Compressed Air Applications Manual | Configuration of a compressed air system
Distribution
The compressed air distribution network
is divided into:
• the main pipe (MP)
• distribution pipes (DP), and
• connecting pipes (CP)
It is advisable to organize the pipe net-
work according to function and use.
MP
CP
DP
The pipe joints should be continuity
bonded in order to prevent leaks in the
distribution system. Flange joints and
screwed connections should preferably
be avoided. Clamped connections for
plastic pipes should be pressure- and
vacuum-tight and designed to function
without elastomer seals.
∆ pnetwork ≤ 0.1 bar
Generation
7 bar
MP
∆p = 0.03 bar
Point of use
∆pmax = 0.9 bar
6 bar
CP
∆p = 0.04 bar
DP
∆p = 0.03 bar
The pressure loss from the receiver to
the point of use should not exceed 0.1
bar.
With an optimum layout of the pipe net-
work, the pressure loss is assumed to
be:
0.03 bar for the main pipe (MP)
0.03 bar for the distribution pipes (DP)
0.04 bar for the connecting pipes (CP)
The total pressure loss of the system
– including filters, separators, dryer,
maintenance units and connecting hoses
– should not exceed
1.0 bar.
To realize an operating pressure of 6 bar
at the point of use, it will therefore be ne-
cessary to produce a pressure of 7 bar at
the compressor station
∆ ptotal ≤ 0,1 bar
