Overview

Protect your UL/cUL Type 4, 4X enclosures with the nVent H2OMIT Vent Drain, Type 4 Stainless Steel (SKU: AVDR4SS4). This robust device, engineered by nVent, ensures the integrity of your enclosures by facilitating the egress of accumulated water and equalizing air pressure. The H2OMIT Vent Drain uses gravity to efficiently remove liquids, preventing water damage, corrosion, and short circuits. Crucially, it functions as an air pressure equalizer, mitigating the harmful effects of temperature-induced vacuums that can draw ambient moisture and contaminants into the enclosure. A one-way mechanical shut-off activates upon pressure equalization, effectively blocking ingress. Constructed with a corrosion-resistant polyester material and a durable Type 304 stainless steel sleeve, this vent drain is built for demanding industrial environments. It maintains the enclosure's UL Type 4X rating when properly installed. Installation is versatile, fitting into a 7/8-in. hole with the provided nut or a 1/2-in. NPT/NPS threaded conduit hub. Compatible with mild steel, aluminum, stainless steel, and non-metallic enclosures. Specifications include a 2.00-in. length and 1.38-in. outside diameter. It meets IEC 60529 IP66 and NEMA/EEMAC Type 4, 4X standards, and is UL 508A Listed (File No. E61997) and cUL Listed per CSA C22.2 No 94 (File No. E61997).
