Instruction Manual Oil-Less Compressors
3.2. FUNCTIONAL DESCRIPTION OF FINAL SEPARATOR
A final separator is mounted after the three first stages of the single-stage oil-less compressor and after the
second stage of the 2-stage oil-less compressor.
Separation is achieved by means of centrifugal action provided by a baffle (4). A sintered metal filter (2) is
provided additionally to remove dirt contamination.
3.2.1. CONDENSATE DRAIN
1-stage compressor (option)
The condensate has to be drained manually every 15 minutes during operation and after each operation. At
increased humidity, intervals for draining may be shorter. Therefore open knurled nut mounted on lower part of
separator housing. After draining the condensate, firmly tighten knurled nut.
Compressors equipped with a condensate drain valve are drained automatically. Ensure that the filters are
drained every 15 minutes. At increased humidity, intervals for draining may be shorter.
2-stage compressor (std.)
The condensate has to be drained manually every 15 minutes during operation and after each operation. At
increased humidity, intervals for draining may be shorter. Therefore open knurled nut mounted at the lower part
of separator housing. After draining the condensate, firmly tighten knurled nut.
Compressors which are equipped with a condensate drain valve are drained automatically. Ensure that the filters
are drained every 15 minutes. At increased humidity, intervals for draining may be shorter.
3.2.2. FINAL SEPARATOR MAINTENANCE
Maintenance process is the same as for intermediate separator, see chapter 3.1.2.
