Chilled Water Fan Coil Units Fitting Details With Duct Sizes

This AutoCAD DWG drawing provides comprehensive chilled water fan coil unit fitting details prepared for HVAC installation and coordination drawings. The file includes typical fittings for fan coil unit connections, such as supply and return duct transitions, duct size variations, wall offsets, and elbow arrangements. Rectangular duct sizes ranging from approximately 4 inches by 8 inches up to 8 inches by 10 inches are clearly indicated along with proper turning vanes and connection offsets. Details also show fresh air intake, return air configuration, and plenum box arrangements with accurate dimensions and orientation references.

The drawing further illustrates chilled water piping and FCU interface details, including rubber isolators, canvas connections, vibration isolation arrangements, and mounting clearances. Installation details for floor and ceiling interfaces highlight insulation placement, grille fixing, and duct penetration through walls and slabs. Each fitting detail is clearly labeled to support construction accuracy, maintenance access, and airflow efficiency. This AutoCAD DWG file is suitable for HVAC engineers, MEP consultants, architects?, and contractors who require reliable chilled water fan coil unit fitting drawings with clear measurements and standardized details for residential, commercial, and institutional HVAC projects.
