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
