The AVDR4NM is a non-metallic vent drain accessory manufactured by Hoffman Enclosures, Inc. Constructed from corrosion-resistant polyester, this component measures 2 inches in height and 1.25 inches in width. It is designed for use with NEMA Type 4 and 4X enclosures, providing an IP66 protection rating. The unit functions as both a water drainage outlet and an air pressure equalizer, ensuring internal environmental stability while preventing moisture accumulation within the enclosure structure.

Feature Summary

• Functions as an integrated water drainage and air pressure equalization system
• Constructed from corrosion-resistant polyester material for durability
• Designed specifically for NEMA Type 4 and 4X enclosure applications

Applications

• Drainage of accumulated water from the bottom of industrial enclosures
• Air pressure equalization within sealed electrical housings
• Installation in NEMA Type 4 and 4X compliant enclosure systems

Procurement Notes

Verify that the specified part number matches the required NEMA Type 4 and 4X compliance standards. Confirm that the corrosion-resistant polyester material meets the environmental conditions of the installation site. Ensure the physical dimensions align with the existing enclosure mounting requirements to guarantee proper fit and function.

Selection Notes

Select this component when a non-metallic solution is required for moisture management in harsh environments. The corrosion-resistant polyester construction makes it suitable for applications where metal components might degrade. Ensure the application requires both drainage capability and pressure equalization within a NEMA Type 4 or 4X rated housing.
