8. 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 dryer M1.10 (Fig.2, Fig.4)
The compressor (1) draws in air through a filter (8) and sends it to the air dryer in compressed form. The air
proceeds through the cooler (15) and through the dryer chamber (9) with dessicant (16). The moisture is
captured in a
output
filter (17) and check valve (3), sending clean, dry air into the air tank (2). Adsorber shall
be regenerated after every switching off of compressor using pressure switch during dryer chamber
depressurisation. Air escapes from adsorption chamber via open solenoid valve (14), while it is concurrently
blown with dried air. The dessicant is regenerated and the captured water from the chamber flows out
through the drain valve. Dry, clean compressed air free from oil traces is stored in the air tank ready for use.
Additional dryer regeneration - without case (Valid for M1.10)
To ensure efficient operation of the dryer, the dessicant must be regnerated twice a month. Open the valve
for additional regeneration (19) for 8 hours. During this time the dessicant shall regenerate, ensuring its high
efficiency for the life of the dryer. After this time of forced regeneration it is necessary to close the
regeneration valve by (fine) clockwise rotation.
Additional dryer regeneration - in a case (Valid for M1.10) (Fig.5)
For the compressor with dryer MONZUN M1.10 in a case, the valve operation for regeneration (19) connects
through a flexible spindle to the front panel of the case. To ensure efficient operation of the dryer, the
dessicant must be regenerated twice a month. Open the valve for additional regeneration by turning the
button (21) from position "0" to position "I" to the left (counterclockwise) for 8 hours. After the regeneration is
complete, close the regeneration valve by turning the button from position "I" to position "0" (clockwise).
Compressor with dryer M1a (Fig.3)
The compressor (1) draws in air through a filter (8) and sends it to the air dryer in compressed form. The air
proceeds through the cooler (15) and through the dryer chamber (9) with dessicant (16). The moisture is
captured in a
output
filter (17) and check valve (3), sending clean, dry air into the air tank (2). Adsorber shall
be regenerated after every switching off of compressor using pressure switch during dryer chamber
depressurisation. Air escapes from adsorption chamber via open solenoid valve (14), while it is concurrently
blown with dried air. The level of drying of the passing-through air is monitored by a humidity sensor (23),
that shall open the regeneration valve (24) in the case of registering humidity exceeding the set humidity and
at the time of a pause of the compressor it shall automatically regenerate the drying agent in the chamber.
The entrapped water from the chamber shall be pushed out via a valve. Dry, clean compressed air free from
oil traces is stored in the air tank ready for use.
Compressor with condensation and filtration unit (Fig.7)
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.5, Fig.6)
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.
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.
