If you are looking for the proven performance of a GWS steel tank in a lightweight composite design, C2-Lite CAD™ series is the answer. Efficient and cost-effective, C2-Lite CAD tanks are designed with the patented controlled action diaphragm design of GWS Challenger™ tanks.
 
Unlike other composite tanks that hide tired old bag technology in a plastic shell, the patented CAD-2 diaphragm design is stronger and will not crease and wear out. It features a 100% butyl diaphragm with a precision molded copolymer polypropylene liner for superior air and water separation. 
 
Available in sizes 60 litres to 450 litres
