Polycarbonate Aeration duct

Grainair Poly Air Ducts

•All our fittings are Poly carbonate•Bell and spigot design•Each section simply slides together•Aeration duct from 600 millimetre to 300 millimetres depending on application

Aeration Fans

• Grainair Fans are designed to produce a large amount of air at

high pressures• Grainair fans are designed tough - so tough in fact

that we offer a 5 year warranty

Diesel Powered Fans

• We offer diesel powered fans for use where electricity is unavailable

Aeration Control

• The ability to control the fans automatically is an important function of our aeration system

• Grainair control systems are designed to continually look for cooler air

• Working through a series of step downs we are able to cool the grain mass in a few short weeks and maintain an inherent ability to control the fans in a wide variant

of weather conditions• Grainair systems have a built in “Set and

forget” function
