    Instruction book OSD oil/condensate separator (optional) OSD unit Oil/condensate separators Compressed air leaving oil-injected compressors contains oil. During cooling of this air, oil-containing condensate is formed. OSD are designed to separate the major part of this oil from the condensate and to catch the oil in a collector.

  • Page 116: Operating And Maintenance Instructions

    Instruction book Operation Condensate containing fine oil droplets flows via a strainer (5) through filter (3), in which the droplets coalesce into larger drops. The condensate is then led to vessel (1) where the oil rises due to the difference in specific mass.
