KBR 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
Reliability
The KBR box fans are designed for reliable, continuous use with medium temperatures up to 120°C.
The combination of reliable casing and motor construction ensure minimize the need for maintenance of the fans and allows long continuous operation.
Performance
High performance impeller together with high efficient motors are designed to ensure high-level performance to minimize power consumption and maximize efficiency.
Noise
The casing of KBR models have perfect acoustic and thermal insulation capacity.
Construction
The KBR casing is manufactured from doubleskinned galvanised sheet steel and is insulated with 50 mm mineral wool.
The fan is isolated from the casing via connectors and anti-vibration dampers are incorporated into the base frame. Standard is that the motor is outside the air stream.
The KBR fans have a swing-out door for easy inspection and service.
Impeller
The KBR fans use radial impeller with backward curved blades. These are made out of galvanised steel, dynamically balanced and paired with corresponding IEC motor with efficiency IE3 or EC motor.
Motor
Depending on the type, KBR fans are equipped with AC or EC external rotor motors. Motors are suitable for 50Hz and 60Hz.
Motor protection
Depending on the type, AC motors have an integrated thermal protection with manual (electrical) reset, prewired integral thermocontact TK or thermistor PTC with leads to a motor protection device.
Fans with EC motors have an integrated electronic thermal protection including locked-rotor protection and soft-start.
Control
EC motors with built-in potentiometer to adjust working point can be also controlled by external signal 0-10V.
EC motors, depending on the type are also equipped with ModBus communication or alarm signal.
AC motors can be controlled by 5-step, stepless speed regulator, D/Y switch or frequency converter.
Installation
The fans can be used indoor or with specific accessories also outdoor. Due to the mounted base frame the fan can stand on floor. For preventing vibration to the duct is recommended to use flexible connection.
