Energy saving Electronically Commutated (EC) Fan Motor
Each 800 mm diameter fan incorporates on board electronics with AC / DC conversion and inverter driven DC motor
control to offer unparalleled high efficiency levels combined with smooth step-less speed control and quiet operation.
Sickle blades reduce air turbulence to minimise sound levels and power consumption whilst maximising performance.
The long bell mouth design provides improved aerodynamics, up to 10% more air movement, and an extended vertical
throw of air to reduce the chance of air recirculation. As standard the enclosure is complete with an integral finger proof
grille.
The fans offer maximum airflow performance while keeping sound levels to a minimum.
A mains EMC filter is fitted when the standard EC fan option is selected with the unit. The filter is designed for
convenient mains connection within the bus bar chamber. The in built EC fan control module allows for fan speed
modulation from 15 -100%, an AC fan’s modulating range is typically 40-100% of full fan speed.
The EC fan presents superior energy efficiency at reduced fan speed compared to the equivalent AC fan motor, offering
efficiency savings anywhere between 30 to 100% compared with an AC fan. Fan speeds are factory set depending on
sound level variant. Voltage regulated (VR) fan speed controllers offer a linear response. By comparison the standard
EC fan is adjusted on demand via the unit microprocessor with precision, offering substantial energy savings. The
following illustration shows a comparison of the typical power input required by each method.
