Appropriate use
WOS water oil separators are intended for separating lubricant oil from
condensate from compressed air systems. This appliance must be used only for
the purpose for which it was specifically designed. All other uses are to be
considered incorrect.
The manufacturer cannot be held responsible for any damage resulting from improper,
incorrect or unreasonable use.
Use genuine spare parts only. Any damage or malfunction caused by the use of ungenuine
parts is not covered by Warranty or Product Liability.
Advanced dimensioning

Oil carry over (c) can be determined by measuring oil volume at two sequential compressor
services. In order to determine oil carry over compare initial volume of new oil with volume
of oil drained out of compressor at oil replacement. It is recommended to keep a record of
compressor services. When oil carry over is not known we suggest to use c(oil
carryover)=0,005g/Nm3.
