The original idea for the inline duct fans was to combine the benefits of the

radial fan, high pressure and low sound level, with the straight-through airflow

of the axial fan.

In 1973 the first inline radial duct fan with an external rotor motor and

straight-through airflow was designed. Apart from high pressure and low sound

level, the main benefit was the ease installation.

Unlike the conven-

tional radial fans

the inline circular

duct fan is compact

and does not require

complicated duct

arrangements to install it.

One of the best inventions since the light bulb

T H E S T R A I G H T W AY

The straight way with the circular duct fan CK.

The revolutionary motor bracket with integratedguide plates that improves the capacity.

The external rotor motor with backward curved impeller blades is provided with approved motor protection.

The design of housing results in higher flowand with that an even higher efficiency.

European Patent 0625642.

Our self-closing louvre shutters have

a very low air low resistance.

For example; Resistance is 10 Pa

at 4 m/s air speed, 30 Pa at 6,5 m/s

and 50 Pa at 8,5 m/s.
