PTO-Driven Frost Fans

AGI’s PTO-driven frost fans provide a cost-effective, flexible solution for targeted frost protection. Powered directly by your tractor’s Power Take-Off (PTO), these mobile units can be positioned exactly where protection is needed — making them ideal for low-lying areas and frost-prone zones.

Designed for ease of use and reliable performance, they deliver strong airflow to displace cold air and protect a wide range of crops. Whether used as a standalone solution or to supplement existing systems, PTO-driven fans offer an efficient way to improve coverage and reduce frost risk without significant capital investment.

PAIR WITH TARGETED HEAT SOLUTIONS

Strengthen your frost protection with targeted heating

For more extreme conditions, AGI’s PTO-driven frost fans can be paired with return-stack heaters to enhance protection. These systems deliver targeted heat in low-lying areas where cold air settles, improving thermal lift and reducing frost risk.

By combining airflow with controlled heat, growers can prevent cold air accumulation and protect crops more effectively. AGI also offers customised, automated heating solutions that can be integrated with AGI LIVE to suit your specific requirements.
