Decentralised Mechanical Extract (dMEV) Fans:

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.

Motor

Single phase induction motor with pre-oiled bearings fitted for a long maintenance free life and protected by a thermal fuse.

Installation

Designed to be wall or ceiling mounted.

Wall kits comprise a wall sleeve (275mm long) and a fixed grille (white, terracotta, stone, grey or brown).

Installation through a wall requires a 107mm hole or if using a high-rise internal cowl 117mm.

Window kits comprise an external window grille and internal mounting plate.

Ceiling kits comprise 1.5m of 100mm dia flex PVC ducting and white external grille.

Performance

Extract rate of 98m³/hr, 27 litres per second on maximum speed.

SAP ratings of .73 w/l/s on slow speed and .52 w/l/s on medium speed.

Depending on which model is being used, upon installation, the fans need to be set for its environment. By setting the switch inside the unit to SLOW (bathroom), the fan will maintain the extract rate of 8l/s, or by setting the switch to MEDIUM (kitchen), 13l/s.

When the boost function is activated, the unit will extract at 27 l/sec.
