The 3M H₂0 Neutralizer features flow ranges from 5 - 1,200+ GPM. It's lateral by-pass venturi design achieves a full vacuum at pressures as low as 20 psi and maintains a constant feed solution flow of one gallon per minute throughout the entire flow range. The 3M can be used for both efficient chlorination, as well as dechlorination. No-chlor ascorbic acid for dechlorination is also available.

The 5M H₂0 Neutralizer features flow ranges from 500 - 4,000 GPM. It's lateral by-pass venturi design achieves a full vacuum at pressures as low as 20 psi and maintains a constant feed solution flow of one gallon per minute throughout the entire flow range. The 5M can be used for both efficient chlorination, as well as dechlorination. No-chlor ascorbic acid for dechlorination is also available.
