{"product_id":"unicel-pg-1905","title":"Unicel PG-1905 Replacement Filter for Hayward DEX6000DC","description":"\u003cdiv class=\"pz-pdp\"\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cp\u003eThe Unicel PG-1905 is a precision-molded DE grid element engineered as a direct OEM-equivalent replacement for the Hayward DEX6000DC grid assembly, supplied as a complete grid for ProGrid-class diatomaceous earth filter systems. Grid construction consists of polyester filtration fabric bonded to a high-impact thermoplastic frame, with reinforced corner geometry and a centralized manifold port for full-flow communication with the collector hub. The grid is rated for standard DE filter operating conditions: continuous service to 50 PSI, maximum water temperature 104°F, and compatible with 1.0–2.0 lb DE loading per 10 sq ft of total grid surface area in the assembled grid set. Fabric weave specification supports nominal 3–5 micron filtration efficiency under properly precoated operating conditions, producing filtrate clarity superior to cartridge or sand media at equivalent flow rates.\u003c\/p\u003e\n\u003cp\u003eService interval: backwash when ΔP rises 5–8 PSI above clean-filter operating baseline, followed by DE recharge at the manufacturer-specified loading rate. Full disassembly, grid inspection, and manifold O-ring evaluation are recommended annually or at season open; replace any grid exhibiting fabric tears exceeding 1 inch, delamination from the frame, frame cracking, or visible channeling. Chemical compatibility: polyester fabric tolerates continuous operation at ≤ 10 ppm free available chlorine and is compatible with muriatic acid wash at 1:20 dilution (maximum 20-minute exposure) for calcium scale and mineral deposit removal; enzyme cleaners are compatible without restriction for oil and organic loading. Following grid replacement, verify manifold seating, confirm air bleed-off, and document post-installation clean-filter pressure as the new ΔP baseline for subsequent service cycles. Standard Unicel 90-day manufacturer defect warranty applies through authorized distribution.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cp\u003eYour order includes the selected quantity of DE filter grid sets.
