Ostberg Americas, Inc. Fan DFE 146-S2

DF is a range of compact double inlet radial fans. They have high capacity and low sound levels. They are ideal for use in heat exchangers, dehumidifiers and air cleaners. The forward curved impellers are driven directly by a ball bearing mounted external rotor induction motor. The motor is placed in the air stream for maximum cooling. This makes voltage regulation possible from 0-100%. The motor is maintenance free and has a built in thermal protector as standard. The DF fans are manufactured using galvanized sheet metal.
