MEV (Mechanical Extract Ventilation)

An MEV or CME (Continuous Mechanical Ventilation) system uses background ventilators, usually trickle ventilators fitted in windows and a centrally located continuously running mechanical extract fan with ducts running from the moisture producing areas or "wet rooms" such as kitchens and bathrooms. The background ventilators provide the whole building ventilation and the central mechanical extract fan runs continuously to remove odours and excessive humidity.

A boost facility provides rapid extraction when necessary to remove higher levels of pollutants.

As an alternative, continuously running localised fans, also known as dMEV (decentralised Mechanical Extract Ventilation), ducted to extract areasmay be used in place of MEV.
