PRODUCT FUNCTIONALITY

Compressor with suction unit (Fig. 1)
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 pump 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 19.1).
The suction pump (36) (two aggregates on DUO2) draws in air, thereby creating vacuum in the
suction lines that are connected to the device and is a source of vacuum for removing foreign
substances from the doctor's work area. This air is then exhausted through an exhaust line routed
outside the operator's work area.
Compressor with suction unit and membrane dryer (Fig. 2)
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.

suction lines that are connected to the device and is a source of vacuum for removing foreign

Compressor with suction unit and 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).

outside the operator's work area.
Compressor cabinet (Fig. 4)
The soundproof cabinet provides compact covering of the compressor, allowing sufficient exchange
of cooling air. With its design It can be placed in a dentist's office as a part 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. Door of the casing with right
opening may be changed to left opening (see Chapter 12.2).
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.
