Decentralised Mechanical Extract Ventilaton (dMEV)

Fresh Air, Room by Room

Modern homes are more airtight than ever which is great for energy efficiency, but not always for air quality. That’s where Xpelair’s dMEV solutions come in. Designed to continuously extract stale, humid air from individual rooms, dMEV systems are the smart, compliant way to ensure healthier indoor environments.

How does dMEV work?

A decentralised Mechanical Extract Ventilation (dMEV) system incorporates continuously running fans, designed to remove odours and humid air out of single wet rooms such as bathrooms and kitchens. dMEV fans operate continuously in each wet room of the property. They run at a low (trickle) speed unless boost speeds are activated by either an external switch or humidity. Because the fans are always in operation they provide a fantastic method of ensuring properties are always well-ventilated.

Why Choose Xpelair dMEV?
