KBT Centrifugal Fans
Powerful and efficient exhaust fans for medium temperatures up to 120°C
Up to 120°C medium temperature, continuous operation
Acoustic and thermal insulation 50 mm
Excellent for commercial kitchens and process exhaust systems
Easy to service and maintain due to the swing-out inspection door and drain plug
Reliability
The KBT fans are designed for reliable, continuous use with medium temperatures up to 120°C.
The combination of reliable casing and motor construction ensure to minimize the need for maintenance of the fans and allows long continuous operation.
High performance
High-performance impeller together with highly efficient motor are designed to ensure high-level performance with minimum power consumption and maximum efficiency.
Low noise
Casing of KBT models have perfect acoustic/thermal insulation capacity. In addition, anti-vibration dampers and flexible connections allows to reduce noise and vibration transfer to the duct system.
Easy maintenance
Integrated protection plate prevents escaping grease or oil. Integrated drain plug for liquids allows to organise a natural drain. A dedicated swing-out maintenance door allows quick and easy maintenance of the fan.

Construction
The KBT casing is manufactured from double skinned galvanised sheet steel and is insulated with 50 mm mineral wool.
The fan motor is mounted on a swing-out door outside of the airstream and covered by weather protection.
Casing design includes integrated protection plate to prevent escaping grease or oil and integrated drain plug for draining liquids.
Impeller
The KBT fans use lightweight radial impellers with forward curved blades. These are manufactured from galvanised steel, dynamically balanced and paired with corresponding motor.
Motor
Depends on type, KBT fans are equipped with IEC motors (efficiency class IE3) or EC motor.
Models with EC motors are suitable for operation at 50Hz and 60Hz.
Motor protection
Models with AC motors have integrated thermal contacts TK or integrated thermistors PTC with leads for connection to an external motor protection device.
Models with EC motors have integrated electronic thermal protection including locked-rotor protection and soft-start.
Control
Models with AC motor can be controlled by frequency converter.
Models with EC motor equipped with built-in potentiometer to adjust working point, can be controlled by external signal 0-10V.
Installation
KBT fans can be used indoor or outdoor. Due to the integrated base frame the fan can stand on the floor or on the wall mounting brackets.
Base frame equipped with anti-vibration dampers to prevent vibration transfer from the fan to the construction elements. For preventing vibration to the ducts it is recommended to use flexible connections.
