A centralized system

AJ-Air wants to be responsible for the quality of your air.

We propose you to opt for a centralized system for all your new constructions.

A double flow ventilation to evacuate the condensation of wet premises (toilets, bathroom, kitchen) and reinject the energy into the living space (bedroom, living room).

A decentralized system

If you have an old home and you want to renovate in terms of ventilation, we are your solution.

It is not always possible to do the same thing with old builds. In this case, we recommend a decentralized system that allows you to process only one part. A simpler and cheaper solution.

Complete service for all your ventilation installations


Opt for controlled mechanical ventilation (CMV). Do not breathe polluted and stale air by the insulation and moisture of your home. CMV propagates fresh air without loss of heat. We install this system for you.


Whether for domestic or professional use, we are able to provide you with powerful ventilation devices. You benefit from a constant intake of fresh air or the ventilation of smoky or dusty rooms.


You work regularly on construction sites and you want a device allowing you to evacuate dust and rekindle fresh air in the rooms or tunnels that you invest? We can provide you with these mobile machines.

Service after sales

For a longer term solution, or repeating itself at certain times of the year, we recommend the purchase of heating systems! AJ-Air technicians, experts in heating solutions, will advise you according to your heating needs!
