Features
The patented Multicell filter cartridge is design-ed for compact dust collectors. Only one cart-ridge per filter is needed for an air volume of up to 2500 m³/h. According to the air volume more cartridges can be added.
The Multicell filter cartridge consists of two coni-
cal shaped cartridges integrated into each other which use as well the empty inside cavity as filter surface.
The raw gas flows through the cartridge from inside and outside at the same time. The puri-
fied air escapes to the top. The Multicell filter cartridge is divided into two cells. Both cells are cleaned alternately by jet pulses without inter-
rupting the filtration process. The conical shape makes cleaning more effective. The compressed air flows in through an annular nozzle. The maximum operating temperature of the Multicell filter cartridge is 80 °C. Models for higher temperatures, with metal parts of stainless steel or FDA-approved versions are available on request. The Multicell filter cartridge is installed from the raw gas side or the clean side.

Filter Media
The pleated filter media consist of polyester or polypropylene non wovens or needle felts. They can be equipped antistatic, oil and water repellent, with special coatings or mem-branes. They are certified in accordance with DIN EN 60335-2-69 appendix AA and are suitable for the filtration of health hazardous dusts.
The filter medium is adjusted to the application in order to provide optimum performance in filtration.
