FACT SHEET

RiteFlite ventilators are unique, they are the only ventilators in the world with blades that rotate in both directions, and when viewed externally, turning clockwise they expel the stale air due to pressure differences between an enclosed area and externally. When pressure is equalized they rotate anti clockwise introducing fresh air, therefore, importantly keeping a balance between the enclosed area and the air outside, and most importantly, they are noiseless.

The Patented wing tipped blades act as a venturi and attract the majority of air rushing past the ventilators drawing the fresh air inward where it is required. Most static vents, Terracotta, wire mesh, etc., loose the bulk of air travelling past them, what little air enters is generally lost up the cavity. RiteFlite units are installed with a short tube to breach the cavity directing the bulk of the air to sub floor area where it will have the most effect. This is all achieved without energy other than pressure differences and wind.

Mechanical units and solar powered type ventilators are noisy, and have to rely on electrical energy and time clocks, which in many cases are set incorrectly operating when the weather is fine and off in inclement weather when needed, or there is no solar energy available (cloudy days or night time). Mechanical units can also be a problem if used in areas where the strata is clay and foundations with brick and stone footings, which can result in strata shrinkage and foundation settlement causing wall cracking throughout the residence. RiteFlite ventilators increase their efficiency as the weather gets worse which is what is needed, keeping a balance between the sub floor area and the external air 

For comparison, a standard Terracotta vent has a static air intake area of around 4,000mm² a standard wire mesh vent around 7,000mm² compared to a RiteFlite ventilator 160mm diameter around 24,000mm² and the 240mm diameter 54,000mm² when the blades begin to rotate, the intake increases dramatically, the increase varies upon pressure differences and wind factor.

RiteFlite ventilators are designed and installed to comply with A.S.3660.1 for ventilation.
