Unicel PG-1906 Partial DE Filter Grid | 36″ | 72 Sq. Ft. Systems

Description

The Unicel PG-1906 is a single partial replacement DE filter grid engineered for 72 square foot diatomaceous earth filter systems from Hayward, Pentair (American Products), and Pentair (Pac Fab). At 36 inches in length with a precision open-slot collar (2 notches), this partial grid is built to exact dimensional tolerances for a secure manifold fit, reliable pressure resistance, and extended service life in demanding residential pool applications.

⚠️ 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 of a 72 sq. ft. filter requires 7 full grids + 1 partial grid (this item). You will also need companion full grid — Unicel FG-1006 Replacement DE Filter Grid.

Prefer to buy everything at once? The Unicel FS-2006 Complete DE Filter Grid Set includes all 8 grids needed for one full filter service.

(This is not an exhaustive list.)

Pro Tip: 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. Inspect the tank o-ring and manifold assembly during re-grid service. When measuring your existing partial grid, measure the plastic frame end-to-end and exclude the top collar — compare to the 36″ length and 9″ width of the PG-1906 to confirm the correct fit before ordering.
