System Balancing
(Model MLS-01-5500-10 ONLY)
Before fully releasing your new RoboVent into production, RoboVent recommends a
system balance. Balancing is recommended to ensure the designed velocity and airflow is
being pulled from each drop on the system.
The following process is a high-level view of how to balance an industrial ventilation
experts. Balancing should only be completed by trained ventilation experts. If you
interested in having your system(s) balanced or rebalanced, contact RoboVent at
1-888-ROBOVENT.
1. Prior to starting the Balancing Procedure ensure that all autogates/manual blast gates
are fully open for the entire system.
2. Following the balancing print (engineering drawing showing airflow requirements at
each air pick-up point on your system), locate the drop with the highest pressure draws.
3. Balancing should start at the highest static point.
4. Record the elevation of the plant, the temperature within the ductwork, and the
static pressure within the ductwork. If these values stray from the standard (Standard:
Elevation > 1000 FASL; Temperature > 90 F; Static Pressure 20” w.g.) you must do a
density factor correction.
5. Starting with the highest static point adjust the VFD until the required CFM is
achieved (Blast Gate must be fully open).
6. Move to drop number 2 on the balancing print. Adjust the blast gate until the
desired CFM is reached.
7. Repeat for the remaining drops in descending order.
8. Record all values (velocity and static pressure at each drop).
9. Once complete go back to the first drop and re-check the system. If the
measurement is within 15% of the original value obtained at that location the
balancing is complete. If the value strays more then 15% from the original value, then
the system needs to be checked for changes, and/or re-balance the system.
