Diffusers, Registers & Grilles: submittal requirements
HVAC packages are equipment-heavy, and every unit gets checked against the schedule: capacity, electrical, dimensions, and sound. Ductwork, insulation, and air distribution ride along with their own data.
What reviewers expect in a diffusers, registers & grilles package
- Equipment data keyed to schedule tags with capacities at the scheduled conditions
- Electrical characteristics (MCA, MOCP, voltage) matching the electrical drawings
- Fan curves with the operating point plotted
- Diffuser/register/grille schedule with sizes, throws, and NC ratings
- Duct construction standards and insulation data (R-value, jacket, thickness)
- Vibration isolation and seismic restraint details where specified
- Controls sequence compatibility — points list matching the BAS spec
Field tip
Highlight the scheduled operating point on every fan curve and capacity table. Reviewers reject packages where they have to find it themselves — marked curves get approved.
