391 Breather Valve

391 Breather Valve

Despite its small 2-inch size, the 391 breather valve provides a strong flow profile of 20 cfm at 0.4 psi. Included is a manual relief feature to equalize internal pressure to make opening the container easier. One application that utilizes the 391 is a medium-sized, fiberglass shipping container for transporting propellers.
