More ventilation in next to no time

If you need to increase the ventilation capacity or you have rooms completely lacking in ventilation, there’s a very simple solution.

We know that a good indoor climate with, among other things, a low CO2 level contributes to our general well-being and helps prevent us from coming home from work or school with a headache caused by poor air quality. With the knowledge that we now have about ventilation and the spread of infection, it is clear that good, effective ventilation has never been more important. REHVA (the Federation of European Heating, Ventilation and Air Conditioning Associations) has therefore, for the third time this year, updated its recommendations on ventilation.

In REHVA’s guidelines, they have thus made recommendations in relation to ventilation, which include having good ventilation for more hours than normal and no use of recirculation.


If you look at the latest recommendations regarding ventilation seen in the context of the use of Airmaster decentralised ventilation units, the following can be highlighted:


No use of recirculation

With an Airmaster decentralised ventilation system, each room has its own stand-alone ventilation unit, where fresh outdoor air enters the room directly, and used air is exhausted directly to the outside. The air is not recirculated.

Heat exchangers

Airmaster heat exchangers are countercurrent exchangers, where the incoming and outgoing air flows are always two completely separate air flows. The ventilation units also offer a high level of airtightness in relation to the internal leakage rate.

In the ventilation unit, polluted air from the room does not come into contact with the fresh air from outside.

Let the units ventilate for longer than normal:

Under normal circumstances, an Airmaster ventilation unit often runs according to a combination of demand management and time management. At a school, for example, units often run to a weekly schedule + demand management with CO2 sensors. Not only does this save energy, but it is also best for users of the room, as ventilation is provided as and when required.

Current recommendations are to let the ventilation run for longer than usual, and with a higher capacity. Both the time control and air flow settings are easy to adjust, and this can still be done on a room-by-room basis as needed.

We recommend that the ventilation units are allowed to run at full capacity for a few hours before and after using the room, and even at 30% outside operating hours, when they would otherwise normally be shut down.

Airmaster ventilation in brief:

  • Fresh air directly into each room
  • No use of recirculation
  • Easy to adjust the settings for air flow and time, etc.
  • Extremely quiet
  • Quick and easy to install
  • Can be connected and controlled online
  • Can be integrated with existing BMS

A decentralised Airmaster ventilation unit can, of course, ventilate a room by itself, or it can be used to supplement an existing ventilation unit that is unable to ventilate the premises sufficiently. Then you can just install an Airmaster in the room or rooms where ventilation poses the biggest problem.
