Air Flow

Air Flow
See the chart to determine air consumption. Add the air consumption values shown for the atom-
izing air and fan air to get the total air consumption. For example, air cap 24C182 with 35 psi inlet
pressure uses 3.9 scfm atomizing air and 5.4 scfm fan air for a total of 9.3 scfm air consumption.
