9. PRODUCT FUNCTION
9.1. Compressor
The air pump (1) draws in atmospheric air through an inlet filter (8) and compresses it through a
non-return valve (3) into an air tank (2) from which the device draws compressed air. If the pressure
in the air tank drops to the switch-on pressure, the pressure switch (4) turns on the compressor and
the compressor supplies compressed air into the air tank until it reaches the switch-off pressure,
when the compressor switches off. The safety valve (5) prevents the pressure in the air tank from
rising above the maximum allowed value. The drain valve (7) drains condensate from the air tank.
Compressed, oil-free filtered air is stored in the air tank ready for use.
Condensate must be drained from the air tank at regular intervals (see Chapter 18.1).
9.2. Compressor with membrane dryer
The air pump (1) draws in air through an inlet filter (8) and compresses it, feeding it to the cooler
(10) through the filter (18) and the non-return valve (3) into the dryer (9), and feeds the clean and
dry air into the air tank (2). A part of the air is released from the dryer with the captured moisture,
which is manifested as a light air stream along the body of the dryer (9). Condensate from the filter
is automatically drained at regular intervals into the condensate collection vessel (12) via the
condensate drain solenoid valve (17). The dryer ensures continuous drying of the compressed air.
The drain valve (7) drains condensate from the air tank when drying performance is checked.
Compressed, oil-free filtered air is stored in the air tank ready for use.
For the membrane dryer to work as intended, the dryer is connected directly to the air tank without
the use of a check valve. As the membrane dryer contains selective membrane fibres, there is a
small amount of air leakage through them (about 0.5 bar/30 min)
This is why there is a gradual, slow drop in pressure even when there is no demand for compressed
air (from the air tank), however, this is not a malfunction.
The pressure vessel does not need to be drained.
9.3. Compressor cabinet
The cabinet serves as a compact soundproof compressor enclosure and ensures the sufficient
exchange of cooling air. The fan under the air pump (11) and the cabinet fans (21) cool the
compressor. The fans run concurrently with the compressor motor or when the temperature switch
is activated at a temperature higher than 40°C. Once the space in the cabinet cools down to about
32°C, the fans turn off automatically.
