Façade ventilation grill

Airmaster Boomerain® façade ventilation grills

With its special geometry and aerodynamic design, Boomerain® - Airmaster’s own range of façade ventilation grills – has some truly unique properties. Boomerain is therefore “patent pending”.

The shape of the slats has been designed in such a way that only very limited turbulence occurs on the reverse of the façade ventilation grill. Pressure loss is thus reduced, and energy consumption is reduced considerably. The unique geometry is furthermore designed to capture water droplets and channel them away, preventing penetration into the duct.

Boomerain’s aerodynamic design means that it is now possible to reduce the diameter of the duct connection on several Airmaster ventilation units, and thus the diameter of the hole in the façade, without additional pressure loss and entrainment of rainwater.

Boomerain dimensions:

Ø160 – fits Airmaster AM 300
Ø250 – fits Airmaster AM 500
Ø315 – fits Airmaster AM 800, AM 900, AM 1000, AM 1200 and DV 1000

We install Airmaster ventilation units in vastly different geographical conditions in Europe – from a mild inland climate to the harsh west coast climate in Norway, for example.
Different weather conditions pose different challenges for a façade ventilation grill. We’ve addressed this by producing three different versions.

What you get with the Boomerain façade grill:
The diameter of the hole in the façade can be reduced without additional pressure loss. Several sizes of Boomerain for a uniform appearance on the façade. The entrainment of water is prevented, even at high air velocities. Energy consumption is reduced and makes unit quieter.

Airmaster Boomerain Data Sheet

Airmaster Boomerain® -1

Airmaster Boomerain® -1 is a façade ventilation grill with a single layer of slats, which is ideal for an ordinary inland climate under protective conditions in a relatively passive environment.

Airmaster Boomerain® -2

Airmaster Boomerain® -2 is a façade ventilation grill with a double layer of slats, providing greater protection from rainwater. We recommend it in more exposed places, which are occasionally lashed by westerly winds, for example.

Airmaster Boomerain® -3

Airmaster Boomerain® -3 is a façade ventilation grill with three layers of slats, which are extra effective at keeping the rain out. It is designed for harsh weather conditions, such as in coastal areas where extra protection may be needed.

Façade grille

Façade grille supplied with built-in bird net, and protects against driving rain.

Wall cover

Wall cover for the AM 900 - used when supply and exhaust have to be close together and prevents external short circuit.

Storm cap

Storm cap can be used when the supply and exhaust are particularly exposed to wind.

Bird nets for Boomerain® facade grilles

We supply bird nets for all 3 sizes and all variants (-1, -2 and -3) of Boomerain® facade grilles.

The bird net can be retrofitted to already installed Boomerain® facade grilles. Mounting is done by clamping the bird net to the ventilation duct behind the Boomerain® grille, and therefore does not require any tools for mounting.
