Kair Heat Recovery Unit
Kair Heat Recovery Room Ventilators provide a continuous air change all year round, replacing stale and moisture-laden air with filtered, fresh and warmed air from outside.
These units provide an effective solution to condensation and mould growth problems in any room in which they are fitted. They are ideal for tackling condensation in kitchens, bathrooms, utility rooms, living rooms, lavatories, washrooms, conservatories, offices and bedrooms. They dramatically improve the quality of the indoor air supply, benefitting the health of inhabitants.
How Heat Recovery Units Work
As the stale air is drawn out, it passes over a heat exchanger, which traps (recovers) the heat from the outgoing air in order to warm the incoming fresh air.
When humidity levels increase, the unit automatically switches to a boost mode. You have the ability to set the humidity level isolating transformer at which boost mode is activated to ensure that condensation does not occur. When humidity levels have returned to an acceptable level the heat recovery unit returns to its standard trickle mode. The continuous controlling of Relative Humidity levels ensures that condensation and mould growth does not occur.
Benefits of Kair Heat Recovery Units:
Unlike conventional extractor fans which suck out and waste expensively produced heat, Kair Single Room Heat Recovery Ventilators recover up to 86% of exhaust heat, even when operating on boost mode. By replacing conventional extractor fans with heat recovery systems you could save at dramatically reduce energy loss. The Kair unit is also low energy with minimal running costs.
Kair units reduce humidity to optimum levels, which eradicates condensation and prevents mould growth. They also rapidly remove pollutants such as volatile organic compounds (VOCs), allergens such as dust, oxides of nitrogen, carbon monoxide, carbon dioxide, tobacco smoke and unpleasant odours. Ventilation is necessary to maintain a healthy and comfortable internal environment for you and your family.
The Kair™ ‘through-the-wall’ units are easy to install using a 152mm core drilled hole.

Very poor!Been an electrician for 27 years. This was one of the worst products I've had to fit. Spoke to the company and was mocked by someone for following the instructions and using adhesive to put the unit together AS PER INSTRUCTIONS. Apparently the instructions are wrong on more than one account. Finally managed to get the unit together with a bit of luck! Yet to see if it actually is any use up and running.

At lastHaving tried so many times to solve a damp problem in a let property I was about to give up when I found this product. I was wary when Permagard assured me that it would prevent the return of the dreaded mould, but it's been running for eight months now and the décor is unmarked. I wish that I had found this years ago.
