ENGINEERING PAPERS INDEX

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 provided:

TECH NOTES:

1. 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.
2. WHY MOORE FANS HAVE TWO HUBS Explains the considerable difference between the aerodynamic and structural requirements of a fan hub.
3. METHODS FOR MODULATING AIRFLOW Compares the three common methods for reducing airflow as conditions permit, to reduce power use and lower noise level.
4. 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.
5. THE ADVANTAGES OF RESILIENT "HELICOPTER" BLADES Discussion of the reduction of stress and the avoidance of critical speeds using variable-speed motors.
6. 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.
