Product Details

AV4000 is a two vane louver air valve made from injection molded nylon. The large orifice design of the AV4000 provides a wide air flow pattern. The vane housing rotates 360 degrees for directional control of the air stream. The anti-rotation rib on the side of the housing prevents the air valve from rotating when adjusting the vanes.
