High Performance Axial Fans

Model AX

Performance Supplement

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.

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.

AX Short CasingAX Vane SectionAX Upblast

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.

High Performance Axial Fans

The performance pages contains information in metric and english units. These are color coded with motor

power frequency and motor speed for easy and quick reference in finding air performance, power requirements,

and sound information. See back cover for selection example.

Total Efficiency curves - Curves show total efficiency levels at different performance points. Those curves

do not reflect static efficiency levels.

Peak Absorbed Power table - Table displays the maximum power required by pitch angle and motor rpm.

Values provided are in brake horse power and kilowatts.

Sound Power and Sound Pressure table - Table displays the corrections required by motor rpm.

Outlet Velocity and Tip Speed formulas - For deriving outlet velocity, use either cfm or m³/s in the

appropriate Outlet Velocity equation. Tip speed equation is only dependent on motor rpm.

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.

AX 31-160 4 Blades

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
