6. PRODUCT DESCRIPTION
6.1. Model variations and their uses
The compressor is used as a source of clean, oil-free compressed air to power dental equipment,
instruments and devices in laboratories where the parameters and properties of the compressed air are
suitable to the specific application.
Compressed air supplied by the compressor is unsuitable for use with artificial lung
ventilation devices without further filtration
Any use of the equipment outside the framework defined herein is considered inappropriate use. The
manufacturer is not liable for any damages or injury occurring as a result of inappropriate use.
6.2. Description
Compressor models are designed for the following uses:
DK50-10 Z compressor - a base-mounted compressor for stand-alone installation in a given space
DK50-10 Z/K compressor - a base-mounted compressor with a condensate and filtration unit (KJF1)
DK50-10 Z/M compressor - a base-mounted compressor with an air dryer
DK50-10 S compressor - an enclosed compressor with effective noise dampening for in-office installations
DK50-10 S/K compressor - an enclosed compressor with a condensate and filtration unit (KJF1)
DK50-10 S/M compressor - an enclosed compressor with an air dryer

6.3. Accessories
Accessories not included in the standard order must be ordered separately!
6.3.1 Automatic condensate drain
The automatic condensate drain (AOK) automatically drains condensate from the compressor’s air tank
based on a pre-set time interval. The condensate drain (AOK) is a suitable accessory for compressor
models without dryers.
6.3.2 Set of filters
Compressors may be equipped with a set of filters on the compressed air outlet if specified. The set of filters
may be equipped with a pressure regulator. Sets of filters are suitable accessories for all the compressors
specified above.
NOTE : If a higher level of air filtration is required, this specification must be agreed upon with the supplier
and made clear in the order.
6.3.3 Condensation and filtration unit (KJF)
The compressor may additionally be 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 compressed air circuit. The
compressed air is filtered at the same time.

7. PRODUCT FUNCTIONALITY
Compressor (Fig. 1)
The compressor aggregate (1) draws in air through an inlet filter (8) and compresses it through a check
valve (3) into an air tank (2) from which the appliance draws compressed air. If the pressure in the air tank
drops to the switching pressure, the pressure switch (4) turns on the compressor and the compressor
supplies compressed air to the air tank until it reaches the switch off pressure, at which time the compressor
switches off. The pressure hose is vented through the relief solenoid valve (13) once the compressor unit 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 18).
Compressor with membrane dryer. (Fig. 3)
The compressor aggregate (1) draws in air through an inlet filter (8) and compresses it, feeding it to the
cooler (14) through the filter (15) to the dryer (9) and the dry, clean air is then fed through the check valve
(3) into the air tank (2). A portion of the air bypasses the dryer with the captured moisture, which is
manifested as a gentle stream of air along the body of the dryer (9). Condensate from the filter is
automatically drained at regular intervals into the vessel via the condensate drain solenoid valve (16). The
dryer ensures continuous drying of the compressed air. The drain valve (7) drains condensate from the air
tank when drying performance is checked. Compressed, oil-free filtered air is stored in the air tank ready for
use.
The compressor with dryer requires no operator. The pressure vessel does not need to be drained.
Compressor with condensate and filtration unit (Fig. 2)
The compressor aggregate (1) draws in air through an inlet filter (8) and compresses it through a check
valve (3) into an air tank (2). Compressed air from the air tank flows through a cooler (10) that cools the
compressed air. The condensed moisture is trapped in the filter (11) and automatically separates as
condensate (12) into the vessel. Compressed, oil-free filtered air is ready for use.
Condensate must be drained from the air tank at regular intervals (see Chapter 18).
Compressor enclosure
The soundproof enclosure is compact and allows sufficient cooling air exchange. The design makes it
suitable for in-office installations in a way that blends in with other furniture. The fan under the compressor
aggregate ensures sufficient cooling for the compressor and runs with the compressor motor or when the
temperature switch is activated at temperatures above 40 °C.
Make sure that nothing impedes the free flow of air under and around the compressor.
Never cover the hot air outlet on the top back side of the case.
If placing the compressor on a soft floor such as carpet, create space for ventilation
between the base and floor or the box and floor, e.g. underpin the footings with hard
pads.
The 10 bar compressor model is equipped with an hour meter (Fig. 4).

OPERATION
In case of emergency, disconnect the compressor from the mains (pull out the mains
plug).
The compressor has hot surfaces.
Burns or fire may result if contact is made.
During prolonged operation of the compressor, the temperature in the box may increase
to over 40°C. At this point the cooling fan automatically switches on. After cooling the
space to under 32°C, the ventilator switches off.
Automatic start: when pressure in the tank drops to the pressure switch’s lower limit
level, the compressor automatically switches on. The compressor automatically switches
off after reaching the pressure switch’s upper limit level.
The working pressure settings for the pressure switch set by the manufacturer cannot be changed.
Compressor operation at a working pressure below the switching pressure indicates high air usage by the
attached appliance (see the Malfunctions chapter)
Required drying performance can only be achieved when following the defined operating
conditions!
Drying performance will decline and the achieved dew point will drop if the dryer is
operated at any pressure below the minimum working pressure!
The dryer will suffer damage if operated at ambient temperatures above the maximum
working temperature!
9. SWITCHING THE COMPRESSOR ON
(Fig. 5)
Turn the compressor on at the pressure switch (2) by rotating the
main switch (3) to the “I” position. Check the position of the breaker
switch, it must be in the “I” position. If it is in the “0” position, turn
the switch to the “I” position (Fig.3 – position 18). The switch (Fig. 4
– position 22) in the case of DK50-10 S/M 10bar compressors is on
the front side of the enclosure; the indicator lights up green. The
compressor switches on and begins to fill the air tank until the
pressure reaches the switching pressure and the pressure switch
turns the compressor off. The compressor then operates in
automatic mode and is controlled by the on and off pressure
settings on the pressure switch based on compressed air usage.
This pressure may be monitored on the pressure gauge (5). A
tolerance of 10% is acceptable. The pressure in the air tank may
not exceed the permitted operating pressure.
Changing the switching pressures on the pressure
switch is prohibited on any compressor.
The pressure switch (2) has been set by the manufacturer and further setting of switching on and off
pressure may be carried out only by a qualified expert trained by the manufacturer.
