CMEV.4 is a continuous running mechanical extract unit for whole house ventilation. It can be installed as a completely discreet system which is centrally mounted in a cupboard or loft space. its compact design makes it ideal for apartments and small properties. Stale air is extracted via remote grilles in each room. The system allows for five extraction ducts which are usually from the kitchen, bathrooms and toilets and are extracted via one exhaust duct to the outside. 125mm or 5" solid ducting is recommended to minimise air resistance.
The unit can be wired to run on low, medium and high speeds via a remote wired 3 position switch (GS1) or low and high only via a double pole switch (GS2). The motor speed is fully adjustable for low and high speeds (medium speed will be based on the mid point between the selected trickle and boost speed).
