Hayward ProSeries Plus Sand Filter S311SX

The ProSeries Plus Side-Mount Sand Filter incorporates the most advanced maintenance features that satisfies the requirements of the most demanding installations such as, in-ground swimming pools and spas with in-floor cleaning systems, fountains and solar heating systems. These heavy duty systems can weigh on filters and create stress and damage over time, however this filter can outlast all the wear and tear. Its spherical tank design evenly distributes the high pressure associated with the fore-mentioned applications. The filter is quality assured with the greatest strength and a well evolved life span because of its corrosion proof, polymeric material and its progressive design.

This Side-Mount Sand Filter can withstand the most rigorous applications and is effective throughout years of use, never declining in performance. The up-keep and maintenance is simple because of the durable, flanged inspection cover which provides quick access on the top side of the filter.
