Exhaust filter (oil mist separator)
NOTE
Please refer to the separate operating manual of the vacuum pump and
the exhaust filter!
The oil mist that is emitted by the vacuum pump in quantities that depend
on the working pressure must be led to the outside or to an exhaust hood
or similar. If this is not possible, the pump must be equipped with an
exhaust filter (oil mist separator).
• Observe the liquid level in the collecting vessel of the filter.
• Remove the condensate in time (please refer to the information
provided by the manufacturer in the separate operating manual).
