Pentair 30" Triton® II Heavy-Duty Fiberglass Side Mount Sand Filter TR100HD Black

Pentair Sand Dollar® 22" Top Mount Sand Filter (EC-145322)

The Pentair Sand Dollar® 22-inch Top Mount Sand Filter (Product #: EC-145322 / SD60) is a highly efficient, single-vessel water filtration system optimized for online retail distribution and engineered to provide exceptional water clarity for small-to-medium residential inground or above-ground swimming pools. The filter vessel is blow-molded as a single, seamless unibody from a premium, UV-resistant thermoplastic composite resin that guarantees total immunity to rust, scale, and long-term chemical degradation under intensive outdoor weather exposure. This package is outfitted with a heavy-duty, clamp-style 1.5-inch six-position top-mount multiport valve (MPV) with an ergonomic lever handle, allowing pool owners to effortlessly switch between filter, backwash, rinse, waste, closed, and recirculate functions. Internally, the SD60 utilizes an advanced self-cleaning lateral matrix and a specialized underdrain grid system that forces water uniformly across its 2.3 square feet of effective filtration area, comfortably supporting a maximum design flow rate of up to 60 gallons per minute (GPM) at a maximum continuous working pressure of 40 PSI. This hydraulically optimized internal flow profile prevents water channeling, ensuring maximum debris retention and extended filtration cycles to lower general energy use when paired with modern variable speed pumps. Routine maintenance and seasonal shutdown procedures are highly streamlined by a convenient combination sand-and-water drain plug at the base of the tank for rapid winterization, alongside a top-mounted pressure gauge and a manual air relief system. The dry product weight of the Pentair Sand Dollar EC-145322 filter body complete with its top-mount multiport valve is approximately 44 pounds (noting that full operational deployment requires an initial media charge of 250 pounds of standard pool silica sand), standing as a lightweight, exceptionally rugged, and low-maintenance centerpiece for dependable pool water management pads.
