Donaldson Engine Air Filter Catalogue

FLB Air Cleaner

When specifying an Air Cleaner… Determine the Airflow Requirements of your engine, then find the corresponding m ³ /min. airflow in the charts below. The restriction numbers - shown in mbar at the left side of the chart - indicate the approximate initial restriction of each model air cleaner at that m ³ /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.
