Our Large profile series is the largest capacity filters/strainers available. They are used primarily in the same applications as the medium series, where increased flow rate and filtration area is required. Available in connection sizes from 1″ to 1-1/2″.

Our compact in-line vacuum filters offer the added protection of 10 micron filtration and a 150 PSI pressure rating for adverse conditions and environments. They are ideal for environments where glass materials can not be used and where there is a high level of moisture present.

Materials of Construction

Our filters are durable, constructed of rugged injection molded Nylon and Polypropylene plastic, and will not rust or corrode.

PFP offers a variety of different filter configurations with female connections standard ranging in size from 1” to 1-1/2”.
