Nelsen 13x54 Filter Unit

Sized for larger households and higher demand, the Nelsen 13x54 Filter Unit delivers automatic backwash-only filtration in a robust, easy-to-maintain package. Also referenced as part CAF-13, this whole-house system combines a generous 13" x 54" mineral tank with a dependable Nelsen control valve to give homeowners clean, well-conditioned water with minimal day-to-day attention. It is an ideal foundation for households that have outgrown smaller filters or simply want extra capacity.

• 13" x 54" black polyglass mineral tank with strong corrosion resistance
• Nelsen C-Series EE 1" 3-cycle backwash filter valve for automatic cleaning
• Bypass valve included to simplify service and maintenance
• Basket distributor and gravel bed for uniform flow and media retention
• Approximate weight of 95 lbs per unit
• Filter media and plumbing connections sold separately

The three-cycle backwash valve automatically reverses water flow on a set schedule, lifting and rinsing away accumulated sediment so the media bed stays effective over time. This self-cleaning action is what makes a backwashing filter so practical: rather than swapping cartridges every few months, the system maintains itself, and the only major upkeep is periodic media replacement based on your water chemistry and usage patterns. The result is consistent performance with very little hands-on effort.

With media chosen separately, the Nelsen 13x54 can be configured for sediment removal, chlorine and odor reduction with carbon, or other targeted treatment goals. The larger tank diameter and taller profile provide added contact time and capacity, supporting homes with greater water demand. Add the plumbing connections suited to your home, select your media, and this filter unit becomes a high-capacity centerpiece of a whole-house water treatment setup. It is an excellent choice for installers building custom systems and for homeowners who want lasting, hands-off filtration from a well-regarded water treatment brand.

Proper installation and a drain line of adequate size will ensure backwash cycles run effectively, carrying flushed particulate away without restriction. With the right media selected for your water test results, this Nelsen platform delivers years of dependable service while keeping operating costs low and water quality high throughout the home. As a trusted Nelsen system paired with proven Nelsen control hardware, it brings professional-grade filtration within reach of homeowners and installers alike.
