Operating Your Air Compressor; Moisture In Compressed Air - RIDGID GP90150A Operator's Manual

Operating Your Air Compressor

Before starting the compressor,
thoroughly read all component
instruction manuals, especially
the engine manual.
All lubricated compressor pumps dis-
charge some condensed water and oil
with the compressed air. Install appropri-
ate water/oil removal equipment and con-
trols as necessary for the intended appli-
cation.
Failure to install appropriate
water/oil removal equipment
may result in damage to
machinery or workpiece.

Moisture in Compressed Air

Moisture in compressed air will form into
droplets as it comes from an air compres-
sor pump. When humidity is high or when
a compressor is in continuous use for an
extended period of time, this moisture will
collect in the tank. When using a paint
spray or sandblast gun, this water will be
carried from the tank through the hose,
and out of the gun as droplets mixed with
the spray material.
Drain liquid from tank daily.
Do not attach air tools to open
end of the hose until start-up is
completed and unit checks OK.
IMPORTANT: This condensation will
cause water spots in a paint job, especial-
ly when spraying other than water based
paints. If sandblasting, it will cause the
sand to cake and clog the gun, rendering
it ineffective.
A filter in the air line, located as near to the
gun as possible, will help eliminate this
moisture.
