Façade ventilation grills in new aerodynamic design

Airmaster Boomerain® Ø315

Airmaster introduces a new façade ventilation grill that with its special geometry and aerodynamic design makes it possible to reduce the diameter of the hole in the façade for an AM 1000 ventilation unit. Where a Ø400 mm bushing was previously used, a Ø315 mm bushing now suffices – without extra pressure loss and/or entrainment of rainwater.

Aerodynamic Design

Being able to reduce the diameter from Ø400 mm to Ø315 mm was a project that was achieved by drawing on Airmaster’s expertise in the field of aerodynamics. 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.

Façade ventilation grills for all weathers

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. from the outside, they are identical, making it possible to mount different façade ventilation grills on the same building if required.

Benefits

• The diameter of the hole in the façade can be reduced from Ø400 mm to Ø315 mm
• The entrainment of water is prevented, even at high air velocities
• Energy consumption is reduced
• Quieter
