Vent Drain Accessory

The Hoffman AVDR4NM is a polyester vent drain designed for electrical enclosures. It allows accumulated water to exit from the bottom of the box. This component suits installers protecting electrical equipment in outdoor or humid environments.

Polyester Material Limits

The polyester construction resists corrosion and offers a matte finish. It functions as a passive drainage point without active sealing against pressurised ingress. Installers must verify the enclosure cut-out matches the accessory dimensions for a proper fit.

Enclosure Mounting Implications

The drain mounts at the enclosure base to let gravity remove condensation. Its polyester body withstands typical industrial atmospheres without rust. The accessory adds a single penetration point that requires correct sealing during installation to maintain the enclosure rating.
