Description

Jet Fans (Model: GJ)pdf-image

AMCA Air & Sound Certified Jet Fans, High Efficiency upto 84%, Low Sound
Make: Greenheck (USA) India
Model: GJ

greenheck GJ jet fans
Model: GJ Ventilation in ductless application

Greenheck (USA) India high performance, high efficiency yet very silent jet fans. These Jet fans are ideal for installation in occupied enclosed parking area, tunnels and other areas where linear ventilation is required.  vane axial fans.

Model Greenjet or GJ is available in both unidirectional series (GJ-AU) and the reversible series (GJ-AR). Both come standard with inlet and outlet silencers, inlet guards, mounting feet and aluminum die cast propellers and blades.

GJ-AU series features a true airfoil propeller which is designed to move high volumes of air at a high efficiency in a smaller diameter fan. The GJ-AR features a 100 percent reversible, highly efficient, airfoil blade design.

Key Features:

  • Aluminum airfoil propeller: Move high volumes of air with maximum thrust and maximum efficiency.
  • Galvanized casing: Continuously welded to prevent air leakage.
  • Motor plate: Securely welded to fan inner tube to improve rigidity and prevent vibration.
  • Silencers: Available in two options – short (one diameter length) and long (two diameter length).
  • Direction vanes: Available on select models to direct airflow.
  • Smoke extraction: 300°C for 2 hours (F300 Certificate 370-CPR-1745) and 400°C for 2 hours (F400
    Certificate 370-CPR-1848) available on select models. Tested and certified in accordance with
    EN12101-3:2002
  • IEC rated motors: 50 Hz or 60 Hz motors available, in single or two speed, VFD rated, and EFF2 or
    IE2 efficiency
  • AMCA air and sound certified

Key Considerations:

  • Standards: Apply relevant codes such as NFPA, IBC, ASHRAE, and European Standards
  • Required air changes: Optimize air flow for normal and fire modes
  • Sound: Reduce sound levels to acceptable limits for tenants
  • Control strategy and sequencing: Define sensor to fan correlation and system response
  • Accessibility and aesthetics: Advise on placement of ramps, wall openings, and pedestrian exits
  • GreenPark components: Reduce cost and optimize safety with selection and placement

Typical Ventilation Applications area include:

  • Enclosed / Basement air and smoke ventilation
  • Enclosed / Basement car park air and smoke ventilation
  • Tunnel ventilation
  • Linear air ventilation, in industries etc
  • Ductless ventilation system
