Why add a release valve
Unregulated airline vs. a pressure release valve
Left unchecked, back-pressure in an aeration airline works your compressor harder and can invite freeze-up in winter. Adding a release valve keeps the line running at its best.
Common approach
Airline with no pressure relief
- Back-pressure climbs as conditions turn cold
- The compressor carries a heavier load
- Winter freeze-up in the airline becomes more likely
