Dramatic improvement in utilization of operating personel
If you can imagine that with conventional screen changers every time the screens become blocked by contamination with traditional systems an operator must come and manually exchange screens.
With the POWERBACKFLUSH as the cleaning process is completely automated – Instead of the operator making 100-200 manual screen exchanges – He can be better utilized elsewhere in your extrusion plant. The automated backflushing will take care of screen cleaning each and every time the screens become blocked by contamination
Test results with a PowerBackflush screen changer -
In one trial the material was quite heavily contaminated therefore the system automatically cleaned screens by backflushing every hour. It was decided to stop the line and check the screens after four days of continuous running. On examination of the filter elements it was found that the screens had shown an extremely good level of cleaning With the result that there was still no need to change the screens even after 4 days of operation with highly contaminated material.
