What is a Cartridge?
Cartridges are designed to collect dust inside the Silo Filter. The Filter Cartridge keeps the ambient air clean by preventing the spread of dust that may escape during the filling of dry powder or granular materials into closed storage areas such as silos and bunkers.
Circular (Oval-Cylindrical) Type Filter Cartridge and Rectangular Type Cartridge
One of the greatest advantages of these types of cartridges is the ease of assembly and disassembly. Cartridges can be easily removed by unscrewing three bolts. Due to the pleated manufacturing structure of the cartridges, they provide a larger filtration area within a smaller diameter.
