Make sure you’re getting the real thing, look for the “Genuine Bendix”
Your brakes are a system, not a set of individual parts, and not the place to cut corners. A
poorly manufactured knock-off air dryer can put your entire system out of spec and have
unintended consequences on braking performance and stopping ability.
Why risk this on your vehicle?
Trying to save a few bucks on a non-genuine Bendix replacement air dryer
could result in a stranded vehicle, excessive wear on the compressor or
premature failure of downstream components/valves.
Stay with the company that pioneered commercial vehicle air dryers and has
been leading the way for over 4 decades. Genuine Bendix. Out performs.
Out lasts. Outstanding.
Why cut corners? Non-genuine products will cost more over the life of your vehicle. Protect
your vehicle by using only genuine Bendix

The picture shown is a dramatization
and is not an actual air dryer failure.
Comprehensive testing by Bendix Commercial Vehicle Systems has shown knock-off air
dryers, as compared to the industry leading Bendix® AD-9® air dryer, not only fall short of
Bendix specifi cations, but can lead to unintended consequences on braking performance
and stopping ability and damage to other components in the air brake system.

The facts speak for themselves... take a closer look
The knock-offs used in these tests are actual products bought right off the shelf, and it’s just a sample of what we fi nd every
day. It is these differences that can, and frequently do, affect the performance, durability and long-term reliability of your
braking system.

The Issue: Inferior O-Ring Material
The Impact: Air loss and excessive leakage, causing
unnecessary wear on other components
O-rings become deformed over time. Poor temperature range
performance due to o-ring breakdown results in excessive
leakage, causing unnecessary wear on other components.

Knock-off Cartridge Right Out Of The Box
The Issue: Broken Mounting Bracket
The Impact: Air dryer may separate from vehicle
frame
A broken bracket can lead to air dryer damage.
Knock-off Purge Valve High Temperature Durability
Missing oil
separator
Desiccant beads
turn to powder
The Issue: Lack of Quality Control
The Issue: Powdered and Oil Soaked Desiccant
The Impact: Contamination leading to downstream
component malfunction or failure
Inferior desiccant delivered 35% less drying capacity and was easily
fouled by oil, reducing dryer life by 50%. In addition, the desiccant
beads turned to powder, traveling downstream.
The Impact: Poor, or non-functional product
performance
Missing parts and poor workmanship were observed
with the component in its original box. For instance,
the oil separator missing means desiccant can easily
escape the cartridge and contaminate your entire
vehilcle air system.
The Issue: Purge Valve Came Apart
The Impact: Unable to build air – vehicle
down
Purge valve assembly bolt became loose during testing,
causing a massive air leak. The leak was more than the
compressor output. The knock-off failed after only
30% of the test was completed.
