Design

The outer casing is made of high quality and durable plastic. The internal perforation of the casing allows sound waves to pass through, directing them at a certain angle onto a layer of sound-insulating material.

Heat- and sound-insulation of the casing are made of a 50 mm layer of non-flammable mineral wool.

The special perforation of the casing and the sound-absorbing material ensure that sound is attenuated over a wide frequency range.

Due to the conic impeller and special blade profiling the circumferential air speed increases thus providing higher air pressure and capacity as compared to standard axial fans.

The diffuser, the specially profiled impeller and the directing vanes at the outlet of the fan casing distribute air flow in such a way as to attain the best combination of high performance and high pressure at low noise level.

The fan casing is equipped with an outer airtight terminal box for connection to power mains.
