FRPRO – Mechanical Extract Ventilation Unit (MEV)

A Mechanical Extract Ventilation (MEV) system provides continuous extract ventilation of stale and moisture laden air from wet rooms: kitchens, bathrooms, shower rooms, utility rooms, and toilets, to a central extract fan via a system of ductwork. The extracted air is then normally discharged outside via a single vent. Replacement air is provided via ventilation openings in the living/bedroom walls. MEV systems help provide good indoor air quality, protecting your home from condensation, damp, and mould.

MEV is a quieter and more efficient system compared to separate fans. The unit is mounted in the attic/ loft or in a cupboard and ducted to extract polluted air from the wet rooms of the house.

MEV is the basic requirement to achieve compliance under current building regulations (Ventilation-Part F) and is a cost-effective method of ventilating your home.

ProAir design, supply & install throughout Ireland, an end-to-end service to ensure your home will be healthy and comfortable. Our experienced design team provides bespoke solutions for each and every customer. In addition, our installation team work efficiently around other trades to ensure a smooth and timely installation. We can install an MEV system into new build properties or retrofit into most existing homes. ProAir works with many of the SEAI registered One Stop Shops who support people through the process of upgrading their home.

The difference between MEV and MVHR?

Whereas installing an MEV system provides only the extraction of stale air, installing an MVHR system provides you with a fully balanced ventilation system throughout your home, as it combines the extraction of stale, moisture laden air and the supply of fresh, filtered and passively heated air to all rooms. This results in a far more energy efficient system than MEV and a higher level of air quality in your home.

MVHR systems are of additional benefit for areas with high air pollution because of the filter element, and for those who suffer from allergies or asthma. They are also ideal for areas with noise pollution as there is no necessity to open windows or doors to assist ventilation.

Based on the outlined additional benefits, ProAir would recommend the installation of an MVHR system wherever possible. If you are unsure which is the right system for you, please contact us, our sales team would be happy to discuss your options and recommend the correct solution for your home.

  • We have HRV in our block-built house. Installed by ProAir of Galway. Very professional and thorough job, highly recommended. Cost was c. 8k, but we have two units due to the size of the house. Been in constant operation since October, no issues so far. Complexity? Turn it on and leave it. When you have a shower/bath press boost. That’s it.

  • We also got ours from ProAir and are very happy with it. We were strapped for extra cash, but our geo-therm. guys recommended the MHRV as a way of making the whole system more efficient. No condensation is a great thing. Your house will be healthier overall.

  • Very happy with my ProAir Ventilation System. They system settings had to be changed to due the hot weather so they talked me through step by step on how to correct. They were extremely helpful. Superb customer service.

  • "We were fighting with a lot of dampness and mould using electric dehumidifiers with little success. The heat recovery ventilation system removed all of the problems. No more dampness, no more mould and our windows are dry in the morning. The installation was done quickly and professionally. Huge thanks to ProAir!"

  • “Very professional from start to finish, easy to work with and always available and willing to answer a technical question. The unit is very quiet, even on boost mode it’s hardly audible. From my research I found it to be the most efficient on the market also, and it’s manufactured here in Ireland. For the self-builder, I found ProAir very good to work with, they were flexible with the scope of works and the price reflected this. They furnished me with detailed drawings and all the ducting needed, they installed the unit and commissioned at the end, this suited my requirements perfectly”

    C. Cunningham.
  • “I contacted ProAir for advice and pricing for my self build. The customer service was brilliant and every staff member I encountered was very helpfully explaining the system and answering my queries. The staff who called to site were efficient and professional and called as per the agreed times. I have already recommended ProAir to a friend and would have no hesitation in recommending their services in the future”  

    S. Carr
  • “Extremely happy with our ProAir and their service in general, from my initial phone call to their site visit, installation process and after care service. I found them very easy and helpful to deal with, as well as good value. Constant fresh air and a handy display console to tell me if the system is working correctly or needs a filter change etc. Would highly recommend"
