Nuaire's range of Mechanical Extract Ventilation systems - also known as Multipoint and Central Extract - are low profile and low-energy, offering simple and cost-effective installation and low life cycle costs for occupants. MEV is an ideal ventilation solution for apartments where there is possibly only one external wall, or in homes with one or more wet rooms.

Essentially the concept is to provide simultaneous, low level extraction from kitchens, bathrooms, shower rooms, utility rooms and toilets to a central extract fan via a system of ductwork and grilles. The extracted air is then normally discharged to outside via a single duct and grille/cowl. Current Building regulation requires such systems be designed to provide background extraction at a rate equating to approximately 0.5 air changes per hour based on the whole dwelling volume with the ability to boost by 25-50% for times when increased ventilation is required e.g. during cooking.

Replacement air is normally able to be provided via structural air leakage with background ventilation openings like trickle vents not normally needed unless the home is built to extraordinarily airtight standards. This can be best demonstrated by referring to the table below which shows the very small building fabric air resistance an MEV system on boosted extraction would have to overcome in apartments of different levels of airtightness. As this type of system has to work 24 hours a day, 7 days a week, 365 days a year, low noise levels and reliability are critical.

Our MEV systems are cost-effective and offer many benefits to home-owners:

  • Elimination of condensation dampness
  • Healthier living environment
  • Removal of musty odours
  • Low running costs and low-energy operation
  • Easy installation and low maintenance

Suitable Applications:

  • Ideal apartment ventilation solution where there is possibly only one external wall.
  • Homes with more than one wet room.
