ABSTRACT:
Method and apparatus for filtering air are disclosed. A preferred cabinet collector (10) according to the invention includes a housing defining an upper chamber (b 20a) and a lower chamber (20b). Separating the chambers (20a, 20b) are a pair of wedge-shaped filter assemblies (38, 38'). First ends (42, 42') of the filter assemblies (38, 38') are attached the housing wherein second ends (44, 44') are free. Provision is made to automatically periodically move the second ends (44, 44') to clean the filter media, filter displacement apparatus "snapping" the filter assemblies (38, 38') and another displacement apparatus "vibrating" the filter assemblies (38, 38') to achieve the desired media cleaning.
