Axial fan VLB

with asynchronous motorsteelcast aluminum

Axial fans with impellers fitted with hubs that allow the blade angle to be changed smoothly during fan operation. The impellers are additionally equipped with special low-noise blades, which is a definite advantage in an open discharge system. They generate a lower noise level. By changing the blade angle, the fan performance is adjusted.
