Q4 48 Sq. Ft. DE Filter System with 1.5Hp Variable Speed Pump

Keep your pool water clean and clear with the Black Diamond 48 Sq. Ft. Diatomaceous Earth (D.E.) pool filter system, now paired with the high-efficiency Blue Torrent 1.5 HP Variable Speed (BT-IGV150SP) pool pump. Engineered for residential swimming pools up to 46,000 gallons, this high-performance combo provides professional-grade water clarity while dropping your seasonal power consumption.

Diatomaceous earth is a highly efficient filtration material, filtering water down to 2 to 5 microns. This system easily traps ultra-fine dust, pollen, and algae that pass straight through traditional sand or cartridge filters, delivering a clear pool with fewer chemical corrections. With a high-flow rating of 96 GPM, the tank provides a reliable 8-hour turnover capacity of 46,080 gallons.

The included Blue Torrent 1.5 HP variable speed pump (BT-IGV150SP) is engineered to run at lower, energy-saving speeds for daily filtration tasks. Running a pool pump on low speeds relies on the laws of pump affinity—cutting your motor speed in half drops the electrical power draw by up to 80% to 90% compared to standard single-speed pumps. Because the Black Diamond D.E. filter features a low-resistance internal 2-inch piping system, this combo maximizes your cost savings, keeping your water crystal clear while slashing your monthly utility bills.

Constructed from durable, glass-reinforced thermoplastic, the corrosion-proof filter tank halves are secured by a heavy-duty clamp. This allows fast internal access to the grid assembly without disconnecting any hard plumbing. The system comes complete with a high-flow multiport backwash valve, allowing you to easily flush out trapped dirt and reverse-clean the system with a quick turn of the handle.
