The Flex-Lite FL series’ improved CAD-2 diaphragm design is stronger and won’t crease and wear out like bag designs. It features a chlorine resistant 100% butyl diaphragm with a precision molded copolymer polypropylene lower water chamber for superior air and water separation.

This patented design allows each size tank to have a properly sized water chamber, matched to the drawdown performance of that tank. When it comes to performance and durability, the CAD-2 system cannot be beat.
