ABSTRACT:
A latch assembly for removably clamping a unit filter cell in position against a flow-through frame structure includes a shaft spaced from the flow-through frame structure and mounted for rotational movement about its longitudinal axis and for movement transverse to its longitudinal axis toward and away from the flow-through filter frame. The shaft also includes filter cell contacting elements. The shaft is also biased toward the flow-through frame structure. A unit filter cell is disposed between the shaft and flow-through frame structure and is held in place against the frame structure upon rotation of the biased shaft which brings the filter cell contacting elements into contact with the unit filter cell.
