The Pentair Triton II TR100 Side Mount Sand Filter EC-140210 is a premium in-ground pool sand filter built for dependable water clarity, long service life, and low-maintenance operation. With a 30-inch fiberglass-reinforced tank, 4.91 sq. ft. filtration area, and 600 lb sand capacity, the TR100 is ideal for large residential pools and higher-demand pool systems.
The Triton II series has long been recognized as an industry-standard sand filter line. Its one-piece fiberglass tank is made using Pentair’s GlasLok™ process, creating a UV-resistant and corrosion-resistant exterior built to handle outdoor equipment pad conditions. The internal flow design helps ensure water is distributed evenly through the sand bed for clear, consistent filtration and longer runs between backwashing. Pentair also lists the Triton II series with threaded bulkhead connectors, a heavy-duty closure with built-in pressure relief, and a design focused on easier inspection and service.
