7. FUNCTION

Compressor

(Fig.1, Fig.2)

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 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 an 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 dryer M2

(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 an output filter (17) and check valve (3), sending clean, dry air into the air tank (2). After each
switching off of the compressor using the pressure switch the adsorber is regenerated while the drier
chamber is depressurized. Air escapes from adsorption chamber through the open solenoid valve (21),
while it is concurrently blown with dried air. Air drying takes place in one chamber and regeneration takes
place in the other chamber. The mode of the chambers is changed in regular cycles and the drying and
regeneration process takes place in the chambers in a reversal order. The entrapped water shall be pushed
out via a water separator. Dry, clean compressed air free from oil traces is stored in the air tank ready for
use.

Compressor with condensation and filtration unit KJF1, KJF2

(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.6,Fig.7)

The box is soundproof and allows sufficient exchange of cooling air. With its design it is suitable for location
in rooms where reduced noise level is required. Fan under compressor aggregate provides for the
compressor cooling. It is in operation at one time with compressor engine, or when temperature in the casing
rises above 40°C. After the space in the casing cools down under ca 32°C, fans shall get automatically
switched off.

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.
