Continuous extract fans (dMEV) in Fife
Quiet low-energy fans that run all the time and boost automatically when humidity rises, across Fife.
- From £330 inc VAT per fan
- Free survey
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.
Fife has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.
