Flex-Lite Series - Composite Well Pressure Tank - FL7

The Flex-Lite FL7 is a corrosion-proof well pressure tank that is made with a composite of continuous strand fiberglass filament that is coated with epoxy. The Flex-Lite FL series features the improved CAD-2 (Controlled Action Diaphragm) design which is stronger and doesn't crease and wear out like older bag designs. The 100% butyl diaphragm is chlorine resistant and combined with the precision molded co-polymer polypropylene lower water chamber provides 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.So if you are looking for the proven performance of a Flexcon steel tank in a lightweight composite design, Flex-Lite FL is the answer.
