AIR BALANCING SUMMARY
This project has been balanced per plans and specifications using the National
Environmental Balancing Bureau (NEBB) standards and procedures.
The fans have been checked for fan data, operating amperage, volta e, rotation, RPM,
P 9 9
I belt tension, alignment, and operating static pressure. All outlets have been proportioned
to ± 10% of the percentage of total airflow of the system unless otherwise noted.
RTU -1 There are no volume dampers for the four plenum diffusers to move air to outlet
#5 which supplies the vestibule.
RTUs -2,3,4 Are typical Units supplying the main Warehouse and meeting design
requirements.
RTU -5 Is running at Full Load Amps and producing 89% of design. Not all branches have
volume dampers, however it does match the drawings. The system was proportioned as
well as possible.
RTU -6,7,8 Are all meeting design specifications.
EF -1 -5 Are all Direct Drive fans with rheostat speed control. Fan speeds are set as close
as possible to design.
