ABSTRACT:
An in-line point of use filter includes a restrictor flow valve and pressure gauge port integral therewith. The filter includes an internal threaded spindle which rigidly retains a coalescing filter in place. As a result of the compact spindle and filter arrangement, the entire filter assembly fits under a suction feed paint sprayer and allows the combined sprayer and filter unit to stand without toppling. The threaded spindle threads coaxially with a valve body and conducts compressed air therethrough. The compressed air passes from the threaded spindle directly into the filter media and transversely therethrough, and then from the filter media on to the external filter housing and longitudinally therewith into a small chamber carrying the pressure gauge port, the small chamber which is coupled directly into the sprayer body air inlet.
