Fai Filtri GFO, GFS, and GFSO Series Integrated Groups are compact, high-efficiency filtration assemblies engineered for rotary and screw compressors. Each model combines key compressor components - air/oil separator, oil filter, thermostat, and minimum pressure valve - in a single optimized unit that ensures maximum air purity, system reliability, and ease of maintenance. Designed with painted and galvanized steel housings, borosilicate microfiber separators, and cellulose or reinforced polyester filter media, these integrated groups achieve residual oil levels below 1–3 ppm and provide consistent performance at operating pressures up to 16 bar. The GFO models focus on oil filtration and temperature regulation, GFS units integrate air/oil separation and minimum pressure control, while the GFSO combines all functions for complete air management. Built for long service life - with an average operating interval exceeding 2,500 hours - these systems simplify maintenance while minimizing downtime. Ideal for compressors serving food, pharmaceutical, textile, electronic, and mechanical industries, Fai Filtri integrated groups offer reliable, space-saving performance that upholds the highest filtration standards.
