Original LPD-250 New Aluminum Body - Only 17 lbs
 
LPD-250 Series Dechlorinating diffuser

Already widely used throughout the United States and Canada, the LPD-250 is the easiest dechlorination device available. Simply fill the feed tube with tablets and the LPD-250 will do the rest. There is no chemical to mix and waste. The LPD-250 is for use with chemically treated (4 ppm or less chlorine/chloramine) potable water. For higher chlorine concentrations up to 300 ppm please see our  COMBO KITWeighing 33 lbs., the original orange LPD-250 is heavy enough to take the day-to-day abuse of flushing. You can flush straight off a hydrant or attach a hose to point the flow where you want it to go.  The new Aluminum body yellow LPD-250ALUM has the same rugged and efficient design but weighs half as much.  This is good for reducing strain on the hydrant nozzle and swivel during direct hydrant flushing.  Is equipped with a pitot slot for measurement of discharge flow rate as well as a LPD-Pitotholder to hold the Pitot in the optimal position for readings.

 
 
CHOICE OF TABLETS

The LPD-250 uses either LPD-Chlor tablets (contains Sodium Sulfite 81.3%) or Vita-D-Chlor Tablets (Ascorbic Acid-Vitamin C) which neutralizes the chlorine/chloramines in the water you are flushing. When using LPD-CHLOR tablets, the LPD-250 consumes about 1 tablet per 2,500 gallons - the feed tube should be topped off with additional tablets after each increment of about 10,000 gallons of flow. The LPD-Chlor tablets are specifically manufactured for use in the LPD without the need for a tablet screen. The diffuser can handle about 10,000 gallons between tablet recharge.

LOW OR HIGH FLOW DECHLORINATION

We recommend a Bracket for higher GPM Flushing (600+) if you are using a hose!

The LPD-250 can handle flows from 200 to 1382 GPM and hydrant pressures up to 200 psi. For flows lower than 200 gpm, we recommend you use our Low Flow Inserts which will allow more water to run past the tablets, great for applications such as pool draining. Hydrant wyes are available in 4 or 4.5 NST and allow you to use 2 LPD-250s off the pumper nozzle.
