Bendix® PuraGuard QC™ Oil Coalescing Filter

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.

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.
