Durable Composite Construction - A rugged one-piece molded, inner-liner of premium high-density polyethylene. The outer-shell is impervious to rust, dents, and ultra-violet rays. The rigid molded polyethylene base is the sturdiest composite base on the market.

Proprietary Fiberglass Wrap Pattern - Tanks are stronger than if they were constructed with steel. Tanks can be installed with a wider range of pressure settings so you can select the system pressure you want.

Air Cell - The air cell is fabricated from durable and extensively tested ethyl-vinyl-acetate (EVA). EVA is resistant to chlorine and will not support iron bacteria growth that may be present in the water supply. It offers longer life than urethane air cells, or butyl diaphragms in steel tanks.

Replaceable Air Cell - With the tank installed! Air cell access is via a top mount design. Generous and accessible air cell opening facilitates easy removable and re-installation of replacement air cell.
