Description
APPLICATION MODIFICATIONS
  • JAF jet 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.
  • Unidirectional single-speed type (U).
  • Unidirectional double-speed type (U).
  • Reversible single-speed (R).
  • Reversible double-speed (R).
DESIGN MOTOR
  • The casing of the JAF fan is made of polymer coated steel.
  • The fans are available in two casing versions: cylindrical and octagonal.
  • The fan in an octagonal casing has a reduced height, a hinged hatch for electrical installation with captive bolts and a detachable middle part for maintenance.
  • 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.
  • 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.
IMPELLER MOUNTING
  • 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.
  • JAF fans are designed for horizontal ceiling mounting and fixation by means of the supplied fixing brackets attached to the fan casing.
The fans with the fire resistance limit 200 °C/2 h can be manufactured on special request.
