CONTROL PIPING – Control piping is not necessary
since the Electra–Screw
piped for the control system specified.
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 en-
tering 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 in-
creased according to Inlet Line Length Chart
