ABSTRACT:
A moving manifold for back flushing open-mouthed filter bags so that the dust accumulated on the bags exterior is dislodged. The manifold distributes both continuously blower driven air and high pressure air from pulsed jets for back-flushing the bags. A back draft damper installed in the manifold is opened by the decreased pressure created when the high pressure air is activated in order to reduce structural stresses on the manifold and reduce the power required for the blower drive.
