Description
The Unicel PG-1902 is a single partial DE filter grid engineered for 24 square foot DE filter systems from Hayward, Pentair (American Products & Pac Fab), and Astral. At 12 inches in length, this precision-built partial grid completes the 8-grid configuration required for a full filter service — working alongside 7 Unicel FG-1002 full grids to restore peak filtration performance and pressure efficiency to your DE system.
⚠️ IMPORTANT: PARTIAL GRID — NOT A FULL GRID
This is a single partial DE filter grid, used alongside full grids to complete a filter set. Verify your filter model’s grid configuration before ordering — partial grids are NOT interchangeable with full grids.
⚠️ IMPORTANT: Full Grids Also Required — This is the Partial Grid Only
A complete re-grid service for these 24 sq. ft. DE filter systems requires 7 full grids + 1 partial grid. You will also need — Unicel FG-1002 Replacement DE Filter Grid.

Pro Tips
- Always turn off the pump and release all pressure from the filter tank via the air relief valve before opening the tank to replace grids.
- Measure your existing partial grid (collar excluded) to confirm the 12″ length matches before ordering.
- Inspect the collar’s open slot and notch alignment against your manifold before installation — the 2-notch configuration must seat properly for correct water distribution.
- Take advantage of a full re-grid service to inspect the tank o-ring and manifold assembly for wear or cracking while the filter is open.
- Use your filter model’s OEM part number above to cross-verify compatibility before purchasing.
