Mount the Model RL00S Bootstrap Compressor on a
horizontal surface. Other mounting orientations are not
recommended. The booster vibrates while operating,
so use the four 7/32” mounting holes, shown in the
diagram to the right, to bolt it to a solid surface.
1
Connect your shop air line to the 1/4” 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 1/4” 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 280 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 140 psig, it is possible to set the regulator so the
booster exceeds the maximum discharge pressure of
280 psig. Do not operate the booster under these
conditions. It is designed to operate continuously at a
maximum discharge pressure of 280 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.
