Title: PLEATED MULTILAYER FILTER FOR PULSED OPERATION
Abstract:
The invention relates to a pulse filter (100; 110) having two stage filters (101, 102; 113, 114), each having filtering properties different from each other. The first stage filter (101; 113), through which the fluid flow to be cleaned passes first, is arranged to filter coarser materials and the second stage filter (102; 114) is arranged to filter finer substance from the fluid flow. The first (101; 113) and second stage filter (102; 114) are formed as separate pleated structures, which are optionally a distance forming an air gap (103; 115) away from each other.
