Also referred to as System 3 in Approved Document F of the Building Regulations, an MEV system consists of a centralised ventilation unit that continuously extracts waste, polluted and moist air from wet rooms and can be discreetly positioned in either a cupboard, utility room, ceiling or loft space. An MEV system can be ducted throughout the dwelling and operated by the homeowner through a range of control options.
Typically dual speed, MEV systems provide both low speed continuous trickle ventilation and high-speed boost flow when required. Replacement fresh air is drawn into the dwelling through background ventilators i.e. air inlets, located in the living areas.
The potentiometer-controlled speed selector allows accurate setting of 3 airflow speeds
The unit has 3 fully variable speeds for trickle and boost,
A switched live (LS) can also be used to select boost speed
An additional third speed (purge) is available using a second switched live connection.
PVC outer casing with an acoustic lining is included as standard, ensuring minimum noise levels.

All three speeds are manually adjustable at the wiring centre to facilitate Building Regulation commissioning speeds.
