Our relationships with our current customers stand as a testimony of this focus in our organization.
Our dust collector filters are carefully fabricated and sized to ensure ease of installation and change-out. These bag filters are designed to be mounted and gasketed firmly into place with a snap band, corded cuff, or clamp to ensure a dust tight seal. Various coatings and finishes (PTFE Membrane) can be applied to either side of the dust collector bag filter to enhance cleaning and efficiencies, as well as to prolong service life. Ground wire, anti-collapse rings, and other options can be easily incorporated into bag construction. For more details and information on how to select a bag filter for your application, see instructions and table below, or click here.
In addition to our own line of bag filters, we also supply high quality OEM and replacement bag filters for:

The top and bottom construction of a bag filter involves a variety of possible configurations. The type of cleaning process used by the dust collector determines which configurations will be used in the design of the bag filter. The way to best determine the construction of the bag that you will be ordering will be to take a sample from the application that you will be replacing.
In a pulse jet (pulsejet or reverse jet) dust collector, you will generally see a double beaded snap ring, or snap band are most common amongst the top configurations. In the bottom configurations, you will typically see a double-beaded snap ring, or a snap band. A shaker dust collector top configuration typically includes a loop top, grommet top, strap or tail top, metal hanger or cap, or snap ring. Shaker bottom configurations will usually be a corded cuff with clamp, double beaded snap ring, or snap band. And finally, in a reverse air dust collector, typical top configurations include cap top with hook, corded cuff with clamp, or snap band; while the typical bottom configurations are snap-band.
Universally, amongst all types of dust collectors, typical top configurations include snap band, raw edge, snap band, loop top, or grommet top; typical bottom configurations include snap band, hem, beaded cuff, over lock disk, and lockstitch disk. The following chart should help to define the above types of configurations:

-
Brand name/ original manufacturer of the original dust collector or baghouse
-
Is it a shaker, reverse air, or pulse jet style dust collector?
-
How does the bag load?
-
Material/Fabric type (Filter Bag Media)
-
Measurements for the diameter (or square) and length of the bag
-
Size of existing cage
-
Top and bottom construction (Also, see our Filter Bag Design Spreadsheet for assistance)
-
Any other special requirements that you might have (groundwire, anti-collapse rings, wearstrip, PTFE Filter Bag Membrane)
To place an order, call a U.S. Air Filtration Parts Specialist at 888-221-0312.

Shaker Dust Collectors (Mechanical Cleaning)
Shaker dust collectors are found generally in business-critical applications where unscheduled down-time will shut down an entire plant. In a shaker cleaning system, the particulate is collected on the inside surface of the bag filter. 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 (or PTFE Membrane) and the fabric, and clean air exits through the outside of the bag. Shaker bag top and bottom designs vary by cleaning system and original equipment manufacturer.
Reverse air dust collectors are found in very large air handling environments such as power and cement plants although they do have uses in a variety of industries. Like the shaker cleaning system, in the reverse air dust collection system, particulate is collected on the inside surface of the bag filter. The particulate is filtered by the dustcake (or PTFE Membrane) and the fabric, and clean air exits through the outside of the bag. Shaker bag top and bottom designs vary by cleaning system and original equipment manufacturer.
Pulse Jet (or Pulsejet) Dust Collectors (Reverse jet)
Pulse Jet (or pulsejet) and plenum pulse dust collectors are found in almost every industrial environment. They are by far the most popular design of dust collector and are seen in nearly all industry segments. Plenum and pulse jet baghouses collect dust on the outside of the bag filter. Dust-laden gas floods the baghouse, and clean air exits through the inside of the bag while the dust particles collect on the outside filter surface. A support cage is used to prevent bag collapse during filtration and aids in the re-distribution and cleaning of the dustcake. A wide variety of bag filters can be manufactured to meet specific application needs.
Bag filters may load into a dust collector (shaker, plenum, pulse-jet or reverse air) from the top of the machine, bottom of the machine, or side of the machine. System engineer will be able to provide this information to ordering representative.
Measurement of the existing filter bag / bag filter is crucial to your order. You may send your used bag filter to your U.S. Air Filtration representative for their measurement in order to avoid any mistakes. Or, you may provide measurements to us for an order yourslf.
Keep in mind that original equipment manufacturer configurations may not still be applicable to your particular application. Most dust collectors have been upgraded over the years due to the need for new permits which called for reconfiguration of the baghouse. Because of this, you will need to obtain accurate measurements of one of your current bag or cartridge filters prior to ordering replacement filter bags / bag filters. A spare bag that has not been used yet can be measured if available. If you currently have bag filters that are functioning properly, you can pull out one of these bags to get the proper measurements for your replacement order. (Please be sure to use all necessary precautionary measures set in place prior to removal i.e. gloves, protective garments, and respiratory equipment if needed). It is not best to pull the numbers off of the unit because possible changes to the configurations. The best solution is to mail U.S. Air Filtration representative a new or used bag filter that can be used as a guide sample.
Your particular application may requre special options in order to perform its proper function. Some of these options may include:
Ground wires- used to comply with factory mutual requirements for static dissipation Ground wire may be made from stainless steel or copper. However, this technique only works on a localized area of a filter. For optimal static dissipation, look at conductive fiber bag filter media made with Epitropic or Stainless Steel fibers.
Wear Cuffs- Used to combat abrasion at the bottom of the bag, either from the "sandblasting" of the bag filters or bag-to-bag abrasion due to turbulence in the baghouse. Usually 2 to 4 inches in length and made of a material similar to that of the body of the bag filter.
Special Finishes- There are many finish options that we can add to the filter media at the time of manufacturing. (PTFE Filter Bag Membrane, etc...) Please refer to our bag filter media page for further details.
