Near zone
The near zone is a term that is applicable to surface flow models (SFM). This zone is defined by the length from the duct at which the air velocity is too high for comfortable conditions. When dealing with office space design this velocity is typically set at 0.25 m/s [50 FPM]. Other applications, such as refrigeration, would use 0.15 m/s [30 FPM] due to the colder supply air temperatures, which can cause discomfort at lower terminal velocities.

FabricAir dispersion systems are fully customizable and can be tailored to your specific needs. 

FabricAir ducts are designed to have low internal velocities and if needed can also have low velocities in the occupied zone.
