specifications

The fan and heater is the most important part of any drying system. That's why it's imperative that you are aware of the many superior features of the five models of U-Series fan-heater units from Farm Fans...
• Performance that delivers 11,000 to 26,000 CFM at 1" Static Pressure.
• A choice of units ranging from 2,000,000 to 4,000,000 BTU per hour.
• High efficiency vane axial fan, with guide vanes and inlet venturi for more air with less horsepower.
• One-piece cast aluminum propeller with airfoil design blades, dynamically balanced, mounted by taper lock bushing.
• Star Fire burner provides maximum fuel efficiency.
• Heavy gauge steel housing to insure minimum blade tip clearance for high efficiency operation.
• Magnetic motor control for maximum motor protection and motor overload protected...running load and locked rotor.
• Fail-safe ignition for full electric ignition heater control circuit.
• Safety control circuit with purge cycle, automatic high-limit projection and burner shutdown on flame failure.
• Available in single phase or three phase.
• All units available for liquid propane (with vaporizer) (LP), propane vapor (PV) or natural gas (N). (NOTE: Hi-Lo Fire burner control available on LP units; cycles from high to low fire by thermostat control.)

Applications

The U-Series Fans offer a full range or air flow rates and heater capacities for all types of bin drying systems including combination drying. In addition, U-Series Fans complement the new high-speed in-bin systems by providing supplemental heat and air to completely dry the grain.

Construction

Unitized construction means that all elements are contained in one housing, plus weather-tight cabinet construction.

Reliability

U-Series Fans from Farm Fans have withstood the test of time, boasting over 25 years of proven performance and reliability.

Starfire Burner

The unique Starfire Burner features perfectly balanced steel vanes welded to a cast-iron burner for evenly-spread flames and maximum fuel efficiency. It features a heavy cast venturi and burner cup which combine with diverging vanes for uniform heating of the drying air to permit the rapid removal of excess grain moisture.
