Retrofit Cartridge Filters for Dust Collectors (OEM-Compatible)
If you are looking for replacement cartridge filters for an existing dust collector, APC AirProControl manufactures retrofit cartridge filters that match the dimensions, sealing surfaces, and mounting styles of many popular OEM systems. Our goal is simple: drop-in fit, stable airflow, and long service life—without changing your collector.
CARTEX replacement cartridges are engineered for demanding industrial environments such as welding fumes, powder coating, woodworking, cement, chemicals, food processing, and high-dust production lines.
Retrofit Cartridge Filters We Manufacture
We can produce retrofit filters in different constructions, including:
- DIN Cylindrical Cartridge Filters
- Oval Cartridge Filters
- Square / Rectangular End Cap Cartridge Filters
- Lug & Threaded Cartridge Filters
- Pleated Bag Cartridges (bag-to-cartridge retrofit)
- Flat Cell Filters
(These formats are widely used in dust collectors and industrial extraction systems, so retrofitting is typically straightforward when dimensions are confirmed.)
Designed for Drop-In Replacement
A retrofit filter must seal correctly and clean properly. That’s why we focus on:
- Exact fit: OD/ID, length, bolt patterns, lugs/threads, and end-cap geometry
- Reliable sealing: EPDM / polyurethane gasket options depending on system design
- Pulse-cleaning compatibility: pleat geometry and support structure designed for stable cleaning cycles
Filter Media Options for Your Process
Choose media based on dust type, humidity, temperature, and safety requirements:
- Cellulose / cellulose blend for general industrial dust
- Polyester (spunbond) for tougher service conditions
- PTFE membrane for high efficiency and difficult dust release
- Fiberglass for high temperature / specific industrial needs
- Optional treatments: nano-coated, water-repellent, oil-mist resistant, antistatic / conductive, flame-retardant configurations
Efficiency, Pressure Drop, and Service Life
Our replacement cartridge filters are designed to maintain high filtration efficiency while supporting low pressure drop to reduce fan energy consumption. Many configurations target F9 / ePM1 80% class performance depending on media selection and application.
ATEX / Safety Options for Hazardous Dust
If your facility operates in explosive dust atmospheres (Zone 20/21/22), we offer conductive media and conductive filter body options to support safety-focused filtration designs.
Industries & Applications
Replacement / retrofit cartridge filters are commonly used in:
- Welding, laser & plasma cutting
- Powder coating & surface treatment
- Cement, gypsum, minerals
- Woodworking & furniture
- Food, grain, and packaging dust
- Chemical and pharmaceutical powders
How to Order the Correct Retrofit Cartridge Filter
To manufacture a perfect retrofit match, share any of the following:
- Existing filter brand/model (if known)
- OD / ID / length, end-cap style (open/open, open/closed), gasket position
- Mounting type (thread, lug, flange, snap band, etc.)
- Dust type (sticky, fibrous, oily, humid) + required efficiency
- Any safety requirement (ATEX, antistatic, flame-retardant)
We have replacement filters for many brands.
