PRODUCT DESCRIPTION
NP-DK50 2V 50, 2x2V 110-A-5_06-2020-MD 12 06/2020
Condensation and filtration unit
The compressor can be equipped with a condensation and filtration unit. The unit is used to cool the
compressed air from the air tank in the cooler, to capture condensate in the filter, to drain condensate
automatically from the pneumatic system and to filter the compressed air.
Equipotential bonding socket
The socket provides protective bonding. (Fig. 11)

8. PRODUCT FUNCTION
8.1. Compressor
Fig. 1 Air pump (1) sucks the atmospheric air in through the inlet filter (8) and compresses it through
the non-return valve (3) into the air tank (2) from which the device draws in the compressed air. If
the pressure in the air tank drops to the switch-on pressure, the pressure switch (4) switches the
compressor on and the compressor compresses the air into the air tank until it reaches the switch-
off pressure, when the compressor switches off. The pressure hose is vented through the solenoid
relief valve (13) once the compressor pump is switched off. The safety valve (5) prevents the
pressure in the air tank from rising above the maximum allowed value. The drain valve (7) drains the
condensate from the air tank. Compressed, oil-free filtered air is stored in the air tank ready for use.
Condensate must be drained from the air tank at regular intervals (see chapter 17.1).
