Ventilation Principle from Nature’s Wisdom,
The Cone Shaped Guide Plates
Impact between exterior wind and guide plate creating combine effects of wind and pressure differentials resulting chimney effect to induct air exhaustion.
Return air is increased by 14% in newly designed plastic stationary ventilator by additional guide plate to rid vortex effect.
Durability of Engineering Plastic
Newly designed plastic stationary ventilator is built with polyethylene to ensure more durability against impacts, wear and tear caused by environmental exposures and noise caused by rain and hail.
