H2Omit Series Vent Drains, Smooth Matte Finish, 2 In Length
Hoffman vent drains are used for draining out accumulated water from the bottom of the enclosures. These NEMA-rated units are made of corrosion-resistant polyester that protects the internal electrical and electronic components from fretting and functions on gravity to remove the collected liquids. They feature a one-way mechanical shut-off that helps to reduce the harmful effects of temperature-induced vacuum that could further force water and contaminants from entering into the enclosure. These UL-listed vent drains are ideal for installation on a 7/8 inch hole in the bottom of the enclosures (mild steel, aluminium, stainless steel or non-metallic) with the help of a nut or 1/2 inch threaded conduit hub.
