Airflow
Energy saving Electronically Commutated (EC) Fan Motor
Each 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 re-circulation. 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.
The in built EC fan control module allows for fan speed modulation from 15-100%, a standard AC fans modulating range
is typically 40-100% of full fan speed. The EC fan presents superior energy efficiency at full and 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. Standard voltage regulated (VR) fan speed
controllers offer a linear response. By comparison the 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.

Condenser Fans - AC
Axial fan assemblies with fingerproof grille and incorporating external rotor motor technology to provide highly accurate
discreet speed control. The fans offer maximum performance while keeping sound levels to a minimum. Electrical supply
