Tube Axial Fan

Longwell’s tube axial fans are engineered for heavy-duty industrial ventilation and other rigorous applications. They are especially suitable for paint and powder coating booths. With a variety of standard diameters and airflow ratings, we also offer custom sizes and specifications upon request. All Longwell fans are fully assembled, factory tested, and come with a one-year manufacturer’s warranty.

Construction:

  • Totally Enclosed Fan Cooled Motors Mounted Outside the Airstream.
  • Single Phase Motors: 115 or 220 Volts.
  • Three Phase Motors: 208, 230, or 460 Volts.
  • Heavy Duty Mounting Flanges.
  • Non-Sparking Polypropylene Blade with Aluminum Hub.
  • Dual Pillow Block Bearings.
  • Remote Grease Fittings for Easy Maintenance.
  • Durable Powder Coated Finish.

Important Notes:

  • Motor Starter, VFD, or Control Package is Required.
  • Single Phase Motors Operate at One Speed and Require a Motor Starter.
  • Adjustable Fan Speed Requires a Three Phase Motor and VFD.
Longwell Tube Axial Fans are designed to move large amounts of air through ducts or confined spaces, providing effective ventilation in industrial and commercial facilities. Their cylindrical housing design minimizes turbulence and pressure loss.
These fans combine high-efficiency impellers with precision-balanced rotors to ensure quiet and smooth operation. Longwell tube axial fans are ideal for exhaust, cooling, and general ventilation applications.
