Blauberg Axis-Jet-CI, Axis-Jet-VI, Centro-Jet: high-performance jet and centrifugal fans for car parks and tunnels

Series of axial jet and centrifugal fans from Blauberg Ventilatoren designed for general purpose ventilation of underground and semi-opened parking, ventilation of tunnels, smoke extraction in case of a fire. The fans generate a high-speed and high-pressure directed air jet.

Blauberg Axis-Jet-CI, Axis-Jet-VI

The Axis-Jet axial jet fans are designed for continuous operation at air temperatures up to +55 °C, as well as for moving smoke and air mixtures with temperatures up to +400 °C for 120 minutes in smoke extraction mode. Designed for horizontal ceiling mounting by means of mounting brackets.

· Design

The fan casing is made of polymer coated steel. The fans are available in two casing versions: cylindrical (Axis-Jet-CI) and octagonal (Axis-Jet-VI). The Axis-Jet-VI model has a reduced height, a hinged hatch for electrical installation with captive bolts and a detachable middle part for maintenance. This solution greatly simplifies access to the electric motor with the impeller and unit maintenance. The fans have a sound insulation of mineral wool.

· Motor

The units are equipped with a three-phase asynchronous motor with a short-circuit rotor, rated for a voltage of 400 V (50 Hz). The motor design ensures operation of the fan in unidirectional and reversible modes. The motor ingress protection rating is IP55.

· Impeller

The dynamically balanced impeller is made of cast aluminium alloy (for fans of smoke extraction systems) or of glass-fibre reinforced polyamide (for fans of general industrial use). The reversible fans are equipped with a 100 % reversible two-directional impeller.

Blauberg Centro-Jet

The Centro-Jet induction centrifugal fans are designed for continuous operation at air temperatures up to +55 °C, as well as for moving smoke and air mixtures with temperatures up to +400 °C for 120 minutes in smoke extraction mode. Available in two modifications: one-speed and two-speed. Designed for horizontal ceiling mounting by means of mounting brackets.

· Design

The fan casing is made of polymer coated steel. Due to low height of the casing the fan is recommended for use in low-ceilinged rooms. The protecting grille on the intake side prevents ingress of foreign objects into the fan. A deflector is installed on the discharge side of the fan to ensure correct air flow distribution.

· Motor

Single- or double-speed 4-, 6- or 8-pole asynchronous motors are used. The motors are rated for 400 V power mains voltage and 50 Hz frequency. The motor ingress protection rating is IP55.

· Impeller

The impeller with backward curved steel blades.
