TABLE A

COMPRESSOR & AIR DRYER APPLICATION SELECTION MATRIX

This matrix is intended for use as a general guide; if you have experience with applications contrary to those

listed below, Use your experience as a guide. If your vehicle is equipped with high air usage accessories not

referred to below, use the compressor duty cycle guide at the bottom of the matrix (i.e. air wipers, tag axles

regularly lifted for cornering, large accessory air cylinders, air start, etc.)

* In Off-Highway applications where electronic engines are used, a TF-550 compressor may be sufficient.

** Required to run two (2) governors, one at 85 psi and one at 120 psi to reduce strain on drive train when

compressor inlet is turbocharged.

*** Vehicles without an air dryer must be drained daily.

Note: It is recommended that the compressor duty cycle not exceed 25% to ensure the normal life of the

compressor. In circumstances where duty cycle is anticipated to exceed 25%, a larger compressor model (i.e. a

TF-750 instead of a TF-550) is recommended.
