The OUK series liquid separator is a multi-stage oil mist separator designed to remove oil mist aerosols from process air in machining equipment using coolants and lubricants. Thanks to efficient filtration, emissions remain below 1 mg/m³, complying with the oil mist aerosol limit values of the Danish Environmental Protection Agency Regulation

No. 682 (2014). The separator is available in 10 combinations across models OUK 4000, 8000, 12000 and 16000.
