The ProFi-Clean 90 is a compact de-dusting and filtering device with an automatic blow-back system. It allows the filtering and separation of powder particles in the extracted air.
The de-dusting filter is cleaned automatically by pressure impulses. This guarantees that the whole cartridge surface area remains clog-free and the powder is blown-back into the product. The pneumatic control system is built on the filter housing wherefore the filter device works completely independently. Offering a unique and compact construction, the stand-alone de-dusting filter is easily integrated in existing and new process plants.
