Continuous extract fans (dMEV) in County Tyrone
Quiet low-energy fans that run all the time and boost automatically when humidity rises, across County Tyrone.
- From £315 inc VAT per fan
- By arrangement
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.
Across County Tyrone the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Strabane, Dungannon, Cookstown and Omagh.

Usually yes. Most fit the existing hole or duct, which keeps the cost and mess down.

Visits here are by arrangement. Because of the ferry or long travel involved, we quote travel separately and in writing before you commit, and we can often combine visits to keep the cost down.
