Variable round filter series as cartridge filter


The INFA-MINI-JET familiy is a versatile circular filter program. Customer-specific designs are available due to individual constructions. Because of an optional hot gas design, pressure resistance and gas-tightness, the fully automated cartridge filters ensure the separation of dust and powder products as well from exhaust air as from process gases.

During the filtration phase the cleaning of the filter cartridges is done in periodic intervals by pulses of compressed air (jet-pulse cleaning). The cartridge filter sizes cover a volume flow of 20 m³/h to 12,000 m³/h. 

Standard design features
