Mechanical Extract Ventilation
Mechanical Extract Ventilation (MEV) is a whole-house ventilation system that extracts air continuously at a low rate from wet rooms. Because the system operates continuously, it creates negative pressure in the building. Replacement air is introduced to the building through either window or wall vents (or a combination of both). This system provides much better protection against condensation and mould than the traditional intermittent extractor fans.
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.
Continuous mechanical extract ventilation is designed to work at a low background level of extraction with an occasional boost when required.
Benefits of MEV Systems
Improved Indoor Air Quality
Maintain a healthy & comfortable indoor environment inside your house free from stale air and pollutants. Helps control humidity, VOC’s and odours within your home.
Cost Effective
Using a single, central extractor fan unit is more cost-effective in houses than having individual extractor fans (with their individual wiring, switches, holes through walls, grills, etc) in each area requiring ventilation.
Continuous Operation
The central mechanical extract fan runs silently and continuously at predetermined rates to remove pollutants and excessive humidity without switching the extraction fan on or off.
Easy Installation & Low Maintenance
Unlike MVHR, MEV Systems are fairly easy to install and require little to no maintenance.

How do MEV Systems Work?
Continuous mechanical extract ventilation (MEV) systems constantly remove moisture-laden air from the kitchen and wet rooms by connecting a remote central fan to multiple extract valves via ductwork.
The central extract fan is typically located in a loft space or hallway cupboard with a system of ductwork and grilles extending to each room requiring extract ventilation.
The extracted air is then normally discharged to the outside via a single duct and grille/cowl.
To save time and effort, continuous MEV systems can be linked to various switches or sensors that instruct the system to boost when necessary.
