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.

Controllability

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.
