IMPORTANT: Discharge piping should be at least as
large as the discharge connection at the compressor.
All piping and fillings must be suitably rated for the
discharge pressure and temperature.
A careful review of piping size from the compressor
connection point is essential. Length of pipe, size of
pipe, number and type of fittings and valves must be
considered for minimum air pressure drop and opti-
mum efficiency of your compressor.
NOTE: Screw type compressors should not be
installed in air systems with reciprocating compres-
sors without a means of pulsation isolation, such as a
common receiver tank. We recommend both types of
compressor units be piped to a common receiver uti-
lizing individual air lines. See Figure 2.4-2.
When two rotary units are operated in parallel, pro-
vide an isolation valve and drain trap for each com-
pressor before the common receiver.
See Figure 2.4-3
To assure long trouble free operation of a compressor
operating with On-line/ Off-line and Auto Stop/Start
control, the system volume must be large enough to
keep the load/unload cycles to a minimum. This may
require the installation of a receiver down stream of
the compressor. Baseplate mounted units must be
piped to a receiver if installed in a system with insuffi-
cient volume to keep compressor cycling to a mini-
mum. If equipment such as filters or air dryers, is
installed in the main piping system, they must be
sized to handle the entire flow of the compressor and
an air receiver must be placed in the system between
the compressor discharge and the equipment,
regardless of system volume.
This will prevent quick cycling of the compressor
which results in large fluctuations in system pressure.
