How does a MEV system work?
A continuous Mechanical Extract Ventilation (MEV) unit sits centrally, usually in a loft or cupboard, and quietly extracts stale, humid air from wet rooms (kitchen, bathrooms, WCs) through ducts, expelling it outside. Running continuously, it controls moisture and pollutants across the whole home.
What is the CMEV.4E for?
It's one of Greenwood's most popular central extract solutions, a low-energy, continuously running unit for whole-house ventilation, centrally mounted in a cupboard or loft and ducted to the wet rooms.
Can it replace an older Greenwood unit?
Yes, it's a modern update of the Greenwood Centair/CML and is designed as a drop-in replacement, with improved energy efficiency, performance and noise specifications.
How many rooms can it serve?
It houses five staggered round extraction spigots, typically taken from the kitchen, bathrooms and WCs, with the stale air expelled through a single exhaust duct to outside.
Does it have humidity control?
No, this is the standard model. For humidity and timer control, choose the CMEV.4eHT.
What ducting is recommended?
125 mm (5") solid ducting is recommended to minimise air resistance. It uses a low-energy DC motor and carries a 2-year warranty; install by a competent person.
