Low-Resistance Porous Filter
A porous material with a highly ordered, straight-through micro-pore structure, designed for server and data-center ventilation. Its ultra-low resistance replaces conventional high-resistance filter media, directly cutting fan power and PUE while extending service intervals.
AeroClay™ · ordered straight-through pores · density ≤0.1 g/cm³
Ultra-Low Resistance
The ordered straight-through pores bring initial resistance down to ≤80 Pa (32 L/min) — far below conventional media. Lower resistance means lower fan power and PUE, less noise and more thermal headroom: dust protection no longer drags down cooling.
Heat-Resistant · Flame-Retardant
Continuous operating temperature −40 ~ +250 °C, flame rating UL94-V0 (the highest class). It meets data-center fire-safety and high-temperature requirements without adding fire risk.
High Porosity · Ordered Pores
An ordered through-pore structure with ≥90% porosity and 5–50 µm pores captures particles by depth filtration rather than surface sieving — giving high dust-holding potential and longer change intervals, at a density of just ≤0.1 g/cm³.

We are glad to provide samples for your in-house lab to evaluate dust performance under ASHRAE 52.2 at real face velocities. Data from your standard and your equipment makes the most credible basis for selection:
Gravimetric Efficiency
Mass-based capture for ≥5 µm particles (Arizona Road Dust / ISO coarse) — matching the dust spectrum servers actually face.
Initial Resistance
Clean-state pressure drop at your chosen face velocity, directly translating to fan power, PUE and noise.
Dust-Holding Capacity
Resistance–loading curve and final-resistance criterion, giving real-world life and change intervals.
The environments you serve demand both maximum cooling and reliable dust protection. Conventional dust screens eat into thermal headroom with their high resistance, whereas this material’s low resistance does not compete with cooling for pressure, and its heat-resistant, flame-retardant nature adds no fire risk — offering a way to have both, for a more reliable and efficient cooling solution.
Samples for Joint Validation
We provide samples and baseline data, and look forward to joint testing — validating this “low-resistance + heat-resistant + high-dust-holding” solution in different application scenarios.
