Mount the Model R00S Bootstrap Compressor on a
horizontal surface. Other mounting orientations are not
recommended. The booster vibrates while operating,
so use the four 7/16” mounting holes, shown in the
diagram to the right, to bolt it to a solid surface.
1
Connect your shop air line to the 1/2” FNPT air inlet
filter on the front of the booster. A shutoff valve can
be installed upstream of the filter for convenient
removal of the system for maintenance. The booster
has a built-in discharge pressure regulator. Do not
install a supply pressure regulator. Lowering the
supply pressure reduces the efficiency of the system.
The unit is permanently lubricated. Use of an inlet
lubricator will void the warranty. The
maximum inlet pressure is 150 psig.
2
Attach discharge line to the 1/2” FNPT brass street
elbow on the front of the booster. If the application
requires a lubricator, make sure the lubricator
is installed downstream of the booster. A filter
should be installed to protect downstream components
from seal/booster wear particles.
3
The discharge pressure regulator is set by the black,
snap-lock knob mounted on the top of the unit. Pull up
on the knob to unlock it. Adjust the knob by turning it
clockwise for a higher discharge pressure (up to a
maximum of 230 psig), or counterclockwise for a
lower discharge pressure. Inlet pressure is read on the
gauge closest to the inlet connection. The second
gauge indicates discharge pressure. Supply shop air to
the booster and it will start to operate. Set the regulator
to attain the desired discharge pressure, and push
down on the regulator knob until it “clicks” to lock the
regulator on that setting. The regulator is self-
relieving. When the discharge pressure setting on the
regulator is reduced, the higher pressure stored in the
system will vent through the regulator until pressure
equilibrium is reached. If the inlet pressure is higher
than 115 psig, it is possible to set the regulator so the
booster exceeds the maximum discharge pressure of
230 psig. Do not operate the booster under these
conditions. It is designed to operate continuously at a
maximum discharge pressure of 230 psig.
4
The Bootstrap Compressor will operate as long as
there is demand for high pressure air. When there is no
demand, the booster will “stall” at the pressure set by
the discharge regulator. The stalled condition
consumes no energy and does not damage the booster.
The booster will start up automatically when the
pressure falls slightly as a result of demand for high
pressure air.

Please refer to the operating description on the right, and the
schematic above to gain an understanding of the design principles
and mechanical function of the R00S Model Bootstrap Compressor.
The moving parts of the Bootstrap Compressor are permanently
lubricated with a multipurpose grease (except for the check valves).
Operation with a lubricator upstream voids the warranty. If a
lubricator is required, it should be installed on the downstream
(discharge) side. A well-maintained 5 micron inlet air filter is
required to maintain the warranty by ensuring that no dust particles
enter the unit and foul the seals, or cause premature wear of the
highly-polished seal surfaces. The wear parts in the booster consist
of check valves, springs and dynamic seals. These parts are
designed for 1800 miles of piston travel. The four-way valve, which
controls movement of the pistons, is a lapped, stainless steel valve
with no elastomeric seals subject to wear. Under normal conditions,
this valve will provide many years of operation. The discharge
regulator built into the center of the unit sees very little wear, and is
designed to provide many years of service under normal conditions.
The wear parts are typically replaced 2 to 3 times before a valve or
regulator kit is required.

The plant air stream always fills Compression Chambers A1 and A2
directly, through a set of check valves. These two chambers are
always pressurized to the maximum initial air pressure available
(the R00S Model Bootstrap Compressor is not designed for inlet air
pressures higher than 150 psig). A branch of the plant air stream
flows through a pilot-activated regulator, which reduces the pressure
to the level required to attain the desired Bootstrap Compressor
discharge pressure (the discharge pressure is set manually by
adjusting the regulator handle). This regulated air stream flows
through a four-way valve which directs it to Drive Chamber B2. At
the same time, the four-way valve opens Drive Chamber B1 to
exhaust. The pressure force exerted on the interconnected pistons by
the pressures in Drive Chamber B2 and Compression Chamber A1,
is sufficient to compress the air in Chamber A2 to a higher pressure
(the maximum discharge pressure attainable is two times the plant
air pressure). At the end of its travel, Piston 2 switches the four way
valve, which opens Drive Chamber B2 to exhaust, and pressurizes
Drive Chamber B1 with regulated drive air, thus reversing the
direction of the interconnected pistons, until Piston 1 switches the
valve back to its original position. The interconnected pistons
shuttle back and forth continuously, producing a high pressure air
stream, determined by the discharge pressure set on the built-in
regulator. The R00S Model is designed to operate at a maximum
discharge pressure of 230 psig. Higher discharge pressures, though
possible, can result in catastrophic failure of the booster.
Operating Description
General Concerns
Midwest Pressure Systems, Inc. warrants the R00S Model Bootstrap Compressor to be free of defects in material and workmanship for
a period of one year after purchase, except piston seals, rod seals, and check valves which are warranted for six months after purchase.
We will either repair or replace a failed unit returned by the customer. No other warranty is expressed or implied. Proof of the purchase
date is required. This warranty does not apply to equipment which has been abused, and is voided by use of a lubricator, or failure to
use a well-maintained inlet filter. Customer must obtain a return authorization number before shipping the unit to the factory.
