Specifications:

  • CHECK OUT THE RELATED-ITEMS TAB ABOVE FOR ACCESSORIES AND PELLETS!
  • Dry Pellet In-Line Chlorinator Model 400 is designed for well water applications, not pools like others online
  • For best results and consistent chlorine dosing we recommend a contact tank be installed after the Chlorinator to give some time after the chlorine has been injected
  • After contact tank to remove chlorine residual if desired install a low cost whole house carbon backwash filter for clean water throughout the house!
  • If being used for residential applications, a whole-house carbon filter is recommended after the contact tank.
  • The Model 400 dry chlorine pellet feeder is designed to operate with a standard well pump and pressure tank, up to 75 PSI.
  • If you have a variable speed well pump that delivers "constant pressure”, you must use the optional Feed Rate Valve (see Related Items tab).
  • No messy chemicals; no moving parts; no electricity required.
  • Corrosion-proof construction.
  • PVC Construction from all NSF-certified materials. PVC used in the Model 400 is NSF certified for drinking water.
  • Adjustable metering of chemicals. Fast and easy refilling.
  • Never needs priming.
  • Holds about 4 lbs of 3/8" pellets in one filling.
  • One filling with pellets will typically treat 15,000 to 20,000 gallons of water before requiring refilling.
  • For best results use the Sentry 3/8" 1 gram pellets.
  • When adjusted to the #1 hole setting, the unit should dispense approximately 2.0 ppm of chlorine and the system should process approximately 15,000 to 20,000 gallons of water before needing to be refilled.
  • Easy to install.
  • Note: For gravity or non-pressure tank installations, the optional Feed Rate Valve must be ordered separately. See below.
  • For best results, use a contact tank and carbon filter after the Model 400.
  • Includes two 1-1/2" PVC slip unions plus two 3/4" NPT (threaded) unions.
  • If you have 1" or 1-1/4" pipe, you can purchase bushing reducers to go from 1-1/2" to your pipe size at most hardware stores

  • NOTE:While this is feeder is made from FDA Approved Materials, it is not NSF Certified. If your application is a commercial application requiring NSF certification please contact us for a liquid bleach feeder pump.
