Abstract:
A bag-type filter having a removable filter element, said element being mounted in a cassette frame which may be inserted and removed from the filter housing. The filter element has a plurality of tubular sleeves which are open at the top and closed at the bottom to provide elongated gas passageways surrounded by filter material. The cassette frame includes stiffening members positioned within said sleeves and a rectangular frame surrounding the top of the filter element. The filter element is suspended from said rectangular frame and is releasably clamped to the frame. The cassette frame has a lower structure which may support the cassette outside the housing and provide reinforcement for the cassette. The stiffening members include elements engaged in the sleeves to hold them open, the elements comprising a wire lattice having offset guide portions adapted to engage in the closed bottoms of the sleeves. The lower structure of the cassette frame includes end walls which engage the sleeves and cooperate with the stiffening members in maintaining the passageways open.
