isolated by the check valve in the unit discharge line. If
a rotary screw unit is manifolded to another compres-
sor, be sure the other compressor has a check valve in
the line between the machine and the manifold. If a
rotary screw and reciprocating compressor are man-
ifolded together, an air receiver must be located be-
tween the two units.
Discharge air used for breathing will
cause severe injury or death. Consult
filtration specialists for additional
filtration and treatment equipment to
meet health and safety standards.
The oil–free air discharging from the EWD package is
saturated with water vapor at discharge temperature.
An air dryer may be required if the air is used in a mois-
ture sensitive process. In addition, the compressed air
has been mixed with contaminants that entered the in-
take of the compressor.
COMPRESSOR WATER DRAIN – The compressor
drain port should be connected to a floor drain. The
drain line must slope downward away from the unit to
allow excess condensate to flow by gravity. As neces-
sary the automatic water management system will
open the drain solenoid valve to drain excess water.
Since the compressor may be at operating pressure
and temperature when the drain solenoid valve opens,
the hot water will spray out of the compressor water
drain port at high pressure. It is recommended that the
compressor water drain port be hard piped to the floor
drain.
