N/R – No Points Required – Application is not dependent on point totals.
When selecting a Bendix® AD-SP® air dryer, note this dryer is intended for servicing low-demand air systems. For example, Line Haul applications
are limited to single tandem axle trailers.
3
Tandem dryers must be matched models (i.e. two Bendix® AD-IS® or two Bendix® AD-9® air dryers, etc.). Both dryers must be extended purge
versions.
4
There is no required compressor charge time or purge time. The operation is controlled through the Bendix® EverFlow® air dryer module.
5
The Bendix® AD-9si™ air dryer is not available in tandem or EverFlow configurations.

Drain reservoirs and change the desiccant cartridge more frequently if more than just traces of moisture are found in any of the reservoirs.
The Bendix® PuraGuard® oil coalescing air dryer cartridge
has an identical appearance to the standard air dryer
cartridge, but contains oil coalescing media at the inlet of
the desiccant bed. This coalescing media provides a much
higher level of oil removal compared to the standard air
dryer cartridge. The PuraGuard oil coalescing cartridge
has all of the same functions as the standard cartridge and
is used in applications where lower oil concentration levels
are required.
For Bendix PuraGuard oil coalescing air dryer only:
Preventive Maintenance is as easy as 1-2-3
IMPORTANT! When servicing, note that standard air dryer
cartridges may be serviced with PuraGuard oil coalescing
cartridges, however, PuraGuard oil coalescing air dryers or
cartridges MUST only be serviced with like replacements.
For severe service application —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. Line-haul operations using a single trailer
should swap the filter out every three (3) years or 300,000
miles. The recommended intervals for trucks equipped with
non-Bendix® compressors are 6 months (50,000 miles),
one year (100,000 miles) and two years (200,000 miles),
respectively.
Adhering to a preventive 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.
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 nonBendix compressors are 6 months (50,000 miles), one
year (100,000 miles) and two years (200,000 miles),
respectively.)
