DESCRIPTION

The PuraGuard QC oil coalescing filter provides purified
compressed air on any air braked vehicle. It consists of a
spin-on housing, or cartridge, mounted to an aluminum body.
The spin-on cartridge contains a drain valve for maintenance.
For ease of serviceability, the spin-on cartridge can be
removed without disconnecting the supply and delivery lines
of the PuraGuard QC ™ oil coalescing filter from its mounting
on the vehicle.

OIL COALESCING FILTER
Vehicles operate best with clean, dry compressed air. The
PuraGuard QC ™ oil coalescing filter removes approximately
90% of oil aerosols and particulates down to 1 micron in
size, but it must be used in a system with and follow an air
dryer.
OPERATION
GENERAL
(See Figure 2)
Compressed air passes through the supply port of the
™
PuraGuard QC oil coalescing filter and travels downward
through the center of the filter element. As the air passes
through the filter material, oil in liquid and aerosol form are
removed and collected in the sump. The PuraGuard QC
filter also collects solid particles 1 micron and larger. The
cleaned air travels back up from the sump, through the
delivery port and into the air system.
