Do not use the compressor
to support the discharge pipe.
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 optimum efficiency of your compressor.
It is essential when installing a new compressor to review
the total plant air system. This is to ensure a safe and
effective total system.
Liquid water occurs naturally in air lines as a result of
compression. Moisture vapor in ambient air is
concentrated when pressurized and condenses when
cooled in downstream air piping.
Moisture in compressed air is responsible for costly
problems in almost every application that relies on
compressed air. Some common problems caused by
moisture are rusting and scaling in pipelines, clogging of
instruments, sticking of control valves, and freezing of
outdoor compressed air lines. Any of these could result in
partial or total plant shutdown.
Compressed air dryers reduce the water vapor con-
centration and prevent liquid water formation in
compressed air lines. Dryers are a necessary companion
to filters, aftercoolers, and automatic drains for improving
the productivity of compressed air systems.
NOTICE
!
2.3 PIPING (Continued)
A dripleg assembly and isolation valve should be
mounted near the compressor discharge. A drain line
should be connected to the condensate drain in the
base.
IMPORTANT: The drain line must slope downward from
the base to work properly.
NOTE: For ease of inspection of the automatic drain trap
operation, the drain piping should include an open funnel.
It is possible that additional condensation can occur if the
downstream piping cools the air even further and low
points in the piping systems should be provided with
driplegs and traps.
IMPORTANT: Discharge piping should be at least as
large as the discharge connection at the compressor
enclosure. All piping and fittings must be suitable for the
maximum operating temperature of the unit and, at a
minimum, rated for the same pressure as the
compressor sump tank.
