INLET LINE - Where an inlet line is used between the air filter and the compressor, it must be thoroughly
cleaned on the inside to prevent dirt or scale from entering the compressor. If welded construction is
used, the line must be shot blasted and cleaned to remove welding scale. In either case, the inlet line
must be coated internally by galvanizing or painting with a moisture and oil-proof sealing lacquer. Up to
ten (10) feet (3 meters) in length, the inlet line should be the full size of the inlet opening on the
compressor. If an extra-long line is necessary, the pipe size should be increased according to Inlet Line
Length Chart Figure 2-4, page 13.
Accessibility for inlet air filter servicing must be considered when relocating the filters from the unit to a
remote location.
DISCHARGE SERVICE LINE - The discharge service line connection on both water-cooled and air-
cooled units is located at the right hand corner of the unit, viewed from the opposite end from control
panel side. When manifolding two or more rotary screw units on the same line, each unit is isolated by
the check valve in the unit discharge line. If a rotary screw unit is manifolded to another compressor, be
sure the other compressor has a check valve in the line between the machine and the manifold. If a
rotary screw and a reciprocating compressor are manifolded together, an air receiver must be located
between 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.
