How much are you willing to risk?

Experience peace of mind with PuraGuard

In the past, you didn’t need to think too much about your air dryer. You could get by with “good enough.” You could simply “wait and see” before committing to advancements like oil coalescing technology.

Manufacturers responded to EPA ’07 and ’10 with major technical advances to their vehicle systems. These advances – including Advanced Exhaust Gas Recirculation (EGR), Selective Catalytic Reduction (SCR), and the Diesel Particulate Filter (DPF) – have added a total of $10,000 to

But those days are now gone.

Whether you’re an OE, ﬂ eet, or owner-operator, you operate in a world of increasingly strict emission standards and higher costs of running your business. EPA regulations in 2007 and 2010 dramatically reduced the allowable diesel engine emissions of nitrogen oxides

$15,000 to the cost of each commercial vehicle. As costs rise, so does the pressure to protect your investment.

When air contaminated with oil is sent into these systems, you risk considerably shortening its life and possibly spending a great deal to repair it.

Proven Bendix® PuraGuard® Oil Coalescing Technology

First Phase:

Skin Cooling - Lowers the temperature, converting aerosols to liquid

Second Phase:

PuraGuard® Treatment - Coalesces and collects oil particles, protecting the desiccant from contamination

Third Phase:

Recyclable desiccant removes moisture by adsorption

clean dry air

Laboratory tests show that Bendix air dryers with PuraGuard® oil coalescing technology signiﬁ cantly outperform the WABCO® SS 1200 air dryer cartridge with coalescing ﬁ lter.

Preventive Maintenance – as easy as 1-2-3

Adhering to a strict preventive maintenance schedule is crucial to keeping a vehicle’s air system clean and ensuring superior performance. 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. Line-haul operations using a single trailer should swap the filter out every 3 years or 300,000 miles. (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.)

More frequent intervals may be required depending on a vehicle’s age, its compressor

condition, the operating environment, the vehicle’s vocation, and its usage. In conjunction

with the 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.

For better air dryer performance, non-oil coalescing cartridges can be upgraded to the Bendix® PuraGuard® oil coalescing cartridge. However, if the Bendix® PuraGuard® oil coalescing cartridge is an OE Standard it must be replaced with a like unit.
