Axial smoke extraction fan Blauberg Axis-Jet, Fire resistance, Smoke extract system

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 the fire resistance rating 200 °C/2 hrs can be manufactured on special request.Functionality. Power. Efficiency.

The casing of the Axis-Jet fan is made of polymer coated steel. The fans are available in two casing versions: cylindrical and octagonal. 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. The fan in an octagonal casing Axis-Jet-VI has a reduced height, a hinged hatch for electrical installation with captive bolts and a detachable middle part for maintenance.

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

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.

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.

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