Australia and New Zealand’s Most Efficient Frost Fans & Wind Machines
Drying | Ventilation | Cooling | Efficiency | Portability | Durability
AIM offer two models of portable frost fans to cover a range of frost protection requirements.
For applications where noise and efficiency are key considerations, the 250H is a great option. A fuel burn of just 5L per hour makes it one of the lowest cost-of-ownership frost protection solutions.
Where high performance is required, the 650H offers comparable coverage area to fixed tower fan options while maintaining the same portability advantage that Tow and Blow is renowned for.
The use of a ducted fan design reduces cavitation at the tips of the fan blades which is one of the largest sources of noise and energy loss in a fan blade. Having a shroud around the fan allows the use of correcting vanes, minimising turbulence in the airflow, hence adding significant range to the fan's coverage when compared with an uncorrected airstream. Combined with the direct-drive of the motor to the fan shaft the Tow and Blow design delivers maximum performance in a very compact package.

Commonly Asked Frost Fan Questions
Frost fans are essential for protecting your crops. They utilise warmer air from a higher layer to protect the crop from potential frost damage. The frost fan is positioned with a slight downward angle to bring down the inversion layer to ground level, safeguarding the crop from potential frost damage.
Frost fans can generate some noise as they are moving air constantly moving heat onto the crops. In a farm setting the noise isn’t something to worry about.
Yes, a fan can help prevent frost damage by circulating air and disrupting the formation of temperature inversions. This helps to mitigate the risk of frost settling on plants, protecting them from potential harm during cold conditions.
