stages prior to entering the dehydrators. Cooling is
accomplished by air being drawn through the cooler
subassembly by the fan mounted on the compressor
crankshaft. Hinged doors are provided on the control
panel. These doors control the amount of air drawn
through the cooler assembly and blown over the
compressor assembly. Each air cooler stage is
equipped with a pressure relief safety valve.
1-8. AIR COMPRESSOR GROUP (16, Figure 1-1).
The air compressor assembly is a four cylinder, air-
cooled, radial compressor. Compression of air from
initial intake to final discharge is accomplished in four
distinct stages. Discharge pressure is indicated on the
instrument panel pressure gauges. Lubrication of the
moving parts is provided by an oil pump located in the
non-drive end cover. A air circulating fan mounted on
the non-drive end of the crankshaft is used to circulate
air over the compressor assembly.
1-9. CLUTCH AND HOUSING GROUP (17, Figure 1-
1). The clutch group is a single plate, manually operated,
dry type clutch. A clutch rod and hand lever are used to
operate the clutch. The clutch rod extends to the rear
and through the control panel. This allows the operator
to engage and disengage the clutch. The clutch housing
aligns the engine with the air. compressor. A cover on
the housing allows access to the clutch.
1-10. ENGINE AND ACCESSORIES GROUP (26,
Figure 1-1 ). The diesel engine assembly is a four stroke
cycle, direct injection, air cooled, diesel engine. The
engine is used to drive the air compressor through the
manually operated clutch.
at a rated speed of 2,150 rpm (2,150 r/min). Engine
accessories include a 12V alternator, intake air filter, fuel
filter, lubricating oil filter, and electrical starting motor.
Operating controls for the engine are located on the
control panel assembly. The AMMETER, & ENGINE OIL
PRESSURE gauge are located on the instrument panel.
1-11. DRAIN VALVE ASSY. AND UNLOADER
CONTROL BOX GROUP (22, Figure 1-1). When air
pressure in the system reaches a pre-determined value,
a pressure switch in the unloader control box will open.
This ceases loading of the compressor. The drain valve
assembly will then open, allowing moisture and air to be
exhausted to the condensate receiver assembly.
1-12. FRAME AND SKID GROUP (24, Figure 1-1). The
frame on which all the major components are mounted is
welded, single unit frame work. The air compressor,
clutch assembly and engine are shock mounted to the
skid by steel cross members. A fuel tank with capacity
for not less than eight hours of operation is mounted
inside the frame work. There are lifting and tie-down
eyes at each corner of the frame. These allow the
complete unit to be hoisted without damage. The eyes
may also be used for tying down the air compressor unit.
Provisions have been incorporated in the frame/skid to
allow movement of the air compressor unit by using the
proper size fork lift truck.
