KBR/F Centrifugal Fans

The KBR/F casing is manufactured from double skinned 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/F fans have a swing-out door for easy inspection and service.

Tested according to EN 12101- 3. CE Certification according to EN 12101-3; 2002-06 through TÜV Süd.

The KBR/F fans use radial impeller with backward curved blades. These are made out of aluminium, dynamically balanced and paired with corresponding IEC motor with efficiency IE3 or EC motor.

High-temperature motors for temperature classification F400 (400°C/120 min).

Fans with AC motors have an integrated thermal protection with manual (electrical) reset, thermistor PTC for connection to a motor protection device.

Fans with EC motors have an integrated electronic thermal protection including locked-rotor protection and soft-start.

The AC motors can be controlled by 5-step, stepless speed regulator, D/Y switch or frequency converter.

EC motors with built-in potentiometer to adjust working point can be also controlled by external signal 0-10V.

The fans can be used indoor or with specific accessories also outdoor. Due to the mounted base frame the fan can stand on floor.
