Pressure Vacuum Vents

749 Pressure Vacuum Vents

Pressure vacuum vents are installed on the top of underground and low volume aboveground storage tank vent pipes. Vent allows tank to "breathe" during filling and discharging operations. Pressure and vacuum poppets seal vapors in tank when pressure is equalized. Settings are approximate.

The 749T provides the same functions as the 749 and is designed for use on underground and low volume aboveground tanks storing Diesel Exhaust Fluid (DEF) and other products requiring Teflon and Stailess construction.

  • Screen protects the tank from debris and insects
  • Integrated internal drain port channels water away from the tank
  • Vent vapors up and outward per NFPA 30
  • Conserves fuel
  • Certified CFH ratings
