UNF Neutralizing Filters

Neutralizes and Raises pH of Acidic Water

IDEAL FOR HARD WATER APPLICATIONS WITH LOW PH

The UNF upflow NRV Neutralizing Filter features a specialized media that raises the pH of acidic water, effectively neutralizing its corrosive properties. By increasing the pH, it not only protects pipes, plumbing fixtures, and appliances but also enhances the oxidation of iron and manganese, enabling the use of an iron filter. Over time, replenishing the media may be necessary for optimal performance.

Key Features

Economical: Two-tank system that uses one control valve. Simple installation and lower upfront cost.

Upflow Regeneration: Saves salt by preserving the unused portion of the softening bed from unnecessary ion exchange.

Precision Brining: Calculates the exact amount of brine required to regenerate, using up to 30% less salt.

Automatic System Refresh: If no water is used for seven (7) days, the system will perform an automatic refresh to prevent bacteria growth.

Soft Water Brine Tank Refill: Keeps tank & injectors clean.

Soft Water Recharge: If capacity goes below 3%, an automatic 15-minute recharge restores softening until the next regeneration.

Tank Features: Brine tank with safety float, air check and injection molded brine grid to reduce bridging. Moisture wicking neoprene tank jacket included on all pressure tanks.
