764m3/H High Pressure Blower Fan Dc Brushless Blower Fan 12v B
Insulation Class
DC technology is not new. Not to OFAN at least. We developed our
first EC compact fan in 2008, 10 years before our competitors
started to market their EC products and 8 years before
environmental protection was even an issue. In this time we have
improved, refined and extended the OFAN EC range into the
universal, high technology and reliable product that it is today.
This means that OFAN EC gives you high performance, silent speed
control and long life expectancy in a product which is the same
size as the old, power hungry AC products it replaces.

Permanent-magnet brushless DC motor within the rotor
The stator is driven by electronic switches (which replace the
Carbon brushes), controlled by a microcontroller.
Electronic system (hall effect sensor or software is used to
recognize the rotor position)
AC operated (230Volts Single phase or 380/480Volts 3phase, 50/60Hz)
