- SMD Series deliver high quality D.E. filtration in a simple, one-piece module design that's easier to clean than grid designs. The unique balanced-flow tank design maximizes the use of the module's surface area to trap more dirt and reduce the frequency of cleaning.

Water flows very efficiently through System:3 Modular D.E. Filters - SMD Series allowing the use of smaller pumps or lower pump speeds to minimize energy use. And when consumers rinse cartridges rather than backwash, they can significantly reduce water use, too.

• Typical Installations - Inground pools, inground hot tubs, and water features
• Quality Construction - Durable two-piece tank housing constructed of Dura-Glas, Sta-Rite's industry leading glass-reinforced composite resin
• Safe - Posi-Lok clamps provide safe, easy access to tank internals Modular Filter Tanks - Allows for quick change of filter medias without changing the tank
• Dual Drain Plugs - Side plug assembly includes 1-1/2" NPT port for direct discharge plumbing
• Sleek Looks - Contemporary style and matte black finish looks attractive in any pool setting
