Centralised Mechanical Extract Ventilation (MEV)

A simple system that is liked by developers as it is simple to install during the build of the property. Ideal for new build appliacations. Centrally located, the system extracts stale and moist air from the wet rooms.

Centralised Mechanical Extract Ventilation (MEV) is a  whole dwelling ventilation system that supplies and extracts air continuously at a low rate. It is a low energy, continuous mechanical extract ventilation system designed with multiple extract points to simultaneously draw moisture laden air out of the wet rooms (bathrooms and kitchen) providing a quieter and more efficient system compared to separate fans.

Centralised Mechanical Extract Ventilation (MEV) is a system where a central unit is mounted in a loft or cupboard and ducted to extract polluted air from the wet rooms of the house. As there is no heat recovery, there is no requirement for any ducts to supply the replacement air. Instead, replacement air enters the home through window vents or airbricks. In many houses however, air naturally enters the building through gaps and cracks in the structure, providing adequate ventilation.

The removal of pollutants, such as moisture and build up of indoor air pollutants are all important factors in maintaining good indoor air quality, helping to create a better living environment.

Some MEV units will include a humidity sensor, designed to increase the fan speed in proportion to relative humidity levels, saving energy and reducing noise

With the growing concerns about over ventilating properties, the Multivent MVDC MS offers the option of ‘Close Control’ both in the residential and the commercial sectors. With a DC motor the Multispeed Multivent is one of the most efficient central extract units in the UK. The unit has 2 fully variable speeds for trickle and boost, with a switched live (LS) activation for the boost speed. An additional third speed (purge) is available using a second switched live connection.

The Multivent continuous mechanical extract ventilation range is designed for the simultaneous ventilation of separate areas in the home or as a multi-point extractor system for a wide range of commercial applications. In the home the system is usually located in the loft or airing cupboard with ducts taken to the bathroom, kitchen and utility room to remove water vapour at source and from WC's to remove odours. Designed to provide 0.7 of an air change based on the volume of the building, the Multivent system provides adequate ventilation, even in a 'tight' dwelling. Pollutant concentrations and humidity can be controlled. The Multivent H versions are now available with 2 control options. An integral humidity sensor that will detect any rise in humidity within the system and will boost between any 2 of the 3 speeds. A new Wire-less Controller is available for use with the Multivent H with 3 speed options offering total control of the systems. Multivent MV250 and MV350 are guaranteed for 2 years with an extended motor guarantee to 5 years offered on the MVDC LoWatt Energy Saving model.
