FabricAir ducts are designed to have low internal velocities and if needed can also have low velocities in the occupied zone. A typical FabricAir system is designed to have an inlet velocity of between  6-8 m/s [1200-1600 FPM]. At these low velocities the noise generated by the air stream is kept to a minimum allowing for very low NC levels. There are applications that require low velocities in the occupied zone, such as office settings or refrigerated facilities with employees, to achieve full occupant comfort. FabricAir can achieve this by varying the size, spacing, and number of orifices, nozzles, etc. at the manufacturing facility so that the duct is ready to install on-site without the need for balancing.

Due to the low static pressure drop (often as low as 25 Pa [0.1" WG]) and more efficient air distribution methods, FabricAir dispersion systems can greatly reduce the lifetime operating cost of the entire HVAC system.
