Fan with diagonal impeller – ideally suited for cables with narrow cross-sections

Diagonal channel fan ML thanks to the unique design of the rotor and profiled guides is very efficient, and energy-saving, and at the same time is one of the quietest fans available on the market.

The device consists of three basic parts:
– base plates
– motor-impeller assembly with integrated connection box
– connection nozzles.

The whole is connected by means of two mounting clips. Thanks to this construction, the fans can be installed in any position. The rotor motor assembly can also be rotated at any angle. In limited spaces such as a suspended ceiling, this solution is very convenient. Cleaning and maintenance are also facilitated, as access to all elements does not require disassembly of ventilation ducts.

Diagonal rotor. Made of plastic. Profiled blades in order to keep as little turbulent flow as possible, placed on a conical hub, thanks to which air is directed to the most effective part of the blade.
