foot of filler media. Generally the lower your air-to-cloth ratio, the more effectively your system removes dust from the work environment. If you are operating at a higher air-to-cloth ratio, one of the common issues you may encounter is a decrease in suction. This is because a large amount of dust laden air is filtered by an insufficient amount of filter media. The dust cake on the bag builds up too quickly; resulting in a decrease in air flow through the filters and suction at pickup points.

How to Select or Calculate Air-to-Cloth Ratio

If you’re sizing a new cartridge collector system and know what type of dust will be filtered and the air volume needed to properly ventilate the area or pickup points. Our Air-to-Cloth Guide below is a good place to start. The guide gives you a general recommendation on the air-to-cloth ratio for several different applications. To find the dust collector suited to your dust and air volume requirements simply:

  1. Divide air volume of system by air-to-cloth ratio to get the total amount of filter area needed into the system.
  2. Divide the total filter area by the filter area per filter to determine how many filters are needed in the dust collector.
  3. Find the dust collector model that best fits your application by number of filters
    and type of dust collector.

To calculate air-to-cloth ratio in your existing system, calculate the volume of air (CFM) and divide that number by the total filter area within your dust collector. For example, a sixteen filter cartridge collector pulling 7,000 CFM would have a 3.65:1 airto-cloth ratio (7000 CFM / 16 filters x 120 ft2 per filter). Or in the case of a baghouse, a hundred filter baghouse pulling 10,000 CFM would have a 6.37:1 air-to-cloth ratio (10,000 CFM / 100 filters x 15.70 ft2 per filter). Environments with a large ventilation area or more pick up points require a higher air volume (CFM) to provide adequate suction which means more filter media to keep a similar air-to-cloth ratio.

Why is selecting the right Air-to-Cloth ratio important?

  • Extends filter life
  • Minimizes your operating costs
  • Meets air quality goals and requirements
  • Allows your dust collection system to perform at peak efficiency

What are the negative effects of improper Air-to-Cloth ratio?

  • Poor venting which causes damage to equipment
  • High pressure drops in differential pressure
  • Impacts your air velocity
  • Excessive use of compressed air

Dangers of an Undersized Dust Collector

Choosing a collector that is too small can cost you in long term maintenance costs. Some of the biggest problems we see people run into with an inappropriately sized dust collector are:

  • Consistently clogged filters (reduced filter life)
  • Increased downtime
  • Higher maintenance and energy costs
  • Decreased efficiency
  • Increased compressed air consumption

To avoid the dangers of an undersized dust collector consider both CFM and air-to-cloth ratio carefully when designing your new unit.

Dust Collector Styles

Baghouse Styles

Baghouses are ideally suited for large volume applications with airflow exceeding 1,000 CFM or when high temperature applications are above 375 degrees. In these environments, a baghouse will handle and most efficiently filter your dust laden air. There are several types or styles of baghouses available. Once you understand your dust properties, volume, and air-to-cloth ratio, you can determine the right baghouse style for your facility. Here is a summary of the pros and cons of the three most common baghouse styles: pulse jet baghouse, reverse air, or shaker style.

Pulse Jet Baghouse

ProsCons Bags cleaned continuously while unit is in operationRequires compressed air Easy to maintain, low maintenance costNot ideal for high moisture applications (+20%) Flexible Sizing and ConfigurationRequires filter cages

Reverse Air Baghouse

ProsCons Low maintenanceNeeds to be cleaned often Gentle cleaning which allows for longer bag lifeResidual dust build up is hard to remove Units are typically compartmentalized into sections which allows them to be maintained without shutting down the entire baghouseFilter bags are expensive compared to Pulse Jet bags Bags are typically custom made and not available in stock for quick shipment

Shaker Baghouse

ProsCons Very simple to operateLimited filter media options Low initial investment costNot space efficient (takes up a large area) Filters cleaned via shaker mechanismNot suited for high dust loads Bags are typically custom made and not available in stock for quick shipment

What’s the Right Type of Pulse Jet Dust Collector?

