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.

Size ductwork using constant pressure drop, velocity, or static regain calculations.

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.
