ABSTRACT:
The present invention is a two piece frame embodiment in which a novel diaphragm inflation assembly and method are provided. Primary pieces include a two piece frame, two diaphragm pieces and two filter cloths integral with rubber gasketing. The two piece frame defines substantial voids to reduce weight, the two pieces comprising mirror image pieces. The intent of this embodiment is to reduce the weight, and therefore material and handling effort, of the prior art filter plates.
