No air recirculation with an Airmaster ventilation unit

In Airmaster’s decentralised ventilation units, the air is not recirculated. Exhaust air from the room is transported directly outside – it is not moved from room to room. The exhaust air is sucked out through the ventilation unit, where it gives off heat (energy) in the heat exchanger, which is used to heat the fresh air that is introduced to the room.

Stand-alone ventilation unit with separate air flows

The supply air and the exhaust air are kept completely separate from one another in an Airmaster ventilation unit – fresh air enters without coming into contact with the exhaust air in the ventilation unit at any point.  

In the highly efficient countercurrent heat exchanger, the energy is transferred from the warm exhaust air to the colder, fresh supply air coming in. This transfer of heat/energy takes place via heating/dissipation of heat to/from aluminium plates without mixing fresh air and polluted air.

Airtightness class (air leakage)

Not only do Airmaster ventilation units have completely separate supply and exhaust airflows, but they also have a very high airtightness class and have been tested in accordance with both the EN 1886 and EN 13141-1 classifications.

What is air recirculation and why is it used?

Some manufacturers develop ventilation systems with air recirculation, as a certain airflow is needed to ensure proper air distribution. In these cases, they opt to recirculate some of the air to avoid having to heat or experiencing energy loss on the entire airflow.

Another reason for recirculating room air is the use of rotary heat exchangers. As these are not airtight, recirculation is an undesirable side effect of choosing this technology.

Why Airmaster does not recirculate air

The ventilation unit is located in the room where fresh air is required, usually close to an outer wall, which counteracts energy and heat loss during transportation of the air. There is no problem with changing the airflow when less is required. The combination of an airtight and energy-efficient heat exchanger and the absence of a duct system takes away any need to worry about air recirculation with Airmaster ventilation units.
