SAFETY
DEFINITIONS
a
DANGER WILL cause DEATH, SEVERE INJURY or
substantial property damage.
aWARNING CAN cause DEATH, SEVERE INJURY or
substantial property damage.
aCAUTION WILL or CAN cause MINOR INJURY or property
damage.
GENERAL SAFETY PRECAUTIONS
a
DANGER INTAKE AIR. Can contain carbon monoxide or
other contaminants. Will cause serious injury or
death. Ingersoll-Rand air compressors are not
designed, intended or approved for breathing air.
Compressed air should not be used for breathing
air applications unless treated in accordance with
all applicable codes and regulations.
aWARNING HAZARDOUS VOLTAGE. Can cause serious injury
or death. Disconnect power and bleed pressure
from the tank before servicing. Lockout/Tagout
machine. Compressor must be connected to
properly grounded circuit. See grounding
instructions in manual. Do not operate
compressor in wet conditions. Store indoors.
MOVING PARTS. Can cause serious injury. Do not
operate with guards removed. Machine may start
automatically. Disconnect power before servicing.
Lockout/Tagout machine.
HOT SURFACES. Can cause serious injury. Do not
touch. Allow to cool before servicing. Do not
touch hot compressor or tubing.
HIGH PRESSURE AIR. Bypassing, modifying or
removing safety/relief valves can cause serious
injury or death. Do not bypass, modify or remove
safety/relief valves. Do not direct air stream at
body. Rusted tanks can cause explosion and
severe injury or death. Drain tank daily or after
each use. Drain valve located at bottom of tank.
aCAUTION RISK OF BURSTING. Use only suitable air
handling parts acceptable for pressure of not less
than the maximum allowable working pressure of
the machine.
GENERAL INFORMATION
INTRODUCTION
This manual provides safe and reliable instructions for the installation,
operation and maintenance of your Ingersoll-Rand air compressor.
Carefully read this manual before attempting to operate or perform any
maintenance. If you are uncertain about any of the instructions or
procedures provided in this manual, contact Ingersoll-Rand. We
recommend you retain this manual, and all publications provided with
your air compressor, in a location which is accessible to all personnel
who operate and service your compressed air equipment.
APPLICATION
Ingersoll-Rand’s standard two-stage lubricated air compressors are
single-acting, air-cooled machines. Typical compressors are furnished
as compact, self-contained, air receiver tank mounted units that are
automatically regulated and driven by an electric motor. An air-cooled
aftercooler, low oil level shutdown switch and automatic drain valve
are among the optional accessories that can be furnished. Bare
compressor pumps and baseplate-mounted units are also available.
These compressors may be used for a variety of compressed air
application up to 250 PSIG (17.5 kg/cm²). Application of these
compressors as either a primary or supplementary source of air is
virtually unlimited in industrial plants, service stations and auto repair
shops. Supplementary service includes such uses as furnishing air at
pressure not carried in regular shop lines, air at isolated locations, and
standby service for air when larger compressors are shut down.
TWO-STAGE OPERATION
The basic principle of operation is as follows: On the suction stroke of
the first-stage piston(s), air at atmospheric pressure enters the
cylinders through the inlet filter(s) and then the inlet valves located in
the head. On the compression stroke of the first-stage piston(s), the air
is compressed to an intermediate pressure and discharged through the
discharge valves(s) into common manifold(s). From the manifold(s) the
air passes through the intercooler tubes, where the heat of first-stage
compression is removed. On the suction stroke of the second-stage
piston this cooled air enters the second-stage cylinder through the inlet
valve. The compression stroke of the second-stage piston compresses
the air to the final discharge pressure and forces it out through the
discharge valve into the receiver tank or system. If cooling of the
discharge air is required, an air-cooled aftercooler should be installed
between the compressor discharge and the receiver tank or system.
