Fai Filtri CS-CTT Series Hydraulic Filters are heavy-duty spin-on filters designed to ensure superior contamination control in hydraulic, lubricating, and fuel circuits operating under demanding mobile and industrial conditions. Built for flow rates up to 270 l/min and pressure peaks of 12 bar, they feature reinforced housings, quick-change cartridges, and optional by-pass valves and anti-emptying membranes (CTT version) for optimal reliability and easy maintenance. Each filter element incorporates “A”-type media made of resin-bonded inorganic microfibers, providing absolute filtration from 3 to 25 microns (βx ≥ 200) and high resistance to deformation and contaminant release. These filters deliver stable performance even during cold starts or pressure surges, maintaining efficient contaminant retention and low pressure drop. Compatible with hydraulic oils, lubricants, fuels, glycol water, emulsions, and synthetic fluids, the CS-CTT Series ensures durable, high-efficiency protection for agricultural, construction, and industrial machinery.
