In the event of primary system check valve leakage, the Schultz Air Guard check valve will prevent air from entering the filter vessel via the air eliminator.


Introducing air into the filter separator increases risk of internal fire as well as contributing to microbiological growth. This check valve is easily installed above the air eliminator.


Check valve body, poppet and spring are constructed of stainless steel. O-Rings are Viton.
