Filter Aid (Celatom FW-14) (CAS No.: 68855-54-9) is a high-performance functional filter aid primarily composed of natural diatomaceous earth (SiO₂ ≥ 85%), specifically engineered for precision industrial filtration. It appears as a white to off-white powder, featuring a unique porous honeycomb structure, high specific surface area, and exceptional adsorption and particle retention capabilities. Our Celatom FW-14 is manufactured from premium diatomaceous earth sourced from China’s high-quality ore belts (Yunnan and Jilin provinces), undergoing crushing, classification, calcination activation, and precision sieving. Equipped with German-imported sorting equipment, our production bases ensure uniform particle gradation and consistent filtration performance.

Compliant with international industrial filtration standards (GB/T 14936-2016, ASTM D4511-17, ISO 1216:2015), key quality indicators are strictly controlled: bulk density 0.35-0.45 g/cm³, specific surface area 15-25 m²/g, permeability 10-30 Darcy, moisture content ≤ 8%, acid-soluble substances ≤ 2%, and no toxic or harmful impurities (heavy metals Pb/Cd/As ≤ 0.001%). As a leading filter aid supplier in China, we leverage the country’s abundant high-quality diatomaceous earth reserves, mature activation modification technology, and large-scale production capacity to provide efficient, cost-effective filtration solutions for global industries including chemical, food, pharmaceutical, and environmental protection.
