nVent HOFFMAN AVDR4NM H2Omit Vent Drain, a non-metallic polyester enclosure accessory designed to remove accumulated water and provide pressure equalisation.
£108.00
The nVent HOFFMAN AVDR4NM H2Omit Vent Drain is a compact and reliable enclosure accessory designed to remove accumulated water from electrical enclosures while providing pressure equalisation to help protect sensitive electrical and electronic components. As part of the nVent HOFFMAN H2Omit Vent Drains series, it provides an effective solution for managing condensation in industrial enclosure applications.
This non-metallic vent drain uses gravity to allow collected liquids to escape from the bottom of an enclosure while a one-way mechanical shut-off helps prevent water and contaminants from entering when pressure is equalised. The corrosion-resistant polyester construction makes it suitable for installation in a wide range of enclosure materials.
With a compact design measuring 67 mm height and 32 mm diameter, the AVDR4NM is ideal for use in mild steel, aluminium, stainless steel and non-metallic enclosures where condensation management and environmental protection are required.
Condensation can create moisture-related risks inside electrical cabinets, potentially affecting sensitive components and reducing equipment reliability. The nVent HOFFMAN AVDR4NM H2Omit Vent Drain provides a practical method of removing collected liquids while helping balance internal and external enclosure pressure.
Designed for industrial enclosure applications, the H2Omit Vent Drain range supports reliable protection in automation, control and electrical installation environments where maintaining enclosure performance is essential.
