HCF Series Sand Filters
Product Description

The HCF Series Filters feature an improved internal and external design that enhances performance and endurance. The filters distribute water more evenly with a multi-diffuser configuration, increasing filter cycles, effectiveness, and longevity of the filter. Installation and maintenance are easier than ever before. A transparent manway simplifies operation and the UV-protected and infusion molded fiberglass shell reduces corrosion and shields the unit from the elements, such as blooming and biofilm build up.

  • High performance filtration and longer service life
  • Transparent manway design simplifies operation
  • Dual-Head (HCF230) or Quad-Head (HCF234 and HCF236) Diffusers provide optimized water distribution
  • Commercial-grade PVC and ABS injection-molded internals with 360° slotted lateral provide high performance and resistance in corrosive applications
  • Industrial valve and pressure gauge configuration offer durability and increased accuracy
  • 34″ model fits through standard 36″ doorways with no need to remove the door frame, simplifying replacement installations
  • New warranty policy; 5-year parts, 1-year labor
