8.2. Accessories
Accessories are available for compressor
directly from the manufacturer (by special
request in an order) or may be ordered
directly from the manufacturer at a later time,
see below. Individual accessories may be
combined.
Accessories not included in the standard
order must be ordered separately!
8.2.1. Central air pump intake kit
This kit provides a properly sized central filter
located on the compressor module with intake
ducts to the individual compressors. This
extends the central filter replacement interval
(now every 2,000 hours) and eliminates the
need to replace filters on individual
compressors with simple and fast replacement
of the central filter.
Compressor type Kit article no.

8.2.2. Set of compressed air outlet filters
The compressor may be equipped with a set
of filters if needed. A pressure regulator may
be added to the set of filters. The set of filters
is fully compatible with all compressors listed
above.
If a higher level of air filtration is
required, this specification must be
agreed upon with the supplier and
made clear in the order.

9. EQUIPMENT FUNCTION
DK50 9x4VRT/M
The compressor produces oil-free, dry,
filtered compressed air to power pneumatic
devices and equipment used in dental clinics
and laboratories, hospital departments and
more.
Compressor air pumps (11) draw in
atmospheric air through the inlet filters and
compress it through check valves and into the
compressed air system. From there, the
compressed air proceeds to the cooler (8), in
which the compressed air is cooled for the first
time and condensate is produced. The air
then passes through a water separator and
Fig. 2 Equipment function
into the condensing dryer (9). This continues
to lower the temperature of the air and
produces more condensate. The temperature
then rises to reduce the relative humidity. The
clean, dry air then passes through a check
valve and enters the air tank (2). Condensate
from the water separator and the dryer is
drained off into a 10 l vessel in the
condensate drain kit. The dryer ensures the
continuous and no-loss drying of the
compressed air. The treated compressed air
is then ready for additional use in the air tank.
