2.6. Function of the unit
ComfortAir is a decentralized ventilation system with built-in heat recovery designed for
ventilation in educational facilities, office environments, and similar settings.
ComfortAir utilizes a counterflow heat exchanger (5.). The system efficiently utilizes the
already heated indoor air to warm up the fresh outdoor air by transferring the heat energy to
the supply air in the heat exchanger.
Airflow: The supply fan (6) draws fresh outdoor air through the intake duct (1) and supply
filter (10), and blows the air through the heat exchanger (5), from where the air is blown
through the supply grille (4) and evenly distributed into the room. The exhaust fan (7) draws
room air through the exhaust grille (3), through the exhaust filter (13) and the heat exchanger
(5), and exhausts the air through the exhaust duct (2).

When installing ComfortAir, it is possible to create openings either through the wall, through
the roof, or a combination of both.

3.3. Minimum distances
The minimum distance that the system should have from other walls, cabinets, or similar
objects is described in the table below. Please note that the distance is not the same for
both sides, as it is necessary to provide optimal space for the exhaust grille.
•N describes the minimum required distance to be able to remove the decorative
side panels of the unit.
•O Describes the minimum required distance from the ceiling to be able to open the
service doors of the unit.
•P Describes the minimum distance from the exhaust grille to the wall.
•Q Describes the width of the installation without the side panels against the wall.
The sum of N, P, and Q describes the minimum distance required between 2 walls or other
features, for the system to function optimally and be accessible.
