| Hurricane™ FAQs

By natural convection, the hot air from inside the building will rise and go through the turbine creating a stack effect thus exhausting the hot air, making the turbine turn without any external wind.

How much does one 36” Hurricane™ Turbine weigh?

It only weighs 18.1 kg or 39.9 lbs.

What kind of maintenance is required?

Almost none! Depending on your environment, an inspection once a year should be enough to verify that everything is tight.

How many cubic feet of air per minute can each Hurricane™ exhaust?

On a calm day with an outside wind of 6 km/hr a H900 (36”) Hurricane will exhaust about 3305 CFM. A wind speed of 16km/hr or higher the H900 will exhaust 7331 CFM. Typical wind speeds range between these two points. Consult your local historical weather data for more details.

What is the warranty included with the purchase of each Hurricane™ turbine?

It comes with a 15 year limited warranty.

Is a fresh air intake required with the installation of the Hurricane™?

Depending on your building, there may be enough existing air intake to provide fresh air. If additional fresh air is required, the most economical way to achieve this is by installing louvers.

Will Envira-North Systems Ltd install the Hurricane™ turbines in my facility?

No, your roofing company is better equipped to deal with your roof. We can provide detailed instructions and guidance to contractors or recommend someone in your area who has previous experience with the applications.
