Calculate duct size easily and instantly with the Duct Wizard! This handheld rotating calculator makes sizing supply and return duct systems a cinch - in all HVAC/R applications.

On one side you'll get the proprietary rotating duct calculator, complete with the tools you need to:

• Establish Air Quantity (CFM) and Friction Loss
• Set Air Quantity (CFM) opposite of Friction Loss
• Read Velocity (FOM) opposite of Air Quantity (CFM)
• Read Duct Diameter, Equivalent Regular Duct Dimension, and more!

On the opposite side, you'll find an at-a-glance guide to the reference charts and tables you rely on every day, including the following and more:

• Commonly Used Fittings and Connections
• Round Trunk Duct Fittings
• Angles and Elbows for Trunk Ducts, Individual and Branch Ducts
• Boot Fittings
• Basic Air Conditioning Formulas (cooling, heating and/or humidifying)
• Formula Legend
• Derivations of Air Constants
• Recommended and Maximum Duct Velocities
• Recommended Gauges for Sheet Metal Ducts
• Gauges and Data for Average Local Exhaust Systems

Example:

Given: 300 CFM @ .08 Inches of Water per 100 ft.
Find: Size of Round Duct, Velocity, Equivalent Duct Dimensions.

Solution:

• Read Velocity @ 650 FPM
• Read Duct Diameter @ 9.2"
• Read Duct Dimensions 6" X 12" or 5" X 15"
