The following resources are available from Moore at no cost and are available
for downloading below.
Anyone responsible for selecting or
operating industrial axial flow fans needs some basic knowledge of fan design and
utilization in order to make optimum decisions. Moore has prepared a number of
short technical articles, one printed page or less, covering these basic
subjects. We hope you will find these "Tech NOTES" helpful.
For more in-depth information, select see “Engineering Papers” section
below.
Engineering Papers and
Owner's manuals for Moore fans below require Adobe Acrobat Reader®. (Acrobat
Reader 5.0 or newer is recommended) If you do not have Acrobat
Reader® on your computer, a free download is available at the link

TECH NOTES:
-
HOW TO RECOGNIZE A
HIGH-EFFICIENCY FAN Describes the complex blade shape
necessary to provide uniform flow, the most important requirement of a fan
wheel.
-
WHY MOORE FANS HAVE TWO HUBS Explains
the considerable difference between the aerodynamic and structural
requirements of a fan hub.
-
METHODS FOR MODULATING AIRFLOW Compares the three common methods for
reducing airflow as conditions permit, to reduce power use and lower noise
level.
-
HOW TO SELECT A LOW-NOISE FAN Noise
level calculation formulae indicate performance considerations for
reducing noise and other means of lowering noise are discussed.
- THE ADVANTAGES OF RESILIENT
"HELICOPTER" BLADES Discussion of the reduction of stress and the avoidance of
critical speeds using variable-speed motors.
-
COOLER UPGRADING: A TIMELY TOPIC
ENGINEERING PAPERS:
- THEORY OF RATING The basic definitions and
formulas used in fan selection.
- FAN DESIGN Considerations in the design of
axial flow fans for high energy and efficiency.
- RESONANCE OF PIVOTED BLADES Calculation of
resonant frequencies for Moore fans with pivoted fan blades.
- NOISE LEVEL PREDICTION Gives formulas used by
Moore to predict noise levels at user-defined locations and for multiple
aerial cooler fans.
- MODULATING AIR FLOW Gives formulas that can be
used to estimate horsepower, PWL and SPL resulting from modulating air
flow.
