Performance

The ecopower has been developed to provide the highest levels of performance. When tested against comparable sized axial fans, ecopower has demonstrated extraordinary energy efficiency under power load, requiring up to 76% less power to maintain the same extraction rate.

The ecopower also operates at a new level of quietness running at levels up to 14.5dB(A) lower than traditional mechanical axial fans.

Product Exhaust Rate [m³ / hr] Power [W] Noise @ 3m [dB(A)]
300mm, 2p, 1θ-Axial fan 2160 160 55
EP400 2400 68 46
Improvement   63% lower 9 dB(A) lower
450mm, 4p, 1θ-Axial fan 4280 480 60
EP600 4280 116 49
Improvement   76% lower 11dB(A) lower
630mm, 6p, 3θ-Axial fan 9000 1000 60
EP900 10000 260 45.5
Improvement   76% lower 14.5 dB(A) lower

 

Energy Savings

The example below demonstrates the running cost savings and CO2 emission reductions available in a typical 10 unit installation compared to mechanical axial vents. In this example energy and greenhouse gas reductions of 75% are achieved, this equates to a $1,763 annual energy saving and an annual greenhouse gas emissions reduction of 12.3 tonnes based on the use of coal fired electricity.

The ecopower not only uses less power in powered mode, but can also run for a shorter period due to the availability of continuous ventilation in natural mode. This allows for similar air change rates over a 24 hour period compared to the mechanical unit, which must run for a longer period.
