Our Air Oil Separators work according to the "principle of coalescence“. Micro-glass-fiber layers separate drops of oil from the compressed air and return them in large drops to the oil circuit of the compressor. The separation process is effective right down to the submicron range. This ensures that oil consumption in the compressors and oil entrainment into the compressed air networks are kept to a minimum. Vapor oil particles are not separated. Our Air Oil Separators can be used with all types of standard compressor lubricating oils, irrespective of whether they are mineral-based, synthetic or partially synthetic products.
