Hydromatic AC-DE 50 Above-Ground D.E. Pool Filter System with 1.5 HP Pump

Keep your backyard swimming pool clean and clear with the Hydromatic AC-DE 50 Above-Ground D.E. Pool Filter System with 1.5 HP Pump. This upgraded equipment package matches a high-efficiency Diatomaceous Earth (D.E.) filter tank with an ultra-powerful, high-velocity 1.5 horsepower above-ground pool pump. Sized appropriately for standard above-ground pools up to 10,000 gallons, this integrated combo system delivers maximum circulation, aggressive water turnover, and practical filtration performance.

This system uses Diatomaceous Earth (D.E.) to trap fine dirt, dust, and microscopic debris down to 1–5 microns. It is designed to keep your pool maintenance simple by eliminating traditional backwashing. When it is time to clean out the trapped dirt, you just isolate the water lines and rinse the inner grid assembly off with a standard garden hose. Both the heavy-duty 1.5 HP pump and the weather-resistant filter tank sit aligned on a rugged composite equipment base that keeps your plumbing stable, isolates vibration, and prevents shifting on backyard surfaces.
