Onga Fibreglass Sand Filter is the perfect high performance sand filter. It's incredibly simple to operate and maintain, and it's built with long-term reliability in mind. Plus, its highly efficient design provides all the clean, crystal clear water your pool requires year after year. Here's how.
Pool water is routed through the sand-filled pressure vessel. The sand traps particles so small they are undetectable to the naked eye. Over time, dirt accumulates in the spaces between the sand particles, causing the pressure in the vessel to rise. This signals you to “backwash” the filter. Simply reverse the water flow and “knock out” the dirt.
Pool filter operation doesn't come any easier. The multi-port valve puts all filter functions right at your fingertips—just rotate the handle to the desired position and the filter does the rest for sure and simple operation.
