ABSTRACT:
A strainer is provided for removing particulate debris from a fluid passing therethrough. The strainer is primarily of the automatic type having a hollow body, a cover, a strainer element and a backwash arm assembly for cleaning the strainer element. The strainer element is a cylindrical, convoluted screen having encapsulating end caps positioned at either end. The end caps and thus the strainer element are retained so as to avoid rotation in seal rings, one of which is connected to the cover and the other of which is detachably connected to the terminus of the backwash arm. The strainer element is a structural member capable of withstanding the loads imposed on it by the fluid.
