LOREN COOK COMPANY’s Tubular Centrifugal Inline fans are available in direct drive sizes from 60 to 165, and belt drive sizes from 60 to 490 in both standard and heavy duty construction. TCN performance ranges from 50 CFM to 52,000 CFM and static pressures up to 5 inches. With a full range of mounting options and accessories, the TCN is an effective alternative for round duct installations requiring high flow rates at low to moderate static pressures.
  • Integral inlet and outlet flanges are provided for easy duct connection.
  • A large access door is standard on direct drive models. This large access door allows for removal of the motor and the wheel without removing the fan from the ductwork.
  • An inspection door is standard on belt drive models. It is oriented 180o from the motor providing access to the fan for cleaning and inspection.
  • On belt drive models, the optional access door allows removal of the bearings, shaft, and wheel for cleaning and maintenance without removing the fan from the ductwork.
  • Bearings and drives are isolated from the airstream. Removable bearing and drive covers provide easy access for inspection and service.
  • Extended lubrication lines are standard on belt drive units for ease in bearing maintenance.
