AIR DRYER APPLICATION GUIDELINE

1 The following APPLICATION GUIDELINE is a point system that is calculated based on Vehicle Confi guration and Vocation Options. Fill in points accordingly on each line and refer to Page 2 for DRYER selections. If a particular entry is not valid for an APPLICATION , then enter ZERO on that line. Refer to Page 3 for example CONFIGURATION POINTS 1. Vehicle is equipped with bulk offl oading or Central tire infl ation. See Note 1 2. For every axle (tractor and trailer including lifts): Add point 3. For each non-steerable lift axle (additional points): Add point 4. For each steerable lift axle (additional points): Add point 5.

For example, Line Haul applications are limited to single tandem axle dryers must be matched models ( two AD-IS or two AD-9 , etc.). Both dryers must be extended purge is no required compressor charge time or purge time. Operation is controlled through the EverFlow module. APPLICATION Air Dryers AD-IP AD-9 EP Tandem
