Series Vents JAF

Series Vents JAF - Axial fans - Jet fans
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. Functionality. Power. Efficiency.
Application

JAF jet axial fans are designed for general purpose ventilation of underground and semi-opened 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.


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


Design

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.

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.


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.


Mounting

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
