Figure 6- 5 – DETAILED WATER SEPARATOR AND DRAIN
The separator (4) removes the liquid water from the compressed air stream by inertial effects and
collected in a lower bowl (3). The collected water is evacuated by a float-type drain valve (1). The device
prevents the loss of compressed air by only allowing the discharge of liquid water during its opening
phase. An isolation ball valve (5) is provided between the separator bowl (3) and the drain valve body
(1). This allows the safe and quick removal of the drain valve for servicing, in case the drain valve
malfunctions.
In case the drain valve is fouled with dirt, cleanse the collection bowl also:
1. Be sure the unit is completely off and oil sump is depressurized.
2. Disconnect, lockout and tagout power supply to the compressor package.
3. Close (when provided) valve isolating compressor package from air system.
4. Unscrew drain valve (1) from isolation valve (5).
5. Unscrew collection bowl (3) from separator housing (4).
6. Inspect and clean collection bowl and sealing o-ring.
7. Reinstall in reverse order. If the vent adaptor has been removed from the bowl, note its location and
orientation in relation to the bowl (5) – see detail Figure 6-5. The long end of the black tube attached
to the vent adaptor must protrude upward into the bowl (5) during installation. This is necessary to
promote adequate gas venting during liquid drainage.
