Series 18540 Pipe-Away Conservation Pressure/Vacuum Breather Vent

Brand: Protectoseal Company
Request Information
The Protectoseal Series 18540, Pipe-Away Pressure / Vacuum Conservation Vent provides both pressure and vacuum relief to maintain tank's vapor space within safe operating parameters. 

Vent settings minimize loss of product. Under pressure venting conditions, tank vapors are piped away, rather than released into the atmosphere.
Features
  • Fast inspection, easy maintenance
  • Maintains accurate pressure settings
  • Air-cushioned seating
  • Automatic condensate drainage
  • Low-leakage
  • Sizes available
  • PRO-FLOW sizing and selection software
