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.
We carry out continuous extract fans (dMEV) across Glasgow, including Glasgow. Prices use Scotland rates. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.
