Fans are the key to successful drying or aeration systems, which is why Sukup puts great effort into designing and manufacturing the best fans possible. Sukup's Centrifugal Fans are designed to provide efficient and reliable aeration, essential for maintaining the quality and integrity of the grain.

The centrifugal fans from Sukup's grain handling solutions are known for their powerful and efficient airflow. They are engineered to deliver airflow through the grain, ensuring that it remains dry and cool to prevent spoilage.

All Sukup fans are factory-tested prior to shipment in order to ensure that our customers are getting a top-quality product that works properly from day one. Fans are tested for smoothness, motor performance, and general operation. Additionally, Sukup offers a two-year limited warranty you can depend on.

Sukup’s Centrifugal Fans provide effective aeration and temperature control, critical for preserving the quality of grain. Sukup's commitment to quality and innovation is evident in centrifugal fans, offering producers efficient, reliable solutions.

Standard Features

  • Sukup fan housings, control boxes and motor mounts are made of heavy-duty galvanized steel to resist rust and stand up to the elements
  • Plated screen guard over air intake provides for safe operation
  • Curved, spun inlet venturi improves efficiency
  • Adjustable leveling legs on single inlet fans allow for easy leveling and support while giving more flexibility for adjusting to inconsistencies in concrete pads
  • Exclusive lip easily connects the fan to the heater or transition to form an airtight seal

Centrifugal Fan Blade

  • Sukup’s special airfoil blades move more air due to the backward-curved, non-overloading design
  • Fan wheels are statically and dynamically balanced for smooth, trouble-free operation

Centrifugal Controls

  • Sukup engineers test motor amperage and temperature under long-term, maximum-load conditions to ensure the motors will stand up under tough operating conditions
  • Controls include:
    • Magnetic starter
    • Overload relay
    • Start-stop buttons
    • 115v circuit to interlock heater with fan (7.5 – 50 HP 1750 RPM)
  • Direct motor drive is standard for greater efficiency and less maintenance
  • Integral motor mounts
  • Available models: 1 phase, 230 volt; 3 phase, 230 volt; 3 phase, 460 volt
  • 50 Hz and other voltages available upon request

Sukup Transitions

  • Galvanized steel ensures long life
  • All seams overlap to prevent air leakage
  • Units bolt together easily
  • Special “nutserts” are attached directly to sheet metal, so only one wrench is needed to tighten bolts for assembly

Sukup 3500 RPM Fans

  • Sukup offers a full line of high speed (3500 RPM) centrifugal fans
  • Ideal for deep grain depths, aerating small grains, and in situations where static pressure is high, as in commercial uses
  • Totally enclosed motors

Dual Inlet Fans

  • Dual inlet fans are available for 30 HP, 40 HP, and 50 HP 1750 RPM fans
  • The double-blade design blows away comparable single-blade fans in airflow and efficiency
  • The double inlet pulls air over the motor, completely utilizing motor heat in the process
  • Downstream heaters for dual inlet fans are available for high-capacity in-bin drying
  • Engine-driven dual inlet fans are also available

Centrifugal In-line Fans

  • Sukup In-Line Fans feature a centrifugal fan wheel built into an axial housing
  • 3500 rpm motor is specially engineered for high-performance Sukup blades to ensure maximum airflow
  • Ideal for higher static pressures found with small grains and higher grain depths
  • CSA models available in 18”, 24”, and 28” sizes

Product Accessories

  • Optional transitions are available that fit between bin stiffeners
  • Optional hanging kits
  • Dual burner controls with optional gauges allow control of multiple heaters from one control box, ensuring they are cycling on and off together for even heat
  • The deluxe control box includes a static pressure gauge and thermometer, along with the temperature controller
Product Features
  • Huck Bolt Fasteners on Housings
  • Highest Airflows in Industry
  • Leveling Legs To Reduce Vibrations
