Product description
Pleated bag filter cartridges (bottom loader type) are designed for installation from the dirty air side of dust collection systems. They provide high filtration efficiency and increased surface area within a compact footprint.
Technical overview
Bottom loader pleated bag filters are cylindrical cartridges constructed with pleated filter media and reinforced by metal mesh supports. These filters are installed from below, making them suitable for systems where access is limited to the dirty air chamber. Typical lengths range from 300 mm to 2000 mm. :contentReference[oaicite:2]{index=2}
Operating principle
Air containing particulate matter flows through the pleated media, where dust is captured on the surface and within the fiber matrix. Clean air exits through the inner core. The pleated design increases filtration area, reducing air velocity and improving dust release during pulse-jet cleaning cycles.
Material options
- Cellulose media
- Polyester media
