PRODUCT FUNCTIONALITY

Compressor (Fig. 2)
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 pumpis 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. 1)
The air pump (1) draws in atmospheric air through an inlet filter (8) and compresses it, feeding it
through the coolers (14) and the filter (15) into the dryer (9) and the dry, clean air is then fed
through the non-return valve (3) 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 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 pressure vessel does not need to be drained.
Compressor with condensation and filtration unit(Fig. 3)
The air pump (1) draws in air through an inlet filter (8) and compresses it through a non-return
valve (3) into the 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 collecting bottle. Compressed, oil-free filtered air is ready
for use.
Condensate must be drained from the air tank at regular intervals (see Chapter 19.1).
Compressor cabinet(Fig.4)
The soundproof cabinetprovides compact covering of the compressor, allowing sufficient
exchange of cooling air. With its design It can be placed in a dentist's office as apart of furniture.
The fan under the air pump of a compressor provides cooling of compressor and it is in operation
at the same time with an engine of the compressor. After prolonged use the temperature in the
cabinet may rise above 40°C, causing the cooling fan blower to automatically turn on. After
cooling the cabinet area down to 32°C the fan blower turns off automatically.
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 cabinet.
If placing the compressor on a soft floor such as carpet, create space for
ventilation between the base and floor or the cabinet and floor, e.g. underpin the
footings with hard pads.
For 8-10 bar compressor models, an hourly meter is installed on the pressure switch.
