Contrary to many beliefs, Frost is a major inconvenience for Australian farmers and can result in significant losses if not correctly managed. Working alongside active and passive frost protection, our SIS (Selective Inverted Sink) fans are designed to sit in artificial or naturally occurring basins where frost accumulates. Utilizing its horizontal blades, the fan will extract stratified cold air from the ground, expelling it to a higher point in the atmosphere, where it will heat up and disperse!
More information regarding the science behind our fans and differing models can be seen on our website! (http://www.aavsupplies.com.au/farming-equipment/sis-frost-fan/)
