MANN Oil Separator

Air/oil separators - for your compressed air system

MANN+HUMMEL designs air/oil separators for energy efficiency and low residual oil content. MANN+HUMMEL offers custom-made solutions for oil separation for applications in compressors and vacuum pumps. Efficient separation media ensure the lowest possible residual oil content and high energy efficiency through low pressure loss, which saves users a considerable amount of money. The MANN+HUMMEL product range is the worldwide benchmark for air/oil separation.

 Air-oil separator elements

Low residual oil content extends the service life of fine filters downstream. Minimum pressure losses guarantee energy efficiency and long service life.

 Advantages of MANN+HUMMEL Air-oil separators

• High efficient

• Longer service life and energy efficiency

• Minimum pressure losses.

• Effective, minimum residual oil content of only 1-2 ppm

• Cost saving
• Extends service life of downstream fine filters.

Standard Features

• • Flow rates
    Air Oil Separator Boxes are available for nominal flow rates of 1 m3/min up to 5.5 m3/min (35 to 194 cfm) at an operating pressure of 7 bar (0.7 MPa).

  • Lower Pressure drop

  • Pressure resistance

Air Oil Separators are designed for differential pressures of and upwards 5 bar (0.5 MPa). The housings of the Air Oil Separator Boxes are designed for operating pressures up to a maximum of 20 bar (2 MPa) or a maximum of 14 bar (1.4 MPa)

• • Separation efficiency

The residual oil content of the compressed air at nominal flow rate and 7 bar (0.7 MPa) operating pressure is approximately 1 to 3 mg/m3 (1 to 3 ppm).

• • Service life
    The rise in flow resistance and thus service life primarily depend on the cleanness of the oil and the quality of the air filter. A service life of several thousand hours can be achieved with a well-functioning system.

  • Fitting advice
    Air Oil Separator Boxes are fitted vertically by hand on the firmly installed filter head using a suitable adapter union. 
    MANN+HUMMEL recommends installation in a maintenance-friendly position.

  • Maintenance
    The air oil separator boxes must be replaced if the flow resistance reaches 1 bar (0.1 MPa). The box may only be replaced when the system is depressurised. A commercially available belt wrench is sufficient to remove the box. The box is fitted and tightened manually.

  • Design and function
    This product is suitable for flow from the outside to the inside. It can be used for the entire range of current versions of screw-type and sliding vane compressors.
    The standard wrap elements are particularly insensitive to design variations and achieve optimal results with regard to separation efficiency and service life.
