VII. COMPRESSED AIR TREATMENT
The GO-A13-HA Hopper Car Gate Opener is designed to operate with a clean, dry air
supply at the required pressure (85 to 90-PSI) and air volume (114 CFM). Dirty and wet
air will result in sluggish operation, more frequent repair and replacement of parts due
to sticking, jamming and rusting of wearing parts. Moisture will also wash out the
required oils, resulting in excessive wear. A decreased air pressure at the Gate Opener
caused by a Regulator Gauge set too low or by restricted (too small) or plugged lines,
valves or couplings will cause a reduction in efficiency at the Gate Opener. Clean, dry
air at the required pressure (85 to 90-PSI) will enable the unloading site worker to start
immediately at an efficient level, with no time lost to purge the lines, drain the Filter,
set the Regulator Gauge or fill the Lubricator, and will help to maintain productivity and
prolong Gate Opener life.
WORKMASTER supplies a heavy-duty, preassembled, high air flow, combination 1"
FRL Service Unit. This Service Unit consists of: a Filter w/ Metal Bowl and Sight Glass; a
Regulator w/ Gauge; and a Lubricator w/ Metal Bowl & Sight Glass (PN: 82-10406) to
treat the compressed air supplied to the Gate Opener. This FRL Service Unit should be
installed as close as practical (the Service Unit should be rigidly mounted in an
activity/weather protected area), to the hopper car unloading site.
The Service Unit is mounted so that the Filter is upstream of the Regulator and
Lubricator. The top of the inlet side of the Filter is clearly marked with an " " for
proper connection from the compressed air system through the Service Unit.
