Turbine ventilators remove the radiant heat and stale air from buildings that builds up under the roof.
They turn with external wind and convection, requiring no electrical power to operate, silently
removing the stale, humid, warm air and replacing it with cooler, fresh air from below.
They leave a more pleasant atmosphere and are highly cost effective.
They are supplied with a 3-year warranty when installed by an approved installer.
The quantity and size required are calculated using design constants derived from tests conducted by the C.S.I.R., other independent laboratories and ourselves.
