This compressor application matrix offers directional information when sizing a Bendix compressor for the applicable vehicle vocation.
Testing should still be performed on the specic application to verify that the compressor remains within the 25% maximum allowable
duty cycle. This application matrix assumes that all compressor installations use an air induction system that is naturally aspirated.
The “Compressor Installation & Application Review” form explains the methods used to measure the vehicle’s duty cycle.
