Powered Ventilators - Hybrid Powered Roof Extractors

Sudha Ventilating Systems Pvt. Ltd. (SVS), the leading manufacturer of latest technology wind driven turbo ventilators in India, proudly introduces the ecopower range of motorized roof extractors in technical collaboration with Edmonds, Australia. These are manufactured in a state–of-the-art unit at Ahmednagar, India, incorporating the worlds leading technology in motor design. ecopower powered roof ventilators are the world’s first true hybrid ventilators that will work in all conditions, even when there is no wind, to ensure a constant supply of fresh air. It combines natural ventilation with a computer controlled, very high efficiency electric motor in a single unit to ensure consistent air quality and guaranteed peak performance when you need it.


Benefits of ecopower

ecoPOWER® offers customers the following unique benefits:

  • Constant discharge when on power
  • Runs like a Wind Driven Turbo Ventilator when not on power
  • Low energy costs. Saves about 70% when compared with conventional motorised roof extractors
  • High efficiency ventilation at all times
  • Significantly lower noise and vibration levels than axial fan roof ventilators.
  • Advanced German EC motor technology.
  • Edmonds vertical vane vent technology for higher performance*.
  • Light weight
  • Simple installation. Guaranteed no-water leakage.
  • Single - phase power and low voltage (selected models) for easy electrical installation

Clean, fresh air. You’d think it would be something we all have the right to expect in our homes and work places and yet so often this isn’t the case. Inadequate ventilation can lead to the build up of heat, moisture and even potentially harmful chemicals in the air that we breathe inside our buildings every day.
