TURBINE EXHAUST FANS
Why pay for ventilation when Mother Nature will do the work for you?
A properly designed gravity opening will provide ventilation due to stack effect, but by harnessing the wind, ventilation can be improved by 600% or more! Antiquated "doghouse" style gravity openings are susceptible to wind direction and can actuallycause downdraft shutting off exhaust ventilation. With the Hurrican wind driven turbine ventilator, the wind strikes the verical vanes causing the head to rotate. The rotating action generates a powerful area of low pressure causing additional air to be exhausted from the building.

Are you aware of the hidden costs of exhaust fans? The immediate reaction by facility owners to improve ventilation is to add some exhaust fans. Exhaust fans will move air to be sure, but when you stop to think about the cost of exhaust fans is it really an effective approach? First you have the fan equipment cost, then you have the structural modification costs to handle the heavy weight of the fan, then you have the motor starter costs, electrical operating costs and finally you have frequent maintenance costs.
ECOPOWER HYBRID VENTILATOR
The Eco Power utilizes an electronic commutating (EC) motor installed in the head of the ventilator to enable motorized boost during perios of low wind speed or special ventilation needs. The motor can be activated by any digital measure, humidity, gas concentration level, etc. The standard product is controlled manually by a switch (not included). Unlike previous attempts to produce a hybrid mechanical / wind vent, ecopower has no motor and fan blade in the throat of the vent. This is extremely important! Research using AS4740:2000 (performance of natural ventilators) has shown clearly that any obstruction in the throat of a wind driven ventilator will greatly decrease vent performance under wind load. The level of flow reduction can be 40% or greater. Also, axial fans located in the throat of wind vents can produce significant noise levels.

H900: 36" 7331 cfm @ 10 mph wind
Eco Power is one large direct drive centrifical fan. The bearing system of the motor becomes the bearing system of the ventilator. This means that the vent can be free spinning under wind load or power activated as conditions require. The use of an EC motor ensures that the best energy efficiency features available are factored into the product design.
