9. PRODUCT FUNCTION
9.1. Compressor with adsorption dryer
(Fig. 1, Fig. 2) The compressor air pump (1) draws in air through the inlet filter (8) and compresses
it through a non-return valve (3) and into a manifold, from which it is routed to the adsorption dryer
(9) through a connecting hose. From the inlet to the dryer module, the air is first cooled in the
integrated cooler (17) and then moves through the condensate separator (24), entering the active
chamber with adsorbent (19), where the air is dried. A portion of the air is fed into the second,
regeneration chamber, where this air is used to remove moisture from the adsorbent, after. The
active chamber switches on a cyclical basis. The dry air then passes through the non-return valve
(3) into the air tank (2).
* For DK50 4VR/50/M compressors, the manifold with the non-return valve is not used and the air
is routed directly to the air dryer.
9.2. Compressor cabinet
(Fig. 4) The soundproof cabinet provides compact covering of the compressor, dampens noise
efficiently, providing sufficient exchange of cooling air. With its design It can be placed in a dentist’s
office as a part of furniture. The fan (10) under the compressor pump provides cooling of the
compressor. It is in operation at the same time with the compressor motor or after switching on the
temperature switch at temperature above 40°C. After cooling the cabinet area approximately under
32°C, the fan turns off automatically. The dryer display (33) is located on the front panel of the
cabinet.
Risk of compressor overheating.
Make sure that there are no obstacles at the cooling air inlet into the cabinet
(around the bottom part of the cabinet) and at the hot air outlet on the top back
side of the cabinet.
If the compressor is placed on a soft floor, e.g. carpet, create space between the
base and the floor or the cabinet and the floor, e.g. underlay the footings with
hard pads to ensure sufficient cooling of the compressor.
