Series Blauberg Axis-Jet-CI

Axial jet fans for ventilation of covered parking. Temperatures of the transported medium: in continuous operation up to +55 °C in smoke extraction mode: 300-400 °C – 2 hrs.

Use

The Axis-Jet-CI axial fans are designed for general purpose ventilation of underground and semiopened parking, ventilation of tunnels, smoke extraction in case of fire as a part of smoke extract system. The fans generate a high-speed and high-pressure directed air jet.
Temperatures of the transported medium: in continuous operation up to +55 °C; in smoke extraction mode: 300 °C/2 hrs and 400 °C/2 hrs
The fans with a fire resistance class of 200 °C/2 hours can be produced on request.

Design

The casing of the fan is made of polymer coated steel.
The casing includes inner brackets for motor fixation. These brackets act as directing vanes and distribute air flow uniformly, thus increasing aerodynamic performances of the fan. The fan has a sound insulation of mineral wool.

Mounting

The Axis-Jet-CI fans are designed for horizontal ceiling mounting and fixation by means of the supplied fixing brackets attached to the fan casing.

Impeller

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

Modifications

Unidirectional single-speed type (U)
Unidirectional double-speed type (U)
Reversible single-speed (R)
Reversible double-speed (R)

Motor

Three-phase asynchronous short-circuit rotor motor is installed inside the fan casing. Motor ingress protection rating is IP55. The motor design ensures operation of the fan in the smoke extract systems and/or general ventilation systems in unidirectional and reversible modes. The motors are designed for 400 V mains voltage and 50 Hz mains frequency.
