Compressor section
The compressor section contains the
following main parts:
• Air inlet with filter
• Air inlet silencer
• Temperature sensor
• Motor
• Drive unit
• Compressor
• Heat convector.
The air inlet is supplied with ambient air from
the inside of the dryer section, i.e. air that
has been filtered by the dust filters. This air
then passes through the air inlet with filter
and the air inlet silencer. The air is then
routed to the two-stroke compressor. The
compressor is powered by the electric motor
via the drive unit. The tension of the drive
belt is automatically adjusted.
The action of the compressor imparts heat to
the compressed air. To provide preliminary
cooling, the air flow is passed through the
heat convector before it enters the cooling
section.
The motor, compressor and heat convector
are cooled by the air stream forced through
the compressor section by the fan in the
dryer section. The temperature sensor
detects the ambient air temperature inside
the compressor section and activates the
temperature alarm if the compressor section
is overheated.
