Pentair Free Standing Base

The Pentair Free Standing Base (part number R172452) is a specialized structural stabilization platform engineered exclusively to convert and support inline filtration models into independent, self-contained setups. It is designed primarily for the Pentair Rainbow Dynamic Series II and Series III RTL and RCF cartridge filter systems. Injection-molded from a dense, high-impact, and chemically inert polymer compound, this round pedestal base features a contoured central recessed ring and integrated snap-lock or screw fastening channels. Its primary structural role is to cradle the absolute bottom base of the otherwise slender filter housing, expanding its dimensional footprint to create an unyielding foundation directly on the equipment pad or floor.

By low-centering and anchoring the filtration vessel, the base prevents the vertical housing from leaning, tipping, or shifting out of alignment when hit by massive water distribution velocities or sudden pump startup surges. This structural decoupling isolates mechanical movement, ensuring the system safely handles operational loads up to standard limits of 50 PSI without placing stress on the connected inlet/outlet PVC plumbing lines. Engineered to withstand a lifetime of harsh outdoor pad environments or tight indoor spa equipment recesses, its robust plastic framework completely resists material softening, cracking, structural deformation, and corrosive breakdown from chemical splashing or direct contact with pool sanitizers like chlorine and bromine. Due to its rigid, hollow-molded structural geometry, this individual free-standing tank base carries a net product and shipping weight of approximately 0.35 to 0.45 pounds (about 5.6 to 7.2 ounces).
