Nvent AVDR4SS4 Enclosure Vent Drain Nema 4 4X

Product Description

The NVENT AVDR4SS4 is a gravity-fed vent drain designed to remove collected liquids from sealed electrical enclosures without allowing contaminants to enter. Constructed with a corrosion resistant polyester body and a 304 stainless steel sleeve, this drain measures 1.38 inches in diameter by 2.64 inches in length. It features a one-way mechanical shut-off that closes when internal pressure equalizes, keeping water and debris out while liquid drains freely under gravity. Licensed electricians and panel builders install this component in NEMA 4 and NEMA 4X rated enclosures to protect internal electrical and electronic components from moisture-induced corrosion.

This drain is suited for use in industrial and commercial NEMA 4 and NEMA 4X enclosures, including control panels, junction boxes, and equipment housings exposed to washdown, weather, or condensation. It is a passive device requiring no wiring or external power, making it appropriate for retrofit or new installation in environments where liquid ingress and corrosion are ongoing maintenance concerns. Typical applications include manufacturing facilities, outdoor utility panels, and process control enclosures.

Key Features

• Gravity-operated drain removes collected liquids without mechanical intervention
• One-way mechanical shut-off prevents water and contaminants from entering when pressure is equalized
• Corrosion resistant polyester body with 304 stainless steel sleeve for long-term durability in wet environments
• Rated for NEMA 4 and NEMA 4X enclosures with IP66 protection level
• UL 508A, CUL, and CSA C22.2 listed; RoHS compliant
• Compact footprint at 1.38 inches diameter by 2.64 inches length for easy panel integration

Compatibility

Designed for use with NEMA 4 and NEMA 4X rated electrical enclosures. Suitable for panel assemblies built to UL 508A standards.

Installation Notes

Installation is typically performed by a licensed electrician or qualified panel builder. De-energize and lock out the enclosure before drilling or modifying the panel wall for drain installation, in accordance with NFPA 70E lockout/tagout procedures. Mount the drain at the lowest point of the enclosure to allow full gravity drainage. Verify the installed drain position does not compromise the NEMA 4 or 4X integrity of the enclosure after fitting.
