Foundrymax Standard Rectangular 50×75×22mm / 10PPI Silicon Carbide Foam Filter – A Foundry Floor Staple

The 50×75×22mm 10PPI Silicon Carbide Ceramic Foam Filter from Foundrymax represents one of the most commonly specified rectangular sizes in the global casting industry.

With a 10 PPI coarse-pore structure (average pore size ~2.5 mm), this filter delivers excellent molten metal flow rates with minimal back-pressure – a critical requirement for foundries running gray iron, ductile iron, aluminum, or copper alloys in medium‑production volumes. The 22 mm thickness provides robust mechanical strength and outstanding thermal shock resistance up to 1500°C, ensuring the filter remains intact throughout the pouring cycle even under variable temperature conditions.

Key advantages for daily foundry operations:

• Reliably removes coarse slag, dross, and refractory inclusions – directly reducing scrap rates and improving casting yield.

• The rectangular geometry provides broader coverage than a 50×50 square, making it a preferred choice for slightly larger sprue bases or multi‑cavity molds.

• Consistent pore uniformity guarantees predictable filtration performance batch after batch.

• High porosity (>85%) ensures minimal flow restriction, supporting stable mold filling.

Why Foundrymax for this standard size?
As a direct manufacturer, we produce this popular size in large batches, ensuring consistent quality, short lead times, and competitive pricing. We also offer flexibility – same 50×75 footprint available in 15mm, 20mm, or 22mm thickness, and PPI options from 10 to 30. Our technical team can guide you on whether this rectangular format or a 50×50 square better suits your gating design and casting weight.
