Nelsen 16" x 65" Filter Unit

Step up to greater capacity with the Nelsen 16" x 65" Filter Unit from Water Softener Plus, a commercial backwashing filtration system controlled by the high-performance Nelsen WS1.5EE 1-1/2" valve. The larger 16" tank holds more media than the 14" model, making this unit well suited to commercial and industrial sites with higher treatment demands and larger daily volumes.

The Nelsen WS1.5EE control valve is the brains of the system, featuring a solid-state microprocessor with easy-access front-panel settings and six fully adjustable cycles. Those cycles deliver controlled backwash, down-flow brining and slow rinse, a second backwash, fast rinse, refill, and down-flow service, giving operators precise control over the regeneration process to suit their specific media and conditions. An optional double backwash feature enhances regeneration, cleaning, and efficiency still further for the most demanding applications.
