ABSTRACT:
Disclosed is an air filter apparatus having a separator chamber formed by a housing in which a barrier type filter element is mounted to an annular backflushing air reservoir or manifold having a bore therethrough on a unitary support member which may be removed from the housing through the manifold bore. Reverse flow filter element flushing air discharge heads are mounted to the manifold and disposed over the filter element clean air discharge chambers and are movable away from the manifold bore so that the filter element may be inserted into and removed from the separator chamber. The filter element support member is secured to the manifold by pins which support a flange for movement relative to the housing to relieve pressure differentials across the filter element to prevent rupture of the element or minimize the hazard of failures elsewhere in the filter system.
