Replacement Cartridges

OEM Replacement Cartridge Filters

We supply replacement cartridge filter elements for dust collectors and build them to the OEM specification or higher from quality components. We can cross-reference virtually any cartridge or modify a design to solve a specific problem, such as short filter life, high pressure drop or a hard-to-release dust.

Cartridge filters pack a very large filter surface area into a compact package, which makes them especially effective in air filtration applications with limited space: weld fume and grinding dust, powder coating booths, pharmaceutical and food powders, and fine industrial dust.

How They Work

How Dust Collector Cartridges Work

Dust-laden air enters the collector and passes from the outside of the cartridge to the inside. Particles collect on the face of the pleated media and build a thin dust cake, and clean air exits through the open end cap to the clean-air plenum. A pulse-jet system fires short bursts of compressed air back through each cartridge to knock the cake loose so it falls to the hopper.

Differential pressure across the filters is the best health check. When it stays high after cleaning, airflow at your hoods drops and the cartridges are loaded, blinded or near the end of their life. Our troubleshooting guide and maintenance checklist cover the common causes.

Warning Signs

Signs It Is Time to Replace Cartridges

  • Differential pressure stays high after pulse cleaning

  • Weak suction or lower airflow at pickup points

  • Visible dust at the clean-air outlet or stack

  • Torn, caked or blinded pleats

  • Shorter run time between cleaning cycles

Filter Media

Choosing Cartridge Filter Media

The right media depends on particle size, moisture, temperature and whether your dust is sticky or combustible. These are the most common cartridge media types. Tell us what you collect and we will recommend the media for your replacement.

Learn more in which fabric filter media is best or browse our filter media.

Cartridge Media Best For
Cellulose blend General dry dust in lighter-duty, low-moisture applications
Spunbond polyester Durable, moisture-tolerant media that releases dust cake well
Nanofiber surface layer Fine weld fume and sub-micron particulate with surface loading
PTFE membrane Sticky, fine or hard-to-release dust and high-efficiency needs
Anti-static media Combustible or static-prone powders such as flour, sugar and plastics
Pleated Baghouse Bags

Pleated Filter Bags for Pulse-Jet Collectors

Pleated filters replace traditional filter bag and cage configurations in pulse-jet dust collectors. They can offer two to three times the filter area of a standard bag, which lowers the air-to-cloth ratio, and they are shorter than a typical bag, so you use less compressed air when pulsing. The shorter length also opens up more drop-out area below the filters.

We offer many options for media, pleat count and construction, and we can help convert your existing baghouse bag and cage setup or quote replacements for what you use now.

Less compressed air per pulse

Intake air filters for blowers and compressors
Intake Filters

Intake Filters for Blowers and Compressors

Blowers and compressors are built with very tight tolerances between their internal parts. Airborne dust wears those parts, lowers efficiency and leads to unplanned downtime. Our intake air filters protect that equipment, especially in dirty or dusty environments.

We use a wide range of filtration media, including paper, felt, wire mesh and polyurethane, in disposable or washable, reusable styles built to an OEM fit.

Turbine Filters

Gas Turbine and Compressor Intake Filters

We supply high-efficiency intake filters for industrial rotating equipment such as gas turbines and centrifugal compressors. Modern turbines are extremely sensitive to particulate in the combustion air, and the right filter keeps downtime to a minimum and the turbine running efficiently.

Gas turbines run everywhere from remote, extreme sites to plants near city centers, so we match the filter style to your site conditions.

Overbags That Extend Cartridge Life

Overbags slip over a cartridge filter or pleated bag to stop dust from bridging across the pleats. In the right applications they extend the life of the filter underneath.

We keep a wide range of materials in stock and custom make overbags to fit your filter.

FAQs

Cartridge Filter Questions

Have a part number or a filter that keeps failing early? Our team can help you spec the right replacement.

A cartridge filter is a cylindrical filter element made from pleated media wrapped around a support core and sealed between two end caps. The pleats pack a very large filter surface area into a compact package, which is why cartridge-style dust collectors fit where a bag house will not.

The fastest way is to send us the OEM part number or the make and model of your dust collector, and we will cross-reference it. Without a part number, give us the outer diameter, inner diameter, overall length, end cap style (open, closed, flange, bolt hole or twist-lock), gasket type and the media on your current cartridge.

We manufacture replacement cartridges for most OEM dust collectors, including Donaldson Torit, Camfil APC, Farr, RoboVent, Lincoln Electric, Plymovent, Nordson and many more. Our replacements are built to the OEM specification or higher, and we can modify a design to solve a specific problem.

Cartridges use pleated media to fit more filter area into less space and work well for fine, dry dust such as weld fume, powder coating overspray and pharmaceutical powders. Filter bags handle heavier dust loads, larger particles and high-volume collection. Pleated baghouse bags sit in between, adding surface area to an existing bag house.

Cartridge life depends on the dust, the airflow and how well the pulse cleaning works. Plan a replacement when differential pressure stays high after cleaning, airflow at the hoods drops, dust shows at the clean-air outlet, or the media is torn, caked or blinded.

Most pleated dust collector cartridges are cleaned in place by pulse-jet and are not designed to be washed. Water can damage cellulose-blend media and trap moisture in the pleats. Some intake filters are made to be washable and reusable, so ask us which style fits your equipment.

Yes. Pleated bags can offer two to three times the filter area of a standard bag and are shorter, so they use less compressed air when pulsing. We can help convert an existing bag and cage setup or quote replacements for the pleated filters you use now.
