Service intervals filters

UD+ filters
The filter elements of oil mist filters (UD+) should be replaced after 4000 hours. The gauge or
pop-up is not a measure, as a typical oil mist filter operates in the steady state mode during its
life and this mode is e.g. 200-250 mbar.
Note that the indicator or gauge will not move into the red area but will stay yellow or orange
during operation.
Summarizing, the following service intervals should be observed (whatever comes first):
• 4000 operating hours
• 12 months in use
• Pressure drop: 350 mbar