The three most common pulse jet dust collection systems are baghouses, cartridge collectors, and bin vents. Below is an overview of each type of pulse jet system and common applications for each:


Baghouses are typically the largest of the three types of dust collectors. They are well suited for large volume and high temperature applications. Baghouses are perform well for applications with high dust loads of more one 55 gallon a drum per day. The most common applications that use baghouses include:

  • Wood
  • Mining
  • Asphalt
  • Foundries
  • Cement

Cartridge Collector

Cartridge Dust Collectors are compact and very modular in design. These are best suited for applications with the following characteristics:

  • Moderate or low dust (collecting less than one 55 gallon drum per day)
  • High efficiency filtration requirements
  • Space restraints or small footprint requirements
  • Possibility of future plant expansion

The most common applications for cartridge collectors include:

  • Welding
  • Grinding
  • Laser/Plasma Cutting
  • Bulk Powder Processing

Listed here is a baghouse and cartridge collector comparison chart to help you determine which option may be best suited for your application.

How to Prevent a Dust Collector Explosion

If you are dealing with combustible dust, you’ll need to implement a preventive maintenance plan, which will help you avoid a serious dust collector emergency.

What is combustible dust?

Combustible dust can be defined as any fine material that has the ability to catch fire and explode when it’s mixed with the proper concentration of air.

When can combustible dust create an explosion?

When the right conditions are in place, combustible dust can become hazardous and create an
explosion. Dust can collect on multiple surfaces in a facility (e.g. ducts, crevices, dust collectors, equipment, etc.), and once this buildup of dust mixes with the right conditions, it only takes a small ignition source to create a significant explosion. There are even scenarios in which combustible dust can self-ignite. This usually results from static that builds up as the particulates rub against one another.

Who does it affect?

Combustible dust effects a wide variety of industries such agriculture, metalworking, mining, chemicals, plastics, pharmaceuticals, etc. Industries that are susceptible to combustible dust are regulated by OSHA standards and NFPA guidelines.

How can I prevent a dust collector fire?

Now that you know what conditions required for combustible dust, when it can happen, and who it effects, how do you limit or prevent a serious explosion from happening? Your best plan of action is going to include steps that are proactive instead of reactive. Here are the proactive steps you can take:

  • OSHA Standards: Ensure you are meeting OSHA’s set of standards regarding
    combustible dust. Industries that are susceptible to combustible dust are regulated
    by OSHA standards when you implement OSHA’s set of standards, you are
    creating a safe working environment, avoiding property and economic loss from an
    explosion, and avoiding regulatory fines.
  • NFPA Guidelines: Make sure you are meeting codes outlined by the NFPA
    (National Fire Protection Agency). The NFPA publishes a list of guidelines that will
    help you minimize injury or death from combustible dust. The following codes are
    related to the most combustible types of dust (e.g. sugar, wood, fine aluminum):
    • 664, Standard for the Prevention of Fires and Explosions in Wood Processing and
      Woodworking Facilities
    • 484, Standard for Combustible Metals
    • 61, Standard for the Prevention of Fires and Dust Explosions in Agricultural and
      Food Processing Facilities
  • Preventative Maintenance Plan: Properly maintain your facility and dust collector
    to help prevent a buildup of dust. Clean up any excess dust build up on your dust
    collector, other equipment, vents, and filters.
  • Explosion Vents: Installing an explosion vent on your dust collector is one strategy
    that can minimize damage to your equipment and harm to employees should an
    explosion happen. The purpose is to relieve pressure in the dust collector caused
    by an explosion. Once the activation pressure is exceeded the vent(s) open safely
    relieving pressure.
  • Explosion Latches: Latches operate under the same concept as explosion vents.

Selecting and pricing out a dust collection system involves careful consideration of each of the variables outlined above. Proper attention to these items is critical to ensuring your dust collector performs efficiently for many years to come and creates a clean, safe work environment for plant operators.

To help you engineer and select the correct system for your facility, consult with a dust collection engineering and manufacturing company with extensive experience designing systems for diverse applications.
