Fans and heaters

1301

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.

1302

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
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 cannot be used with heaters due to their design.

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.

Vane Axial Downstream Heaters
Whether natural air-drying grain or heat drying, all GSI “drying” fans have the option of adding a heater. With capacities up to 3.0 million BTU/hr., our vane axial fan and heater combination provides the very best in high capacity grain drying. Vane axial heaters are available in 18” through 28” diameter, liquid propane, propane vapor or natural gas models.

Centrifugal Downstream Heaters
GSI’s downwind centrifugal burner is a high efficiency option to compliment our high capacity centrifugal fans. Specially designed burners are adjustable for uniform heating temperatures with a choice of liquid propane, propane vapor or natural gas. Available for GSI’s 1750 RPM (10-40 HP) centrifugal models, the downwind centrifugal burner is capable of capacities up to 4.2 million BTU/hr.
