EC Fans – what are they?

EC Fans are here to stay; they are more efficient up to 90%, quieter and can be controlled by a digital fan controller unit. Let’s take a look how and why...

EC stands for Electronically Commutated – which means that it’s a DC motor with no brushes – making it brushless. The EC fan uses an optimised plastic flow axial impeller that is balanced specifically to reduce vibration, humming and buzzing. This state of the art technology enables the fan to be more efficient at even half speed it will use less than half the power than the AC motor.

Using the best of both technologies

The EC motor runs on DC voltage – but with a normal AC supply, because the EC motor incorporates a voltage transformation inside the motor – there is no need for a bulky transformer, which is required when running DC motor in an AC application.

To make room for an electronic PCB board which provides the power transformation AC to DC – the non rotating part of the EC motor (stator) has been cleverly extended and completely integrated within the motor, bringing the below benefits:

  • Super Energy savings : Lower power consumption & more efficiency than AC equivalent
  • More Control: Can be set-up for constant airflow or constant pressure applications, 100% speed controllable - not frequency dependant.
  • Lower motor running temperature: Giving you a longer lifetime than AC equivalent
  • Save you money: Low power consumption and higher quantities of air movement
  • Simplicity: Electronic & power transformation are completely integrated within the motor
  • Excellent performance: Speed can be driven up to 3600rpm, one EC fan replace multiple type of motors (2, 4 and 6 pole)
  • Easy setup: No complicated wiring and set-up with a EC fans have very little configuration

The Global leaders in ventilation technology - Systemair have released the new Revolution EC Vector Fans - making them the first to add this technology to their portfolio. 

The Revolution EC Vector fans are the best on the market, with millions invested in research and development, Systemair give a 5 year warranty.

These high quality and reliable German made EC fans are the cheapest to run available in sizes: 150mm - 781m³/h, 47dB @ 3m, 77W, 200mm - 1332m³/h, 50dB @ 3m, 117W and 250mm - 2077m³/h, 50dB @ 3m, 165W - changing the way you ventilate your grow space forever featuring:

  • Latest state of the art energy saving EC technology.
  • Single piece molded fan housing, no possibility of air leakages.
  • No humming, buzzing even on lower speeds.
  • Minimum fan speed can be altered from 0-100% with EC fan controller.
  • Maintenance free and reliable quality - made in Germany

To provide you with even further environmental control Systemairs GAS Digital EC Fan Controller will give you precise climate control. Using RTT (Reactive Temperature Technology) - should any sudden spikes in temperature occur the system is able to react and stabilize the temperature immediately, like wise for smaller rises the system will increase fan speed gradually - to the set temperatures you have programmed.

With its clean design and robust feel the GAS EC Controller features a easy to read LCD display - with fan speed and temperature dials which can display in Celsius and Fahrenheit, displays min and max temps and simply plugs directly into the Revolution EC Vector Fan - giving you ultimate environmental control at your finger tips.

The final EC product in the Revolution range is a optional Digital EC Fan Balancer - this will address and maintain negative air pressure in the grow environment.  Simply connected to the EC Controller the EC Balancer gives you control of both intake and out-take fans you can precisely balance your room perfectly.

So we hope that clears up any confusion on EC Fans - they are a real game changer - all Systemair products are available in store today!
