DISCHARGE SERVICE LINE
- The discharge service line connection on both water-cooled and air-
cooled units is made at the right hand corner of the unit, viewed from the opposite end from control panel
side. When connecting two or more GD rotary screw units on a common manifold, each unit is isolated
by the check valve in the unit discharge line. If a Gardner Denver rotary screw unit is connected to
another compressor on a common manifold 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 connected
together on a common manifold, 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.
BLOWDOWN VALVE PIPING
-
The blowdown valve is piped back into the airend between the inlet valve
and air filter.
