APPENDIX B – DRYER FLOW CAPACITY
1. DRYER FLOW CAPACITY
The specific size/model of your dryer was selected to meet performance requirements
based on an analysis of air supply and demand capacities. The model selection chart
provided following should confirm that this dryer remains suitable for its intended use.

To correct for an inlet temperature other than 100°F multiply dryer capacity by the
temperature correction factor listed above.
Example
: To size for an inlet flow of 950 scfm @ 105°F and 110 psig.
Select models that produce at least 950 scfm at 110 psig. This case would be the
SD-1050 which can dry 1215 scfm.
Multiply pressure-corrected flow by the temperature correction factor to obtain
the flow of the dryer corrected for pressure and temperature:
1215 X (0.83) = 1008 scfm
Confirm model selection.
Model SD-1050 can flow 1008 scfm at the inlet
conditions specified. The requirement of 950 scfm is less, so model SD-1050 is
correct.
