Powerful smoke extraction

The smoke extract units KBR/F are used in case of fire to extract smoke gases and also during normal working conditions for temperature up to 200°C continuously.

Hard-wearing design

The KBR casing is manufactured from doubleskinned galvanised sheet steel and is insulated with 50 mm mineral wool.

Performance

High performance impeller together with high efficient motors are designed to ensure high-level performance to minimize power consumption and maximize efficiency.

Construction

The KBR/F 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/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.

Impeller

The KBR/F 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.

Motor

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

Motor protection

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

Control

The 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.
