Sukup's Axial Fans and Heaters are engineered to provide efficient, reliable airflow and even heat distribution for maintaining grain quality.

Sukup's Axial Fans are designed to provide efficient airflow for aeration or in-bin drying, particularly suitable for lower static pressures. These fans feature cast aluminum blades engineered for high performance at 3,500 RPM, providing vibration-free operation due to precision balancing. The design includes unique square end plates that maintain the housing's roundness and close tip clearance to enhance airflow by preventing air from blowing back between the blade and housing.

Sukup Axial Heaters are equipped with several safety features to increase reliability, including pressure relief valves on piping, a stainless steel flame sensor that shuts off gas if the flame is not present, and spring-loaded solenoids that close automatically when power is lost. These heaters are designed to work efficiently with Sukup fans at lower static pressures. The design includes a service door for easy access and a sight glass for inspection while operating.

Sukup's Axial Fans & Heaters form a powerful duo in grain handling systems. Their combined functionality helps to preserve grain quality, enhance longevity, and reduce the risk of loss due to spoilage.
