The Turbo125 insertion tube fan draws off used air through a 125mm exhaust air duct. It's capacity is construed for a room up to 15sqm (ceiling height 2.50m).
For the Turbo125 insertion tube fan completely consists of plastic, there's no need for an earthing, when assembling it. Therefore a cord with two cables is totally enough.
Before mounting it, you can decide between two possible power levels:
LOW = 170m3/h (the brown cable of the cord meets the black cableof the fan - see picture)
HIGH = 210m3/h (the brown cable of the cord meets the brown cable of the fan - see picture)
The blue cable of the cord always meets the white cableof the fan.

You get the accordant cord at Udopea, too.

The tube fan is about 23 cm long.
