Performance information is for the model AX standard configuration. Optional configurations include; upblast design with butterfly dampers and curb cap, detachable air straightening vane section, and shortened case. These options can effect performance. For estimated pressure drops on these accessories, consult your local Greenheck representative.

Greenheck certifies that the Model AX fan shown herein are licensed to bear the AMCA seal. The ratings shown are based on tests and procedures performed in accordance with AMCA publication 211 and comply with the requirements of the AMCA Certified Ratings Program.
Hubs and Blades
The AX blade shape and hub are designed to move high volumes of air with less power to save on long-term energy costs. The choice of five different hub diameters, along with variations in blade quantities, ensures that the most economical air performance can be achieved. In addition, during the design process, close attention was paid to the “hub to tip” ratios. This is a comparison of the hub diameter to the “tip to tip” dimension of the blades. Different choices of hub to tip ratios further optimize fan performance and provide a cost effective solution by not over sizing a hub to produce required volumes and pressures. The hubs are constructed from cast aluminum and use a taper lock bushing to secure the hub to the motor shaft.

Performance shown is for installation type B; free inlet, ducted outlet. Performance ratings do not include the effects of appurtenances in the airstream. The AMCA Certified Ratings Seal applies to air performance ratings only.
Sound power level ratings are shown in decibels, referred to 10-12 watts calculated per AMCA Standard 301. Values shown are for inlet LwA sound power levels for 100%, 50% and 0% of peak pressure in Installation Type B: free inlet, ducted outlet. dBA sound pressure values are weighted with 11.5 dB attenuation for each octave band at 5 feet.

Selection Example and Warranty
Performance:
Volume - 0.5 m³/s
Pressure - 170 Pa Static Pressure
Power Frequency - 50 Hz
Results:
Following the constant static pressure line a size 31 with 160 hub and 4 blades needs:
• 15 degree blade pitch setting
• 2900 rpm motor
From the chart
• The operating efficiency is between 55 and 57%
Using 2900 Motor rpm and Peak Absorbed Power Table
• 0.18 kW peak absorbed power
Sound power falls between 68 and 66 LwA for the color matched 1770 rpm. Using the Inlet Sound table and estimating 67 LwA with 2900 rpm, the calculated sound power and pressure are:
• Sound Power of 80 LwA
• Sound Pressure of 68.5 dBA
