ABSTRACT:
A filter assembly having an extruded filter head. The extruded filter head is composed of a generally flat base and a domed upper section which is connected to the side edge of the base. A central wall extends between the base and the upper section and defines longitudinally extending inlet and outlet chambers, each of which has a uniform cross section throughout its length. Fluid to be filtered is introduced into the inlet chamber and is withdrawn from the outlet chamber. One or more filters are mounted on the underside of the base. Each filter is provided with an inlet opening which is connected through a port in the base to the inlet chamber and is also provided with an outlet opening which is connected through a second port in the base to the outlet chamber. The extruded construction provides improved mechanical strength for the head, and substantially reduced porosity as compared to a cast head.
