Shanghai Greenway supplies air/oil separator boxes.

High quality air/oil separators are crucial for process reliability and energy efficiency in compressors. Lower differential pressure and
residual oil content can add the service life of filter.

Flow rates

Air/oil separator boxes are available for nominal flow rates of 1 m3/min up to 5.5 m3/min at an operating pressure of 7 bar (0.7 MPa).

Pressure drop

The pressure drop at nominal flow rate and at 7 bar (0.7 MPa) operating pressure is approx. 0.25 bar (25 KPa) with a new element.

Pressure resistance

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). The fitted filter elements are suitable for pressure differences greater than 5 bar (0.5 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.

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. We recommend fitting in a position with good access for servicing.

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.
