Fai Filtri FCS Series Oil Filters are high-efficiency, inline spin-on filters engineered for hydraulic, lubricating, and fuel circuits requiring dependable contamination control. Designed for flow rates from 10 to 360 l/min and pressures up to 12 bar, these filters minimize pressure losses while maximizing filtration efficiency and contaminant retention. Each unit features new-generation “A” elements made of reinforced inorganic microfibers, ensuring absolute filtration from 3 to 25 microns (βx ≥ 200) with superior resistance to deformation and contaminant release. The compact design enables quick, clean cartridge replacement without special tools, making the FCS ideal for earthmoving, agricultural, and industrial mobile machinery. Multiple versions support both return and suction line installations, with available by-pass valves, visual or electrical clogging indicators, and a wide range of GAS, NPT, SAE, or flanged couplings. Built with galvanized steel, aluminum heads, and Buna-N or Viton® seals, the FCS Series delivers long-term durability, compatibility with hydraulic oils, glycol water, emulsions, and synthetic fluids, and reliable performance even under demanding service conditions.
