Why Choose the nVent HOFFMAN EDA40 Pressure Compensation Plug?
The nVent HOFFMAN EDA40 is a high-performance plastic pressure compensation plug designed to equalise pressure differences between the inside and outside of electrical enclosures while helping reduce the risk of dust and moisture ingress. As part of the HOFFMAN climate control accessory range, it provides a reliable solution for maintaining enclosure protection in environments with changing temperatures.
Temperature variations inside sealed enclosures can create pressure differences that may draw in moisture or contaminants. The EDA40 uses an integrated waterproof membrane that allows air and humidity to escape while only permitting dry air to enter, helping protect sensitive electrical components and improve enclosure reliability.
Featuring an IP66 / IPX9K protection rating, M40 x 1.5 mounting thread and a compact design with approximately 37 mm height and 60 mm depth, the nVent HOFFMAN EDA40 provides effective pressure management for industrial electrical cabinets and automation enclosures.

Reliable Pressure Management for Industrial Enclosures
The nVent HOFFMAN EDA40 pressure compensation plug helps maintain enclosure integrity by controlling pressure fluctuations caused by rapid temperature changes. This reduces the likelihood of moisture accumulation and supports improved protection of electrical and automation components.
Designed for professional enclosure installations, the EDA40 can be fitted to suitable cabinets to improve climate management without compromising the enclosure protection level. For optimal pressure compensation, nVent HOFFMAN recommends installing two plugs on opposite sides near the top of the enclosure.
Typical Applications
- Industrial electrical enclosures.
- Automation and control cabinets.
- Outdoor electrical cabinets.
- Machine building enclosures.
- Switchgear and distribution systems.
- Industrial equipment requiring pressure equalisation.
