Permanent magnet motors running on high voltage direct current (DC) electricity with built in AC to DC conversion allowing them to run direct from single phase or three phase mains supplies. There are several suppliers of such motors.

So why choose OFAN ELECTRIC EC products?

EC technology is not new. Not to OFAN at least. We developed our first EC compact fan in 1965, 30 years before our competitors started to market their EC products and 15 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.

Centrifugal fans from OFAN are available with forward- or backward-curved blades. The low-noise centrifugal fans with forward-curved blades are also supplied with a scroll housing. The centrifugal fans with backward-curved blades are designed as free-wheeling fans and do not require a scroll housing. For the centrifugal fans with external rotor motors, the motor is positioned in the impeller, resulting in optimum cooling of the motor as well as an especially compact design. The entire product line is available in both AC and GreenTech EC technology.
