In-line axial fans, VO and VOK series

The VO series In-line fans have equally sectioned cylinder shape, which makes it

suitable to be fitted in air ducts or vent openings, while the VOK series have an outer

rim of the cylinder making it ideal for connecting air ducts.


The VO and VOK series come with or without back shutter

to prevent inflow of cold air and insects when the fan is switched off.


The noiseless and highly efficient electric motors of our ventilators are sealed for life

 and are totally maintenance free. The embedded Long Life double capsulated bearings

guarantee no quibble and smooth operation for over 30 000 hours of continuous usage.


The body, the turbine, and the back shutter are manufactured from  aluminum alloy or

glass-filled Polyamide.


The body of the motor is manufactured from aluminum or a heat-resistant

material which guarantees efficient cooling and higher fire safety.


The IP 44-degree protection allows the ventilator to operate in conditions of high

humidity and aggressive environment. 

The in-line axial fans can be mounted in or between air ducts, in walls, ceilings, suspending ceilings.

They are perfect  to be used as extractor fans, as well as heat exangers between neighboring premises.
