ProAir PA750LI  – Enhanced Indoor Air Quality and Energy Efficiency

The PA 750LI was designed for larger homes up to 300m² in size.  The unit includes an updated Visual Control with sensors to monitor Temperature, Humidity and Total Volatile Organic Compounds (TVOC) for enhanced Indoor Air Quality (IAQ). The unit also includes a Summer Bypass as standard and has a Specific Energy Consumption (SEC) rating of A+. The system uses the Humidity & Temperature sensors to automatically control both the Summer Bypass and Boost function.  The PA750LI operates continuously at low speeds to minimise the electrical consumption (~50% running cost of conventional MVHR units) while ensuring system compliance with Part F 2019 Building regulations

Clean Fresh Air Continuously

Filtered fresh air is circulated throughout your home day and night. On average most people spend over 80% of their time indoors. 50% of all illnesses are either caused by, or aggravated by poor indoor air quality. The ProAir HRV System will continuously remove stale moist air from your home creating a more suitable and healthy place to live.

Energy Efficient Ventilation

A Heat Recovery Ventilation system will save you money and reduce your energy requirements for heating by re-using the heat that is normally lost through poor construction. A Heat Recovery Ventilation system is also designed to operate continuously at a low rate to minimise the electrical energy consumption.

Condensation Elimination

All water vapour will be removed as it is produced. As a result there is no moisture condensation which causes rot, damp, condensation or mould growth.


Comfort levels are superior in a house fitted with a Heat Recovery Ventilation system/unit. Irrespective of weather conditions, draught free balanced ventilation is provided all the time.

  • 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”

  • “Installed a full MHRV system in our house we were renovating. Found them very competitively priced and very easy to deal with on technical issues. Highly recommend”

    M. McDonagh
  • “ProAir installed a system in our house in 2008 and never had a day’s problem with it! The air is always fresh and the knock-on effect is, a healthier environment to live in”

    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"
