Pentair 4000 Series DE Filter & Backwash Valve


Pentair 4000 Series DE Filter & Backwash

For water that truly sparkles

Pentair 4000 SERIES D.E. filters are designed for optimal filtration efficiency, easy maintenance, and longer runs between cleaning. Their extraordinary dirt-holding capacity and easy cleanability make them ideal for even large or heavily used pools. 4000 SERIES D.E. filters are engineered to provide high efficiency filtration with a minimum of maintenance. And when occasional maintenance is required, you'll appreciate the safe, user-friendly design of the tank's clamp ring, and the ease with which filter grids can be removed for cleaning.


Additional features include:

Corrosion-resistant 20"-diameter fiberglass tank for strength, durability, and years of service.

Unique SPIRO-MITE* grid design provides high efficiency filtration and longer filter cycles because pool water is always routed through the optimum filtration path.

Exclusive clamp ring design is proven to be one of the safest in the industry. It allows quick and easy access to internal components and leak-free operation.

2" threaded connections for easy installation and maximum flow.

Curved grid assembly provides the most efficient D.E. filtration available.

Durable backwash valve resists corrosion and is unaffected by heat and cold, assuring flawless operation under all conditions.

Thermoplastic backwash rotor seal is specially designed to prevent dirt from entering rotor chamber, resulting in smoother operation.

Ten year tank warranty.
