The EC RCD series of roof mounted down discharge fans incorporates very high efficiency electronically commutated DC motors with on board infinitely variable control modules. These fans are AC powered with control and power conversion electronics integrated into the motor. Motor speeds can be controlled with 0-10V input signal or 10K potentiometer.

The ability to control the speed at which the fan operates in response to real time ventilation demands is the basis of our energy saver range. Fan power consumption changes to the cube of speed reduction while air flow reduction stays proportional to reduced speed. This means that tailoring fan speed to meet exact air flow requirements has the potential to greatly reduce energy consumption through the removal redundant fan capacity.

Construction
Components are made from UV stabilised polymer, corrosion protected steel and fibreglass. All models are fitted with bird mesh as standard. Available in optional Colorbond™ colours.

Testing
Rated fan performance has been determined by testing to ISO 5801 : 2007. Fan sound data has been determined by testing to ISO 13347 : 2004.

Wiring diagrams and latest data
Refer to the latest product datasheet for individual model wiring instructions, data and specifications. Datasheets are available from our electronic selection software FansSelect.
