NOTICE: PrometheanFoam is the exclusive partner with Promethean Metal Foam LLC — the only mass producer of this specific iron‑nickel alloy foam. You won't find our products on Amazon, Walmart, or through distributors. Factory direct only.
Why We Exist
The industrial filtration and thermal management market is dominated by disposable solutions with built‑in obsolescence. We exist to provide permanent alternatives with superior performance.
✓ PROMETHEANFOAM — WE MANUFACTURE
Material Science First: We start with iron‑nickel alloy chemistry, control porosity at the atomic level, and engineer for 10‑year lifespan.
Vertical Manufacturing: From molten metal to finished product in Sheridan, WY. Full control over quality, no outsourced components.
Performance Focus: 95% grease capture (vs 70% for baffle), 85% porosity reduction in aluminum casting, 92.4% PM2.5 efficiency.
Total Cost Ownership: Higher initial cost, but 3‑5 year lifespan eliminates replacement costs. ROI typically 12‑24 months.
Engineering Team: Materials engineers, mechanical engineers, application specialists — all in‑house, all focused on solving industrial problems.
✗ INDUSTRY STANDARD — THEY DISTRIBUTE
Distribution Model: Source from Asia, mark up 300‑500%, sell through Amazon/Walmart/Lowes. Zero control over material quality.
Disposable Design: Products designed for 1‑3 month replacement cycles. Built‑in obsolescence ensures recurring revenue.
Performance Compromise: 70% efficiency is "good enough." No incentive to improve when replacements drive profits.
Hidden Costs: Low sticker price, but 12‑36 replacements over 3 years. Labor costs for maintenance personnel.
Import/Resell: No engineering team, no material science. Just logistics and marketing. Different label on the same Chinese product.
The Material That Powers Everything
Iron‑nickel alloy foam is our core technology platform. The same material architecture drives all our applications — just different pore densities and surface treatments.
CHEMISTRY
Iron-Nickel Alloy (Fe-Ni)
80‑20% Fe‑Ni ratio optimized for corrosion resistance in commercial kitchens, aluminum casting, and HVAC environments. Melting point 2600°F+ ensures stability in extreme conditions.
POROSITY ENGINEERING
85‑90% Engineered Porosity
Not random — consistent 3D interconnected pore structure. 8‑12× surface area vs traditional filters enables 95% grease capture and 92.4% PM2.5 efficiency.
THERMAL CONDUCTIVITY
50‑70 W/m·K (20× Ceramic)
High thermal conductivity enables passive dehumidification (0W electricity) in HVAC and reduces thermal gradients in aluminum casting (85% porosity reduction).
MECHANICAL STRENGTH
15‑25 MPa Compressive
Withstands metalostatic pressure in aluminum casting, grease loading in commercial kitchens, and vibration loads in semiconductor fabs without deformation.

Frequently Asked Questions
Common questions about our company structure, manufacturing, and business model.
We are the exclusive partner with Promethean Metal Foam LLC — the only mass producer of this specific iron‑nickel alloy foam. We manufacture everything in Sheridan, Wyoming. We are not a distributor, reseller, or importer. You won't find our products on Amazon, Walmart, or through third‑party distributors.
Distributor markup (typically 300‑500%) destroys our value proposition. Our filters cost 2‑3× more upfront but last 3‑5 years vs 1‑3 months for disposables. Adding distributor margins makes the upfront cost prohibitive. Factory direct ensures customers get the true total‑cost‑of‑ownership advantage.
Exclusive partnership. Promethean Metal Foam LLC developed the iron‑nickel alloy foam production technology. We are their only manufacturing and sales partner. This arrangement ensures material consistency, quality control, and technical support alignment across all customer interactions.
Both. A single‑location restaurant replacing one filter is as important to us as a Fortune 500 aluminum foundry ordering container‑load quantities. Our manufacturing scale allows us to serve both without compromise — no minimum order quantity for sample kits and small replacement orders.
Four core industries: 1) Commercial kitchens (restaurants, hotels, casinos) — grease filtration; 2) HVAC contractors — humidity control and PM2.5 filtration; 3) Aluminum foundries — casting defect reduction; 4) Semiconductor fabs — vibration isolation. All use the same iron‑nickel alloy foam with different pore densities and configurations.
