Continuous extract fans (dMEV) in Lanarkshire

A dMEV (decentralised mechanical extract ventilation) fan is a low-energy extract fan that runs continuously at a quiet trickle speed and boosts automatically when it senses humidity or a light switch. Because it never fully switches off, moisture is removed steadily instead of building up between showers.

Our team is based in Great Barr, Birmingham, and we work throughout Lanarkshire, from Coatbridge, Airdrie, Motherwell, Rutherglen and East Kilbride. Surveys for new installations are free on the UK mainland, with a written quote afterwards.
