Adhering to a preventative maintenance schedule is crucial to 
keeping a vehicle’s air system clean and ensuring superior 
performance of all components that utilize system air – such as 
brakes, emissions equipment and automated manual transmissions. 
Depending on vocation, Bendix recommends a 1, 2, or 3 year air 
dryer cartridge replacement on vehicles equipped with a Bendix 
compressor.

for severe service applications, such as residential refuse 
trucks or school buses, the air dryer cartridge should be 
replaced every year or 100,000 miles;

for pick-up and delivery operations, or for double- and 
triple-trailer line haul trucks, every two years or 200,000 miles 
is the recommendation; and

line-haul operations using a single trailer should swap the 
filter out every 3 years or 300,000 miles.

More frequent intervals may be required depending on a vehicle’s 
age, its compressor condition, use of a non-Bendix compressor, the 
operating environment, the vehicle’s vocation, and its usage. In 
conjunction with these guidelines, fleets can determine the 
functionality of their filters by checking for moisture in the air brake 
system monthly. If moisture is present, the air dryer cartridge may 
require replacement. Reference the Bendix Service Data Sheet of 
the specific air dryer for additional information. (Recommended 
intervals for trucks equipped with non-Bendix compressors are 
6 months (50,000 miles), 1 year (100,000 miles), and 2 years 
(200,000 miles), respectively). IMPORTANT! When servicing, note 
that standard AD-RP air dryers or air dryer cartridges may be 
serviced with PuraGuard oil coalescing air dryers or cartridges, 
however, PuraGuard oil coalescing air dryers or cartridges MUST
only be serviced with like replacements.
