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 (13).
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 membrane dryer (Fig.2, Fig.3)
The compressor unit (1) pulls in outside air through the inlet filter (8) and compresses it through the cooler
(14), filter (19) and micro-filter (18) to the dryer (9) and on through the check valve (3) as dry clean air in the
air tank (2). Condensate from the filter and micro-filter is automatically drained into the collection vessel. The
dryer provides continuous drying of the compressed air. Dry, clean compressed air free from oil traces is
stored in the air tank ready for use.
Compressor with condensation and filtration unit (Fig.5)
The compressor (1) draws in air through a filter (8) and compresses it through a check valve (3) into an air
tank (2). The compressed air from the nozzle 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). Dried,
clean compressed air, free from oil traces, is ready for use.
Compressor box (Fig.4)
The soundproof box is compact yet allows sufficient exchange of cooling air. It can be placed in a dentist’s
office. The ventilator under the aggregate 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
case may rise above 40°C, causing the cooling fan blower to automatically turn on. After cooling the case
area to 32°C the fan blower turns off automatically. Door of the casing with right opening may be changed to
left opening (see Chapter 9).
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.
