    Fans and Heaters

    GSI manufactures a complete line of aeration and grain conditioning systems to help maintain grain quality. Choose from a variety of high efficiency vane axial, centifugal and inline centrifugal fans and heaters, all with features designed to reduce cost and boost performance.


    Vane Axial Fans

    Vane Axial Fans
    For application requiring high airflow at static pressures below 6”, GSI offers vane axial fans in 12” diameter (1 hp) through 28” diameter (15 hp). Vane axial fans 18” and smaller use cast aluminum blades. Vane axial fans 24” through 28” use durable composite airfoil blades that are lightweight for easy starting and function well in this type of environment.

    The 12” through 28” (1-15 HP) units feature a 3450 RPM motor for increased fan performance and energy efficiency. Close fan blade tip clearance and straightening vanes provide maximum air flow and reduced turbulence to ensure smooth and consistent airflow.

    All 24” and 28” vane axial fans also include an inlet venturi which funnels air more efficiently into the fan. Venturis and grill guards are corrosion-resistant painted for longer life.

    Inline Centrifugal Fans

    Inline Centrifugal Fans
    Aeration jobs at high static such as with milo, wheat or rape seed require special consideration. Aerating tall hopper tanks presents another challenge. The inline centrifugal fan is designed to handle both of these applications effectively.

    Suited for higher static pressures, beyond the performance range of vane axial fans, the inline centrifugal fan offers higher static pressure capabilities to a 1750 rpm centrifugal fan at a lower cost.

    Inline centrifugal fans make less noise than vane axial fans, and 1750 rpm centrifugal fans are even quieter.

    Inline Centrifugals can not be used with heaters due to their design.

    Centrifugal Fans

    Centrifugal Fans
    1750 RPM Centrifugal Fan
    Built with a heavy galvanized steel, scroll-type housing and inverted inlet venturi. A non-overloading backward-inclined airfoil wheel provides high airflow with a long motor life. These fans operate at a very low noise level and are designed to accommodate a variety of heaters for use on drying bins where higher capacities are required. Models are available from 5 - 50 HP with static pressures up to 11”.

    3500 RPM Centrifugal Fan
    GSI also manufactures a 3500 RPM centrifugal fan designed to operate in static pressures up to 22”. These fans are used primarily with tall tanks or small grains tanks with high resistance to airflow.
