Sand Filters are manufactured with high grade fiberglass and resins utilizing the latest engineering techniques ensuring high quality and superior strength for long life and durability. Sand Filters feature improved water circulation through a balanced layout of internal lateral nozzles positioned internally at the base of the filter tank. This enables water to be distributed evenly throughout the entire filter bed trapping debris and contaminants before pure fresh water returns via the multiport valve to the pool. Just as sand is utilized to cleanse our oceans and rivers you too can enjoy the benefits of a sand filtered swimming pool.
