About This Item
The Unicel FG-3011 is a single replacement DE filter grid engineered for the Sta-Rite System 3 Model S8D110 and compatible legacy Sta-Rite Swimquip DE filter systems that use OEM grid part number 23900-0032. Measuring 11" wide × 18" long with a center port configuration, this grid replaces OEM part number 23900-0032 and is one of four different grid sizes that make up the S8D110's 10-grid inner DE element assembly.
⚠️ IMPORTANT: CHECK BEFORE YOU BUY
This product is a single (1) replacement DE filter grid — it is NOT a complete set. A full filter service requires multiple grids. Please verify the quantity and type (full or partial) needed for your specific filter model before ordering.
⚠️ IMPORTANT: S8D110 Multi-Grid System — 4 Different Grid Sizes Required
The Sta-Rite System 3 S8D110 uses a 10-grid inner DE element assembly requiring four different grid sizes. This listing (FG-3011) covers only 2 of the 10 grids. You will also need FG-3016 (qty 1), FG-3019 (qty 4), and FG-3916 (qty 3) for a complete inner element service. See the grid breakdown table below. For the complete 10-grid set in one purchase, see Unicel FS-3053 (if available).

S8D110 Inner DE Element — Grid Assembly Breakdown
The Sta-Rite System 3 S8D110 is a hybrid filter combining an inner DE grid element with a large outer pleated cartridge — it is not a standard all-grid DE filter. The 10-grid inner DE element assembly requires all four grid sizes listed below for a complete service:

Pro Tips
- Verify your port type before ordering. The S8D110 uses both center port and offset port grids — FG-3011 is center port only. Installing the wrong port type will prevent proper manifold seating and cause leaks or poor performance.
- Hybrid filter reminder. The S8D110 combines an inner DE grid element with a large outer pleated cartridge. When servicing the filter, inspect both the inner DE grids and the outer cartridge — neglecting either will reduce overall filtration performance.
- Confirm your grid dimensions. Verify your existing grid measures 11" wide × 18" long with a center port before ordering. Minor dimensional mismatches can prevent proper fit within the manifold assembly.
- Safety first — always release pressure before opening. Turn off the pump and release all pressure from the filter tank via the air relief valve before opening the tank to inspect or replace grids.
