Kruger Fan KAT series

KAT Series - Double Inlet Centrifugal Fans - Forward Curved

The KAT series is DIDW centrifugal fan with forward curved (FC) impellers. The fans are suitable for supply and exhaust applications in commercial, process and industrial HVAC systems. Ranges KAT-9/7 to KAT 18-18 are AMCA certified to Air, Sound and FEG.

The KAT series is available in Type S and C.

KAT series is also available in twin fan version with two double inlet fans mounted on the same shaft.

KAT fans are operated at relatively low speeds and are used to deliver large air volumes against relatively low static pressures. The inherently light construction of the forward curved wheel does not permit it to be operated at speeds needed to generate high static pressure.

The typical application range of this type of fan is from 30 to 80% wide open airflow. Selecting an operating point below approximately 30% wide open may place the fan in an area of instability. Similarly, an operating point beyond 80% wide open typically produces noise and inefficiency.

The maximum static efficiency is from approximately 50 to 65% and occurs just to the right of the maximum static-pressure point on the fan performance curve.
