4.3 SERVICE AIR PIPING
Before installing the compressor, review the service
air system’s layout including: pipe sizes, auxiliary
separator tube, drip legs, line filter(s), and isolation
valves (See Figure 4-3).
PIPE SIZING
Pipes should be sized as a minimum to match the
dimensions of the compressor’s discharge
connection. All piping and fittings should be rated for
the discharge pressure.
AUXILIARY RECEIVER TANK
An auxiliary receiver tank should be installed in
systems where large demand fluctuations will occur.
 NOTE
Systems using both reciprocating and 
rotary screw compressors must isolate 
the two types from each other through the 
use of a common receiver tank. Air lines 
from each individual compressor should 
be connected directly to the common 
receiver tank.
