Breather Vents
How It Works
|
1. As internal pressure nears the pre-set cracking level, it presses the plunger upward until the resilient seal clears the port, allowing the outflow of air. 2. Since this vent permits two-way air flow, it can also relieve a vacuum which can cause cavitation. The vacuum is cracked when the plunger is pulled down from the seal, allowing an inrush of air. Filtered
Pressure/Vacuum Relief Vents These multi-purpose breather vents safeguard against extreme pressure or vacuum build-up while filtering out dust and other contaminates which can impair the functioning of expensive equipment. |
