ABSTRACT:
A dirty gas inlet arrangement for a filter housing including an inlet housing connecting an elongated outlet in a dirty gas supply manifold to the dirty gas chamber of the filter housing. The inlet housing is provided with a downwardly sloping bottom wall causing particulate materials separating from the dirty gases to flow into the dirty gas chamber, and a damper assembly for selectively closing off the elongated outlet in the manifold to prevent dirty gases from flowing into the dirty gas chamber. The damper assembly includes a shaft rotatably supported within the inlet housing, a lever arm cantilevered from the shaft, an elongated damper blade sized to underlie the marginal edge of the outlet pivotally secured to the free end of the lever arm, and an actuating assembly for selectively rotating the shaft to lift the blade into sealing engagement with the marginal edge of the outlet and to lower the blade into an inobtrusive position adjacent to the bottom wall.
