All compressors produce a condensate with hazardous waste of oil and dirt.
This condensate must be treated with care. The product is polluted and must not be led out in the sewage or on the floor. The contaminated water should be collected in an Oil and Water separator. The separator will separate the condensate into water and oil through a secure process that ensures that the contaminated waste is treated according to government control. The water can now be lead into the sewage and the oil must be handed over to a chemical waste site.
When you treat the contaminated water you also prevent your equipment from corrosion in pipes. The Oil and Water separator exist in 2 versions. One is built into the compressor and works as an integrated unit. The other one is a stand-alone unit that can be placed anywhere suitable.
