<BR>Attention must be paid to the following points when connecting several compressors to a common (collective) line.

<BR>
<BR>Compressed air and condensate collective lines

1. Collective line with gradient.
    The line must be laid with a gradient of approx. 1.5 - 2 % in
    the direction of flow..
2. Connection line from above.
    The connection line must be connected to the collective
    line from above.
Compressed air collective lines

3. Water separator on longer rising lines.
    On longer lines that rise to a collective line a water separator
    with automatic drainage must be installed after the compressor
    in order to catch the water flowing back.

Vent collective lines

Points 1 and 2 also apply when vent lines are brought together in collective lines. Vent collective lines must also have an expansion vessel and vent silencer installed.
