How MEV Works

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.

Construction

PVC outer casing with an acoustic lining is included as standard, ensuring minimum noise levels.

Motor 

The appliance has a low energy, high efficiency EC backward curved centrifugal impeller fan/motor assembly with sealed for life bearings suitable for +50ºC to -25 ºC.

Installation

ceiling, wall or floor Installation is recommended
