Designing an efficient HVAC air distribution system requires careful consideration of duct selection, sizing, airflow, pressure drop, insulation and installation. Flexible duct is widely used in HVAC systems for connecting supply and return air terminals, diffusers, grilles and other air distribution components. However, the performance of a flexible air duct system depends significantly on how the duct is selected, sized, routed and installed.

​

The SamcoFlex HVAC Consultant Resource Center provides practical technical information and engineering guidance for consultants, HVAC designers, MEP engineers, contractors and other professionals involved in the design and specification of flexible duct systems.

​

From selecting the appropriate type of insulated flexible duct for a particular HVAC application to understanding flexible duct diameter, airflow velocity, duct length, friction loss and pressure drop, these resources are designed to help professionals make better-informed decisions during HVAC system design.
