8.2.3. Filters set
Compressors may be equipped with a filters set on the compressed air outlet if specified. The set of
filters may be equipped with a pressure regulator. The sets of filters are suitable accessories for the
compressors specified above.
NOTE : If a higher level of air filtration is required, this specification must be agreed on with the
supplier and made clear in the order.

8.2.4. Condensation and filtration unit
The compressor may be additionally fitted with a condensation and filtration unit (KJF-1 or KJFR-1).
The KJF-1 or KJFR-1 ensure that the compressed air from the air tank is cooled in the cooler and
the condensate is captured in the filter and automatically separated from the pneumatic distribution
system. The compressed air is filtered at the same time.

PRODUCT FUNCTIONALITY
Compressor (Fig. 1)
The air pump (1) draws in atmospheric air through an inlet filter (8) and compresses it through a
non-return valve (3) into an air tank (2) from which the device draws compressed air. If the pressure
in the air tank drops to the switch-on pressure, the pressure switch (4) turns on the compressor and
the compressor supplies compressed air into the air tank until it reaches the switch-off pressure,
when the compressor switches off. The pressure hose is vented through the relief solenoid valve
(13) once the air pump is shut off. The safety valve (5) prevents the pressure in the air tank from
rising above the maximum allowed value. The drain valve (7) drains 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 19.1).
Compressor with membrane dryer (Fig. 2)
The air pump (1) draws in air through an inlet filter (8) and compresses it, feeding it to the cooler
(14) through the filter (15) and the check valve (3) into the dryer (9), and feeds the clean and dry air
into the air tank (2). A part of the air is released from the dryer with the captured moisture, which is
manifested as a light air stream along the body of the dryer (9). Condensate from the filter is
automatically drained at regular intervals into the collecting bottle via the condensate drain solenoid
valve (16). The dryer ensures continuous drying of the compressed air. The drain valve (7) drains
