20 Gallon - Rolled Steel - Outdoor Series
Outdoor installations demand a tank that can withstand intense UV exposure, rain and every- thing else nature has to offer. Sealed with 8-10 mils of high mastic (solids) epoxy coating, and a two-part urethane finish, this series has the best salt spray and UV characteristics available on the market. Challenger water tanks feature CAD-2 technology (Flexcon famous controlled action diaphragm system) at a very affordable price. In short, you get superior air and water separation and unmatched performance.
Our patented manufacturing technique allows Flexcon to properly size the diaphragm in a full range of sizes from 14 to 119 gallons. Every Challenger tank undergoes a seam-weld test, high-pressure test, and is subjected to our famous helium test. Before leaving the factory, a final air charge check insures each tank arrives at the job site with the correct pre-charge. Flexcon stands behind every Challenger tank with a five-year warranty.
