Precision Filtration for Fiber Optic Cable Manufacturing

Fiber optic cable manufacturing requires absolute gas purity to prevent defects and ensure consistent performance. Mott’s GSP1500 GasShield® Penta® Filters deliver 9-log particle retention down to 0.0015 µm, outperforming polymer alternatives while operating at pressures up to 650 psig and temperatures up to 460 °C. Built from 316L stainless steel with Penta® Nickel media, these filters are the industry choice for reliability and long-term performance in optical fiber production.
