Description

Our Pentair Rainbow 320 is an in-line tablet feeder that automates chlorination on the return line—after the filter and heater—so water stays consistently sanitized without daily hand dosing. The top-loading, sealed chamber keeps fumes contained while the external control valve lets us fine‑tune feed rate for steady residuals. It’s a clean, low‑touch way to keep pools clear through hot spells and busy swim weekends.

Key Features

  • In‑line install on the return line for hands‑off, consistent tablet feed.
  • Top‑loading, sealed canister for safe, easy refills.
  • External control valve for precise chlorination adjustments.
  • Accepts slow‑dissolving 3" trichlor or 1" trichlor/bromine tablets.
  • 2" slip ports with bushings for 1½" PVC—easy tie‑in on most pads.
  • NSF listed when used with Rainbow flow‑indicating device (R172276).
