The Outdoor Series tanks were designed specifically with a patented controlled-action, double diaphragm assembly that is completely contained in a pre-pressurized air cushion. This unique design feature reduces condensation and regulates diaphragm action. Challenger is truly one-of-a-kind in that their tanks have a threaded nut for easy installation of a pump stand, a welded malleable elbow and an adjustable air charge. When achieving clean and airtight welds, we use the most modern welding equipment available for your convenience.
Additionally, we construct our diaphragms with an FDA approved high-grade butyl to achieve maximum quality. Challenger tanks’ true airflow design offers fewer issues with condensation. Our diaphragms positive lock internal clench ring is not able to slip and does not simply rely on the tank wall.This is because the tank contains a stainless steel port diffuser, and water connection, which directs the flow upward and then outward, all while locking the lower diaphragm in place.
For your convenience, all of our quality tanks are backed by a 5-year written, limited warranty. Our Challenger tanks are quality tested at four of our different stages on the production line. The tests include helium and high pressure to ensure the structural integrity of each and every tank.
