contamination in your air lines.
OIL COALESCING FILTER
Eliminate Oil Migration Problems
Vehicles making frequent stops, trucks equipped with high
air usage components (e.g.: lift axles, central tire inflation,
bulk unloading), or buses whose normal, day-to-day route
demands repetitive pneumatic operations (e.g.: kneeling,
door actuation) often cause a compressor to exceed its
recommended duty cycle.
Higher compressor duty cycles increase discharge
temperatures and allow the oil to remain as a fine aerosol
that can pass through the air dryer to condense downstream in air components. This condensed oil can cause
critical valves (e.g.: EGR actuators) and air powered
accessories to stick or even fail, resulting in reduced
component life and increased vehicle downtime.
The Bendix®PuraGuard QC™filter protects the air system
by removing excessive oil contamination in the supply air.
With an oil removal efficiency of 90 percent or greater, the
PuraGuard QC™ filter extends the life of air components
and reduces maintenance costs. The PuraGuard QC™filter
features an easy to service spin-on cartridge with an
integral heavy-duty drain valve.
Bendix Tested for Maximum
Performance
As pneumatic systems on today's vehicles become more
integrated, it is important for components to function
properly with other parts of the system. The PuraGuard
QC™ filter is compatible with all compressors and air
dryers when properly installed in the brake system.
The PuraGuard QC™filter has been extensively tested on
transit fleets and high-air-usage vehicles to ensure it meets
the durability and optimal on-road performance standards
you’ve come to expect from every Bendix product.

filter extends
the life of air components and reduces
maintenance costs.
Clean Operation
The filter within the Bendix®PuraGuard QC™unit
easily captures oil aerosols and particulate, as small as
one micron, in the air stream. The oil then collects in
the sump portion of the unit for periodic drainage
and proper disposal. The PuraGuard QC™filter also
features a patented built-in bypass valve that
allows supply air to continue through to the brake
system in the unlikely event the filter should become
clogged.
