Nelsen 14" x 65" Filter Unit

The Nelsen 14" x 65" Filter Unit from Water Softener Plus is a commercial-grade backwashing filter system built around the advanced Nelsen WS1.5EE 1-1/2" control valve. Designed for commercial and industrial applications, this system pairs a robust mineral tank with intelligent, fully programmable control to handle demanding filtration duties day in and day out.

Powerful Nelsen Control

The WS1.5EE valve is engineered for high-flow service, delivering a service flow rate of 60 gpm and backwash at 50 gpm, with lead-free brass construction for durability and potable-water compliance. Its solid-state microprocessor offers easy front-panel programming with six fully adjustable cycles, including controlled backwash, down-flow brining and slow rinse, a second backwash, fast rinse, refill, and down-flow service. An optional double backwash feature provides optimum regeneration, cleaning ability, and efficiency for applications that need it.

The front-panel display keeps operators fully informed, showing time of day, days until next regeneration, volume remaining, current flow rate, and total volume used via the built-in totalizer. This level of visibility makes it easy to monitor performance and plan maintenance. Regeneration can be configured as meter immediate, meter delayed, or time-clock delayed to suit the application's usage pattern, and post-treated water is used for the regenerant refill.
