Thermoplastic sand filter with multiport valve
The Pentair Aquatic Eco-Systems Arias 4000 Top Mount Filters are the perfect high performance sand filters. They're incredibly simple to operate and maintain, and they're built with long-term reliability in mind. Plus, their highly efficient design provides all the filtration your system requires, year after year.
Sand filters are one of the most popular and cheap ways to filter water, and for good reason. They are simple, effective and require very little attention. Water is routed through a sand-filled pressure vessel. In this method, impurities are extracted from the water using sand to collect and attract the debris as small as 20 to 40 microns. Over time, dirt accumulates in the spaces between the sand particles causing the pressure in the vessel to rise as water finds it harder to pass through. This signals you to "backwash" the filter. Simply reverse the water flow and "knock out" the dirt.
The top-mount, 6-function 11/2" multiport valve of the Arias 4000 puts all filter functions right at your fingertips—just rotate the handle to the desired position and the Arias 4000 does the rest for sure and simple operation. Features a pressure gauge and manual air relief for optimum filtration efficiency. Its internal design ensures that water is exposed to maximum sand surface area for superior filtration performance and efficient backwashing.
