ABSTRACT:
A multiple-disc filter includes a pressure member located within the filter housing upstream of the discs forming the stack to press the discs tighter together when the fluid flows from the housing inlet to the housing outlet, and to permit the discs to move apart for cleaning the filter when the fluid flows in the reverse direction. Each filter disc is formed with alternating groups of radially-extending slots to define circumferential filtering passageways between the ends of the slots.
