About This Item
The Unicel FG-2413 is a precision-engineered partial replacement DE filter grid for 48 sq. ft. Anthony DE filter systems — specifically the Apollo 4000 and Flowmaster 4000 series. Built with high-grade DE filter fabric and reinforced seaming, this partial grid delivers reliable pressure resistance and long-term durability as an exact aftermarket replacement for Anthony OEM Part Number 17565.
⚠️ IMPORTANT: PARTIAL GRID — NOT A FULL GRID
This is a single (1) partial DE filter grid, used alongside full grids to complete a filter set. A full re-grid of the Anthony Apollo 4000 / Flowmaster 4000 requires seven (7) full grids plus one (1) partial grid (this part). 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
The Anthony Apollo 4000 / Flowmaster 4000 requires 7 full grids + 1 partial grid for a complete re-grid. This listing is for the partial grid only. You will also need — Unicel FG-2417 Replacement DE Filter Grid (Full).
⚠️ IMPORTANT: Apollo 5000 / Flowmaster 5000 Owners — This Grid Will NOT Fit Your Filter
The FG-2413 is a 24" partial grid for 48 sq. ft. (4000 series) systems only. The Anthony Apollo 5000 and Flowmaster 5000 are 60 sq. ft. filters that require 30" grids. Do not order this part for a 5000 series filter.

Pro Tips
Before ordering, confirm which grid position needs replacement — the 13½" partial grid (FG-2413, Anthony 17565) or the 17½" full grid (FG-2417, Anthony 17564). A complete re-grid for the Apollo 4000 / Flowmaster 4000 uses seven (7) full grids and one (1) partial grid. 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 while the tank is open.
