Why Choose the nVent HOFFMAN EDAS40 Pressure Compensation Plug?
The nVent HOFFMAN EDAS40 is a high-performance stainless steel pressure compensation plug designed to equalise pressure differences inside electrical enclosures while maintaining a high level of protection against dust and moisture ingress. As part of the nVent HOFFMAN pressure compensation accessory range, it helps protect sensitive electrical and electronic components from condensation caused by temperature variations.
The EDAS40 uses a waterproof breathable membrane that allows trapped air and humidity to escape from the enclosure while only allowing dry air to enter. This prevents vacuum formation and reduces the risk of moisture accumulation inside sealed enclosures operating in environments with changing temperatures.
Manufactured from AISI 303 stainless steel with an NBR sealing gasket, the EDAS40 provides a robust solution for demanding industrial applications. With an IP66 / IP X9K protection rating, M40x1.5 mounting thread and compact installation requirements, it is suitable for use on electrical cabinets and industrial enclosure systems requiring reliable pressure equalisation.

Reliable Pressure Management for Electrical Enclosures
Sealed electrical enclosures can experience pressure fluctuations caused by heat generation from electrical equipment and changes in ambient temperature. These pressure differences can contribute to condensation, which may affect the reliability and lifespan of internal components. The nVent HOFFMAN EDAS40 helps manage these conditions by allowing controlled air exchange while maintaining enclosure protection.
The stainless steel construction and high IP protection make the EDAS40 suitable for industrial applications where reliable pressure equalisation is required. Installing pressure compensation devices correctly helps maintain enclosure performance and supports long-term protection of electrical equipment.
Typical Applications
- Industrial electrical enclosures and control cabinets.
- Automation and machine control panels.
- Switchgear and electrical distribution enclosures.
- Outdoor and harsh-environment enclosure installations.
- Industrial instrumentation cabinets.
- Electrical systems requiring condensation control.
