SRB Performance Curves
When specifying an Air Cleaner…
Determine the Airflow Requirements of your engine, then find the corresponding m³/min. airflow in the charts be-
low. The restriction numbers - shown in kPa at the left side of the chart - indicate the approximate initial restriction
of each model air cleaner at that m³/min. When calculating total initial restriction of the entire air intake system,
include the restriction caused by ducting, elbows, pre-cleaners, etc. The estimated lab life hours are indicated at
the right side of the chart.
