The CTL-4SK is a Limit Load centrifugal fan designed for inline installation. Its motor and bearings are mounted outside the airstream, ensuring reliable operation in high-temperature applications such as kitchen exhaust and smoke extraction. Its tubular construction allows for easy inline installation within the duct system, eliminating the need for additional elbows. The unit is also designed to accommodate the electric motor in four mounting positions and provides exceptional ease of maintenance, allowing the motor-shaft-impeller assembly to be removed without disconnecting the inlet and outlet ductwork.
