Foundrymax Round 90mm Dia × 22mm Thick / 10PPI Silicon Carbide Ceramic Foam Filter

Foundrymax offers the 90mm diameter × 22mm thickness Round Silicon Carbide (SiC) Ceramic Foam Filter, a disc filter suitable for a wide range of molten metal filtration applications across ferrous and non‑ferrous foundries. The 90mm round format provides a larger cross‑section than standard 50mm and 70mm discs, making it a practical choice for larger sprue bases, pouring basins, and runner systems where higher melt throughput is required.

The three‑dimensional reticulated network ensures uniform pore distribution across the entire disc, delivering consistent filtration efficiency pour after pour. By removing non‑metallic inclusions early in the filling process, this filter helps improve casting density, reduce scrap rates, and enhance surface finish on finished components.

Why Foundrymax for this round filter?
As a direct manufacturer, we produce this 90mm diameter size in regular batches, ensuring consistent quality and dimensional accuracy. We offer the same diameter in alternative thicknesses (15mm, 22mm) and different PPI values (10, 15, 20, 30, 40) upon request, allowing you to tailor the filter to your specific casting weight and gating design. Our technical team can advise on the optimal thickness and pore density for your alloy and production conditions.
