Product description
Pleated bag filter cartridges (top loader type) are designed for industrial dust collection systems requiring installation from the clean air side. These filters provide increased filtration area and improved dust handling efficiency compared to traditional filter bags.
Technical overview
Top loader pleated bag filters are cylindrical elements with pleated filter media supported by internal and external metal mesh structures. They are installed from the clean air plenum, allowing simplified maintenance and replacement. Typical lengths range from 600 mm to 2000 mm with multiple diameter configurations.
Operating principle
Dust-laden air flows through the pleated filter media, where particles are retained on the surface and within the media structure. Clean air passes through the filter and exits the system. The pleated configuration increases filtration area, reducing air velocity and improving dust cake formation. Pulse-jet cleaning systems periodically remove accumulated dust, maintaining stable pressure drop.
Material options
