B. The condensate flows through the feed line (1) into
the condensate drain and accumulates in the housing
(2). A capacitive sensor (3) continuously registers the
liquid level. As soon as the container is filled, a fixed
waiting period begins during which more condensate
accumulates. After the waiting time has expired the
pilot valve (4) is then activated and the diaphragm
(5) opens the outlet line (6) for discharging the
condensate.
When the condensate drain has been emptied, the
outlet line is closed again quickly and tightly without
wasting compressed air.
