ABSTRACT:
A filter comprises an inner rigid metal tube connectable at its opposite ends to the fluid pipe line, and a spaced outer plastic housing enclosing the inner rigid tube. The latter is formed with two groups of holes through its wall, and with a deflector between the groups of holes for deflecting the fluid to flow through one group of holes, the space between the inner tube and the other housing, and the second group of holes. A filter body is disposed in the space between the outer plastic housing and the inner rigid tube.
Two embodiments of the invention are described, one being an in-line construction wherein the filter body is coaxial to the inner rigid tube, and the other being an off-line construction wherein the filter body is at right angles to the inner tube.
