Description
Product Description
The 3672 (36″ diameter x 72″ height) is manufactured using a seamless high-density polyethylene (HDPE) inner shell reinforced with high-strength fiberglass and epoxy resin.
This vessel is typically used in “multi-media” setups (sand, carbon, or resin) where high flow rates and large dirt-holding capacities are required. The 4-inch threaded opening makes it compatible with most commercial-grade automatic control valves.
Key Features
-
Superior Chemical Resistance: The HDPE liner is impervious to the salts, acids, and chlorine common in water treatment.
-
4″ 8-UN Threaded Opening: A precision-molded top opening that fits high-flow valves like the Runxin F74/F77 or Fleck 2850/2900 series.
-
Food-Grade Certified: Safe for potable (drinking) water applications.
-
Lightweight Alternative: Much easier to transport and install than traditional steel pressure vessels while maintaining a 10.5 Bar pressure rating.
