CFM and Sizing Calculations

Previous Feature: Fittings - Next Feature: Pressure Loss Calculations

Design Master HVAC integrates the duct sizing calculations directly into the drafting of the ductwork.  You set the CFM values at the diffusers, define a sizing method, and the software takes care of the rest.  Never spin a Ductulator again.

Choose Your Sizing Method

Choose the duct sizing method that is right for your project.  You can even change how you size ducts midway through a system.  Use static regain from your main air handler to the VAV boxes, and then slow it down using the constant pressure drop method.
