Description
Description
APPLICATION MODIFICATIONS
  • JAF jet axial fans are designed for general purpose ventilation of underground and semiopened parkings, 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
  • JAF casing has a tubular shape and is made of polymer coated steel.
  • The fan has a sound insulation of mineral wool.
  • 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.
  • A three-phase asynchronous motor with a short-circuit rotor is installed in the fan casing.
  • The motor ingress protection rating is IP55.
  • The motor design ensures operation of the fan in the smoke extract systems on unidirectional and reverse modes.
  • The motors are rated for 400 V power mains voltage and 50 Hz frequency.
IMPELLER MOUNTING
  • Dynamically balanced impeller made of cast aluminium alloy.
  • 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.
