50x30x22(mm) 10ppi 20ppi Grey Silicon Carbide Filters in CI and SGI Castings

Foundrymax – Narrow Rectangular 50×30×22mm / 10PPI & 20PPI Grey Silicon Carbide Filters

• Material: Silicon Carbide (SiC), grey color, max working temp 1500°C

• Pore Density Options: 10 PPI (for ductile iron/SGI) | 20 PPI (for gray iron/CI)

• Size: 50 × 30 × 22 mm (narrow rectangular – only 30mm wide)

• Features: 3D reticulated structure, porosity 80–87%, excellent thermal shock resistance (1100°C to room temp, 6 cycles); effectively removes slag, dross, and sand inclusions

• Applications: Gray iron (CI) and ductile iron / spheroidal graphite iron (SGI) castings – ideal for narrow gating systems, small to medium castings

• Filter Capacity (10PPI): 60 kg grey iron / 30 kg ductile iron; Flow Rate (10PPI): 4 kg/s (grey) / 3 kg/s (ductile)

• Filter Capacity (20PPI): 47 kg grey iron; Flow Rate (20PPI): 3 kg/s (grey)

• Manufacturer Advantage: Foundrymax – in-house production, dual PPI options for the same footprint, standard sizes in stock, factory pricing

Foundrymax presents the 50×30×22mm Grey Silicon Carbide (SiC) Ceramic Foam Filter – a narrow rectangular filter engineered specifically for foundries running gray iron (CI) and ductile iron / spheroidal graphite iron (SGI) castings through restricted gating systems or narrow runners. With a width of just 30mm, this format is one of the slimmest rectangular filters available, making it the ideal choice when gating space is limited but filtration cannot be compromised.
