Flexcon Industries’ composite Flow-Thru tanks for constant pressure water systems incorporate a patented water vane, which circulates water in the tank, preventing the possibility of stagnant water. Constructed of a co-polymer polypropylene, which is wrapped with a continuous fiberglass fiber immersed in epoxy, these tanks are corrosion resistant, lightweight and include the company’s patented CAD2 diaphragm. Available in 15-, 22-, 38- and 50-gallon (56.78, 83.27, 143.84 and 189.27 liter) sizes through the company’s professional wholesale distribution network. http://www.flexconind.com
