8. PRODUCT DESCRIPTION
8.1. Prevedenia
Compressor models are designed in the following variants:
oil-free compressor embedded on a base covered with a compact
housing with an efficient noise suppression.
Upon customer request the compressor is provided with rubber feet or casters (2 with brakes (22) in
front and 2 without brakes (23) in the back).
Without additional filtration equipment, the compressed air from a compressor is
not suitable for the operation of breathing devices or similar equipment.
he compressor is not equipped with an emergency power supply.
9. FUNCTION
(Fig.1)
The compressor (1) draws in air through a filter 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. Safety valve (5) prevents the pressure in air chamber from rising
above the maximal allowed value. The drain valve (8) releases the condensate from the air
nozzle.
The soundproof box is compact yet allows sufficient exchange of cooling air. Fan (6) provides for
the compressor cooling. After a prolonged operation of a compressor, temperature in the casing
can rise above 40°C, at that time the ventilator shall be in operation also after the compressor is
switched off after the space within the casing is cooled down under ca 32°C. Fastener (14)
ensures the power cord and its possible release from the connector (10).
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 .
