Tech specs

Features

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.
