Hybrid Ventilator

CSR Edmonds manufacturer of the Hurricane® industrial ventilator, have developed a patented hybrid vent design that uses electronic commutating motor technology located in the top of the Hurricane® Ventilator.
The design allows the vent to spin freely under wind load and provide the same exhaust rate as the traditional Hurricane vent. The free area of the throat is NOT impeded, unlike current vent fan combinations. When required the vent can be powered which provides a huge boost to the flow rate, at an extraordinarily high efficiency; 110 m3hrwatt of energy - far more energy efficient than any conventional powered fan.
The guaranteed exhaust rate regardless of wind speed or 'stack effect' can be controlled by digital measurement of a range of physical properties or chemical entities including temperature, humidity, carbon dioxide, etc.
With a very low operational noise, the ecoPower is ideal for use in homes, offices or factories.
