AM 150

AM 150 is the smallest Airmaster decentralised ventilation unit, with heat recovery. AM 150 is designed especially for small rooms such as offices seating one or two people, as well as small meeting rooms and group rooms.

With AM 150, you get a unit that is particularly suitable for 1–2-people offices and small group rooms in offices, at schools or at institutions. In short: small rooms where a comfortable indoor climate is required, contributing to comfort and well-being.

AM 150 is a horizontal wall/ceiling-mounted unit, with the supply and exhaust at the rear. The ventilation unit is produced to the same high quality as Airmaster’s other products, using quality components, EC energy-saving motors, a countercurrent heat exchanger, etc.

With options such as motion sensors and CO2 sensors, it is possible to demand-control the ventilation unit according to how many people are in the room at a given time. The fully automatic control can also be combined with Airmaster Airlinq® Online.

Offering the option of installing the AM 150 on the wall or on a ceiling frame, it is also an obvious choice for modular buildings. It can be fully visible, or you can choose to partially integrate it into the ceiling so that only the lower section is visible. It is possible to pipe the exhaust, making it possible to install the ventilation unit above a diffuse ceiling, or connect the exhaust from an adjoining room.

Examples of applications

  • 1–2-person offices
  • Small meeting rooms and the like
  • Modular buildings
  • Hotel rooms

Throw lenth

The ventilation unit diffuses the supply air to varying degrees depending on the slat settings. This is shown in the illustrations, which indicate the diffusion pattern and throw at the different slat settings.
The airflow also influences the throw.
