AC Centrifugal ventilators: totally vibration-free operation.

The standard version of these motors is 230V 50Hz. All motors have (class C) bearings with pre-compressed lubricating grease to last the entire lifespan of the bearing. Standard motors are winding class B.

The motor is suspended by rubber vibration isolators on both sides. This means any vibrations created at particular speed settings are not transmitted to the ventilator casing. Your guarantee of totally vibration-free operation. All fans have forward-curving  blades and are made of galvanised steel. Fans and motors are in mutual balance, both statically and dynamically.  All motors can be regulated by thyristor or transformer.
