Request a QuoteThe filter replaces fabric bags with a single‑piece pleated metal cartridge that fits standard dust collector housings.
Sourcing directly from the factory eliminates intermediate handling and provides buyers with exact design data for system integration.
Manufacturers typically form the cartridge by pleating a continuous metal sheet into a cylindrical shape, creating a high surface‑area filtration media.
The pleats are supported by a perforated stainless steel core that prevents collapse under differential pressure while allowing uniform airflow.
End caps are welded or mechanically crimped to the media, and a nitrile or EPDM gasket provides a seal against the housing, ensuring bypass‑free operation.
| Parameter | Typical Value | Notes |
|---|---|---|
| Filtration efficiency (0.5 µm) | ≥99.9 % | Measured per ISO 12103‑1 test dust |
| Initial pressure drop | 150 Pa at 0.5 m/s face velocity | Dependent on pleat height and media thickness |
| Maximum operating temperature | 350 °C (SS 316L) | Limited by gasket material; higher temps require metal seals |
| Cartridge outer diameter | 140 mm (standard) | Custom diameters from 100 mm to 200 mm available |
| Effective length | 500 mm – 1000 mm (standard) | Length adjustable in 50 mm increments |
| Media thickness | 0.20 mm (±0.02 mm) | Affects strength and pressure drop |
In metalworking shops, the filter handles hot swarf and oxide particles that would degrade fabric bags.

Woodworking facilities use it to capture fine sawdust at elevated temperatures generated by sanding belts.
Pharmaceutical and chemical plants select the stainless steel version for its compatibility with solvent vapors and ease of cleaning.
Each cartridge undergoes dimensional verification of pleat height, diameter, and length using calibrated gauges.
Airflow resistance is measured at multiple flow rates to confirm compliance with the specified pressure‑drop curve.
Material certificates are retained for all metal coils, and a bubble‑point test validates media integrity before shipment.
| Feature | Standard (SS 304) | High‑Temp (SS 316L + metal seal) |
|---|---|---|
| Max temperature | 260 °C | 350 °C |
| Gasket type | Nitrile | Metal O‑ring |
| Typical pressure drop @ 0.5 m/s | 150 Pa | 180 Pa (slightly higher due to seal) |
| Recommended industries | General wood, light metal | Foundry, chemical, pharma |
Can the cartridge dimensions be customized? Yes, diameter, length, and pleat height can be adjusted to match specific housing designs; provide your mounting drawings for a quote.
What information is required before quotation? Required data include airflow volume, operating temperature, dust characteristics, and any special material or coating preferences.
What is the typical production lead time? Standard lead time is 3–4 weeks after drawing approval; expedited options are available upon request.
