Patented Flex-Tube™ Filter Elements

are at the core of active regenerative filtration.  Their pore size is variable. During filtration the pore is smallest creating a retentive support for the diatomaceous earth filter-aid.

Pneumatic "bump" mechanism

one of the innovations that allows filter elements to be cleaned without using any backwash water....not a drop
