Power Failure Risk

The air admittance valve reduces reverse flow during a sudden power failure.

Oil Backflow Prevention

The air valve allows controlled air entry to prevent oil backflow during an outage.

Pump Safety Function

It protects the rotor chamber by balancing pressure during a sudden power loss.

Reverse Flow Control

The valve quickly admits air to stop reverse oil movement in the pump system.

Operational Stability

The air admittance valve ensures stable operation during a sudden shutdown.
