Need help?
Do you have a question about the 6.72.1 and is the answer not in the manual?
Questions and answers
we have high difference in dp pressure and i will like to request some remedy .... thanks in advance !
High differential pressure in a Bollfilter with part number 6.72.1 is addressed by the following remedy:
- The controller monitors the differential pressure between the filter inlet and outlet.
- When the differential pressure reaches the set maximum value, the controller automatically triggers a backflushing process to clean the filter.
This process reduces the pressure by removing the accumulated soiling.
