Product Overview

The Pentair Triton® II TR100 Side-Mount Sand Filter (EC-140210) provides durable, high-capacity filtration for large residential swimming pools and demanding water-circulation systems. With 4.91 square feet of filtration area and a maximum flow rate of approximately 98 GPM, the TR100 is designed to deliver consistent water clarity with straightforward maintenance.

Its one-piece, fiberglass-reinforced tank features a UV-resistant surface finish for dependable outdoor performance. The filter’s internal water-distribution system promotes even flow across the sand bed, helping maximize filtration efficiency and prevent channeling.

The TR100 uses standard No. 20-grade silica filter sand and requires only periodic backwashing rather than cartridge removal or replacement. This model features a side-mount configuration and is supplied without a multiport valve unless otherwise specified.

Confirm the following before choosing a valve:

Installation Requirements

Install the filter on a stable, level equipment pad with adequate clearance for plumbing, operation and future service. The system must include a properly sized pump, approved backwash valve and suitable waste-line plumbing.

Installation and servicing should be completed by a qualified pool professional. Always depressurize the circulation system before opening or servicing the filter.
