Backward inclined airfoil centrifugal fans for industrial and commercial application with AMCA certification for performance and sound with best available performance efficiency. These can be used as industrial blower, process fans, space pressurisation in most demanding conditions.

Greenheck offers GJ, jet fans for unidirectional and reversible direction airflow, for ductless car park, tunnel ventilation system. These fans provide highly linear air flow, without need of air ducts. AMCA Air & Sound certified, these fans are highly efficient, very low sound, high performance, thereby ideal for installation high demanding application, and also in occupied areas.

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: 300C for 2 hours (F300 Certificate 370-CPR-1745) and 400C for 2 hours (F400Certificate 370-CPR-1848) available on select models. Tested and certified in accordance withEN12101-3:2002
• IEC rated motors: 50 Hz or 60 Hz motors available, in single or two speed, VFD rated, and EFF2 orIE2 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

Greenheck (India) offers high performance and high fan efficiency (upto 84% FEG) vane axial fan.

Each RA Fans are AMCA air & sound certified, with sound level as low as 75 dBA. These are available upto 1600 mm diameter, with various mounting options available.

These fans can be used in all air, smoke and fire ventilation application, including parking, tunnel, stairway, lifts, hall, office, exhaust, fresh air etc.

Models SWD, USF and CSW fans are designed and built in one of two manufacturing locations, Schofield, WI and Shelby, NC. Multiple manufacturing locations enables us to build fans and get them to you, our customer faster.
