pneumatic tubes and hoses for deposits.
If deposits are detected, perform the following:
− Change or clean valves, coolers, separators, purifiers,
and all pneumatic tubes and hoses from deposits.

TELESCOPIC INTAKE TUBE
The telescopic intake tube has to be inserted in opening 5,
Fig. 27. It is necessary to ensure clean air. Petrol driven
breathing air compressor units are fitted with a telescopic in­
take tube supplied with the unit. The use of it is also recom­
mended for electric power driven units.

4.4.3. INTERMEDIATE SEPARATOR

DESCRIPTION
An intermediate separator is mounted on the compressor be­
tween 2nd and 3rd stage. It is designed to remove water and
oil accumulating due to cooling the compressed medium
down after the compression process.
Separation is achieved by means of centrifugal action pro­
vided by a vortex plate.
INTERMEDIATE SEPARATOR MAINTENANCE
Proper operation will rely on the intermediate separator
being properly serviced.
Open drain tap (1, Fig. 28) and drain off condensate every 15
to 30 minutes during operation.
