Filter configuration

 

The Filterwell system is a combination of an internal screened pipe and an external slotted jacket pipe with a granular uPVC filter medium located in the gap between the two. Granule pack is a normal screened pipe covered with a bonded uPVC granular filter medium. The structure of Gravelpack is similar to  the Gravelpack with the exception of the filter medium comprising of specialized fine-grained sand.
