Condensate drains, typical example
Location of electronic condensate drains
GA Workplace and Workplace Full-Feature compressors have an electronic water drain (EWD). The
condensate from the air cooler accumulates in a collector. When the condensate reaches a certain level, it is
discharged through drain outlet (Da).
On GA Workplace Full-Feature compressors, an additional electronic water drain (EWD1) is provided. The
condensate from the separator of the dryer is collected by water drain (EWD1) and discharged through drain
outlet (Da1).
.
Testing the electronic water drain can be done by pressing the test button (1) on top of the drain.

Regulating system
Description
If the consumption is less than the air output of the compressor, the net pressure increases. When the net
pressure is higher than the set-point (desired net pressure), the regulator will decrease the motor speed. If the
net pressure keeps on rising when the motor runs at minimum speed, the regulator stops the motor. If the
motor is stopped automatically and the net pressure approaches the set-point, the regulator will restart the
motor.
