Primary air duct
WebDuct systems are often divided into three pressure classifications: Low Pressure Systems - where fan static pressures are less than 3 in WC (750 Pa) and duct velocities in general less than 1500 fpm (7.5 m/s); Medium Pressure Systems - where fan static pressures are in the range 3 to 6 in WC (750 - 1500 Pa) and duct velocities in general less than 2500 fpm (12.5 … Webvariable air volume (VAV) system, each zone is conditioned by a box with a small fan that draws-in plenum return air and mixes it with supply air from a primary system. The primary system is similar to variable air volume (VAV), with the primary air supplied at a fixed temperature. Series fan-powered systems provide each zone with
