How dMEV Works
Also known as System 3 in Approved Document F of the Building Regulations, decentralised Mechanical Extract Ventilation (dMEV) systems incorporate continuously running extract fans, designed to remove waste and moist air from a single wet room.
dMEV fans continuously extract the waste air at both low trickle or boost speeds, as determined by the homeowner through a range of control options. Replacement fresh air is then drawn into the dwelling via background ventilators located in the habitable rooms. As an added benefit incorporating a dMEV system will also help to lower a property’s Dwelling Emission Rate (DER) and therefore provide a higher SAP rating.
