With the blower at full load air speed,
take a reading from the Digital
Manameter. Check the reading against
the IOM blower tables or in the tables
shown below to determine the maximum
external static pressure.
Verify that all grilles and registers are
open and free.
Use a Magnetic Static Pressure Tip tool
(far right) to check the static pressure.
Add both together to get Total Static
Example: .39 Static Pressure
