Corrosion in fire sprinkler systems can compromise life safety by blocking water flow or causing pipes to leak. PURGEnVENT Model 7930ECA includes all of the benefits of our Model 7900 automatic air vent with the addition of an end cap for easy installation.
The unit comes pre-assembled. It features an automatic air vent in our patented conical design. This continuously vents air from the system with no leaks to prevent corrosion. Model 7930ECA can be installed on a new system or easily coupled onto an existing branch line.
