2. INFORMATION ON PRODUCT
2.1. Usage on purpose
•
This medical compressor, hereinafter referred to as the compressor, is the source of clean, oil-
free pressurized air for use with respiratory equipment. Due to the silent operation of the
compressor, it is possible to place the unit near the respiratory appliance beside the bed of the
patient.
The compressed air from the compressor is suitable for the operation of respiratory
appliances or similar apparatus.
•
The compressor is to be operated in dry, aerated rooms where the ambient temperature is
b15°C and +40°C, with the relative air humidity not exceeding 70%.
•
The compressor must not be exposed to rain. The appliance must not be used in humid or wet
environments. Furthermore, it is forbidden to use it in the presence of flammable liquids or
gasses.
•
Prior to the connection of compressor to the respiratory appliance, it is necessary to assess
whether the available medium meets the requirements of the given appliance of use. Please,
refer to the technical data for this purpose.
•
Usage, other than the compressors intended use is not considered to be safe. The
manufacturer is not responsible for the damages implied if the compressor is used for other
uses. Such a risk is assumed only by operator/user.

The appliance consists of an oil-free piston compressor driven by a single-phase electric motor, of
an filtering and drying equipment, of an pressure tank and of a pressure regulator. The
compressor is placed in a box lined with noise reducing material. The appliance thus produces
filtered compressed air without any traces of oil with reduced humidity contents.
The air pump (19) sucks the atmospheric air through filters (A), (B). Compressed air is cooled in
the cooler (15), continue in the filter (C) and condensed liquid from the water trap (14) is
automatically released to the evaporative tray (20). The air continue through the check valve to
the pressure tank (11) and through the pressure regulator (13) with filter (D) to the output (10).
The fans operate while the air pump (19) works, or also during the pause, when the temperature
in the cabinet is over 40°C. Any increase of temperature in the cabinet over 80°C (cooling failure)
is signalled by the red indicator (3) and by acoustic alarm. The pressure switch (16) control
running the air pump (19) according to pressure in the pressure tank (11). A safety valve (17)
prevents the maximal allowable pressure in the pressure tank.
