Description
The Atlas Copco Air/Oil Separator 2901085800 (also referenced as 1613984001 and 1613984000) is a premium OEM-quality separation element specifically engineered for Atlas Copco GA55, GA75, GA90, and GA90C series rotary screw compressors. This separator efficiently removes oil mist and aerosols from compressed air while maintaining optimal compressor lubrication and system reliability. Featuring advanced coalescing filtration media constructed from high-quality materials, the 2901085800 effectively captures fine oil particles and directs recovered oil back into the compressor’s air end lubrication circuit, ensuring clean, dry compressed air output and continuous efficient operation.
Built with precision engineering and robust construction, this separator is designed to withstand the extreme pressures and temperatures of demanding industrial compressed air applications. The rigid structure maintains even pressure differentials and resists collapse under high-pressure operation, protecting against premature failures and system shutdowns. Compatible with Atlas Copco GA55, GA75, GA90, and GA90C mid-capacity compressors, the 2901085800 delivers consistent, reliable separation performance across extended service intervals. With high-performance filtration efficiency achieving oil content reduction to 1-3 ppm, this separator provides superior protection for downstream equipment while reducing maintenance requirements, operational costs, and environmental impact. The separator’s proven reliability makes it an ideal choice for industrial facilities requiring consistent compressed air purity.
