Intervals for Changing the Filter Element

To monitor the degree of contamination in the filtration unit it is equipped with an optical
clogging indicator.

If  the  clogging  indicator  is  red,  the  differential  pressure  is  too  high,  indicating  that  the
filter  element  is  used  up  and  must  be  changed.  The  colour  green  indicates  that  the
differential pressure over the filter element is < 2.5 bar for OFT20 and <2 bar for OFT-HV
and filtration will take place.
