PuraGuard

System Filter

DESCRIPTION

The PuraGuard

system filter is used to assist the

production of purified compressed air on high air use vehicles.

The PuraGuard

system filter consists of a filter element

mounted in a die cast aluminum housing. The sump

housing contains a drain valve for maintenance. For ease

of serviceability, all maintenance kits do not require removal

of the PuraGuard

system filter from its mounting on the

vehicle.

High air use vehicles (e.g. transit vehicles) may require the

air compressor to exceed its normal duty cycle. The resulting

high compressor discharge temperatures can allow oil

aerosols to pass through the air dryer, condensing

downstream in air system components.

The PuraGuard

system filter follows the air dryer in the system

and removes approximately 99% of oil aerosols. On vehicles

not using an air dryer, the PuraGuard

system filter follows

the supply (“wet tank”) reservoir (see Figures 3 & 4).

OPERATION

GENERAL (See Figure 2)

Compressed air passes through the supply port of the

PuraGuard

system 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 air travels back up from the

sump, through the PuraGuard

system filter delivery port

and into the air system.
