The filter, regulator, and lubricator
ICD @E>>E@ABC
should be installed in the order shown
in the illustration below. If a coalescing
filter is required, it should be installed
downstream from a standard filter.
Individual take-off lines to the FRL and
Compressed Air
air tool or equipment should be from Filter Regulator Lubricator
Shut-off
the top of the compressed air line. Make valve
sure that air flow markings are followed
for proper flow direction through the 2000 Series
lockout valve
FRL units. To trap and expel water, Drip leg
drain
sludge and other contaninants which Pneumatic tool
may collect on the bottom of the air
line, a drip leg drain should be used.
Drip leg drains should be installed at
low points in the piping system and at
the far end of the distribution system. # $% &
