Description
This vessel is engineered using Pentair’s signature fiberglass filament winding over a seamless, high-density polyethylene (HDPE) liner. The 3672 designation indicates a 36-inch diameter and a 72-inch sidewall height.
It is a “Media Tank,” meaning it is meant to be filled with loose filtration media (sand, carbon, or resin) and fitted with a top-mounted automatic or manual control valve.
