Replacement cartridge filters by OEM part number, machine or size
A cartridge filter is the pleated cylinder that does the work in most cartridge dust collectors, weld-fume extractors and downdraft tables: Donaldson Torit Downflo, DFO, DFT, T-2000 and Easy-Trunk; Camfil Farr Gold Series; Airflow Systems DC, DCH, DCB, PCH, DT, PowerBooth and V-Series; Amtech AT, ATV, AV and ATH; Robovent DFM and Fusion Vortex; Plymovent B and BM Series; Trion CA3000; Filter 1 AC and PFV; FumeVac; Dustcontrol. Rx4CleanAir stocks 39 cartridges across those machines, ships in-stock orders by noon Central the same business day, and shows quantity breaks on every listing.
Genuine Airflow Systems, FumeVac and Dustcontrol cartridges are the OEM parts; the rest are non-OEM replacements built to the original's outside diameter, length, inside diameter, end caps, gasket and media class, and each listing names the OEM part numbers it replaces. OEM names are used for cross-reference only.
Three ways to find the right cartridge
- Part number. It is printed on the end cap or the label of the old cartridge. Search it in the box at the top of the page, or find it in the cross reference below; our listings carry the OEM number and its common suffix variants (-016, -461, -340, -436).
- Machine make and model. The equipment pages list every cartridge a machine takes, including the economy and premium media options for the same slot.
- Measurements. Outside diameter, length and inside diameter, plus the end style and media on the old cartridge. Send those through the chat button or a quote request and we will confirm the match before you order.
Media: which cartridge should you buy?
| Media | Use it for | Typical rating |
|---|---|---|
| 80/20 cellulose-polyester | General dry dust at moderate loads; the economical choice and the standard media in many OEM cartridges | MERV 11 |
| Nanofiber (Ultra-Web-type) | Fine or sticky dust, weld fume and high loads; the dust cake forms on the surface and pulses off, so pressure drop stays low and the cartridge lasts longer | MERV 14–15 |
| Spunbond polyester | Abrasive or high-moisture dust; the media can be washed on units designed for it | MERV 11 |
| Airflow Systems UltraLife, Clean 2 and melt-blown | The factory media for Airflow Systems collectors and fume extractors | MERV 14–15 |
Most cartridges here are fire-retardant (FR) media; the listing says so. Choose FR for metalworking, grinding, welding and anywhere sparks can reach the collector.
End styles
- Open/open (O/O): open at both ends; the cartridge slides over a yoke or sits between two seals.
- Open/closed (O/C): one end capped; the cartridge seats against the tube sheet on its open end.
- Open/closed with bolt (O/CB): the capped end carries a threaded insert for a hold-down bolt.

Frequently asked questions
- How do I identify the cartridge filter my dust collector takes?
- Start with the part number on the end cap or label of the old cartridge and search it at the top of the page; the cross reference on this page lists the OEM numbers each of our cartridges replaces. If the label is gone, measure the outside diameter, the length and the inside diameter, note whether both ends are open or one is capped (and whether the cap has a bolt insert), and send those with the machine model through the chat button. We confirm the match before you order.
- 80/20 or nanofiber: which cartridge should I buy?
- 80/20 cellulose-polyester is the economical choice for general dry dust at moderate loads (MERV 11). Nanofiber media loads on the surface rather than deep in the pleats, so it pulses clean more completely, holds a lower pressure drop and usually lasts longer, and it captures finer dust (MERV 14–15); it is the better buy for weld fume, fine or sticky dust and heavy loads. Choose fire-retardant media for metalworking, grinding or welding. Where we list both for the same slot, either one fits.
- What do open/open, open/closed and "with bolt" mean?
- They describe the end caps. Open/open cartridges are open at both ends and slide over a yoke or sit between two seals. Open/closed cartridges have one capped end and seat on the tube sheet with the open end. "With bolt" means the capped end has a threaded insert for a hold-down bolt. Match the end style of the cartridge you are replacing; the listing and the machine page both state it.
- How often should cartridge filters be replaced?
- Go by the pressure gauge, not the calendar. Pulse cleaning should bring the differential pressure back down after each cycle; when it no longer recovers, or climbs past the collector's rated range, the media is blinded. Torn media, a failed gasket or dust downstream of the filters means replace now. Dust load, pulse settings and humidity set the interval, so two shops with the same collector can be a year apart.
- Are these genuine filters, and how fast do they ship?
- Genuine Airflow Systems, FumeVac and Dustcontrol cartridges are the OEM parts; the rest are non-OEM replacements built to the OEM cartridge's dimensions and media class and covered by our fit guarantee. In-stock orders placed by noon Central ship the same business day: UPS Ground for a few cartridges, LTL freight for pallet quantities, both quoted at checkout before you pay.
