6. PRODUCT DESCRIPTION
6.1. Model variations and their uses
Compressors are the source of clean, oil-free compressed air used to drive dental appliances and
equipment.
Compressors models are designed for the following uses:
Dental compressors DK50 2V/50 - are designed for independent placement of the compressor in any
area.
Dental compressors DK50 2V/50/M - are designed for independent placement of the compressor in any
area and feature an adsorption air dryer M3.
Dental compressors DK50 2V/50S - feature soundproof boxes suitable for placing in the dentist‘s
surgery.
Dental compressors DK50 2V/50S/M - feature soundproof boxes and an adsorption air dryer M3.
Dental compressors DK50 4VR/50 - These compressors can be situated in areas where their operation
and noise will not disturb their immediate surroundings. They are capable of providing compressed air for
several dentists‘ surgeries.
Dental compressors DK50 4VR/50/M - are equipped with an adsorption air dryer M2.
Dental compressors
DK50 4VR/50S - are placed in compact soundproof boxes and are capable of
providing compressed air for several dental units.
Dental compressors DK50 4VR/50S/M - are placed in compact soundproof boxes and are equipped with
an adsorption air dryer M2.

Without additional filtration equipment, the compressed air from a compressor is not suitable
for the operation of breathing appliances or similar equipment.
7. FUNCTION
Compressor (Fig.1)
The compressor (1) draws in air through a filter (8) and compresses it through a check valve (3) into an air
tank (2). The connected apparatus draws the compressed air from the air tank until the pressure drops to a
default preset level on the air-pressure switch (4) switching the compressor on. The compressor again
compresses air into the nozzle until the maximum pressure is reached and the compressor switches off.
After compressor aggregate is switched off, pressure hose shall be pressure-release solenoid valve (21).
Safety valve (5) prevents the pressure in air chamber from rising above the maximal allowed value. The
drain valve (7) releases the condensate from the air nozzle. Compressed, clean air free from oil traces is
stored in the air tank ready for use.
Compressor with dryer M2, M3 (Fig.2, Fig.3)
Compressor aggregate (1) sucks the atmospheric air through input filter (8) and it supplies it compressed to
the cooler. Air further proceeds via condensate trap through control valve (12), through drier chamber (9)
with adsorber (18), where humidity is captured , through output filter (16) and a check valve (3) to air
chamber (2). After each switching off of the compressor using the pressure switch the adsorber is
regenerated while the drier chamber is depressurized. Air escapes from adsorption chamber through the
open solenoid valve (10), while it is concurrently blown with dried air. Air drying takes place in one chamber
and regeneration takes place in the other chamber. The mode of the chambers is changed in regular cycles
