Product Overview

The Pentair Quad D.E. 60 Sq. Ft. Filter | 188592 is designed for high-performance in-ground pool and spa filtration, combining the fine particle capture of diatomaceous earth with a cartridge-style internal design.

With 60 square feet of effective filtration area, the Quad D.E. 60 provides strong dirt-holding capacity and efficient water circulation for residential pool systems. Instead of using traditional vertical D.E. grids, the Quad D.E. series uses four cartridge-style elements that are coated with D.E. powder to create a highly effective filtration surface.

This design offers the clarity associated with D.E. filtration while providing a service-friendly internal configuration for cleaning and inspection.

Specifications

Advanced D.E. Filtration

The Pentair Quad D.E. 60 is designed to provide excellent water clarity by using D.E. powder as the filtration media.

During operation, D.E. coats the internal cartridge-style elements and captures small suspended particles as pool water passes through the filter. This helps remove fine debris that may pass through coarser filtration systems.

The 60 sq. ft. filtration area makes this model a strong option for many residential pools and pool-and-spa combinations.

Cartridge-Style Internal Design

Unlike conventional D.E. filters that rely on traditional grid assemblies, the Quad D.E. system uses four removable cartridge-style elements.

This design provides:

• Large filtration surface area

• High dirt-holding capacity

• Easy inspection of individual elements

• Straightforward cleaning

• Efficient water distribution through the filter

The elements should be inspected regularly for tears, cracking, or other damage that could affect filtration performance.

Maintenance

Proper maintenance is important for consistent filtration and safe operation.

When servicing the filter:

• Turn off the circulation pump

• Relieve all internal pressure

• Open the filter only after confirming pressure is fully released

• Remove and thoroughly clean the internal elements

• Inspect the tank O-ring and clamp assembly

• Reassemble according to Pentair instructions

• Recharge with the correct amount of D.E. media

Never operate a D.E. filter without the proper amount of filtration media.
