Engine-Shielding Air-Oil Separator

Working Principle of the Air-Oil Separator

Separation follows three stages. Primary separation uses centrifugal force to throw larger oil droplets out of the air stream, cutting the load on the downstream media. Micro-filtration then passes the air through a coalescing media that catches droplets as small as 0.1 μm and merges them into larger drops. Oil reclamation collects the coalesced oil in a gravity chamber and returns it to the lubrication circuit, while clean air or gas exits the separator for downstream use. The three-stage design also keeps pressure loss low at maximum flow, so the compressor system does not lose efficiency when the separator is working at rated capacity. This closed loop keeps oil loss low and air purity stable during continuous operation.

Features of the Engine-Shielding Air-Oil Separator

Separation consistency. The separator removes more than 99.9% of oil droplets and holds oil carryover at 3 ppm or lower, a level suited to applications where trace oil is not acceptable. Heat and pressure tolerance. The corrosion-resistant housing, in aluminum alloy or stainless steel, operates from -10°C to 120°C at pressures up to 10 bar. Low maintenance. The filtration media is replaceable and the collection chamber needs minimal cleaning, which shortens downtime during scheduled service. Sizing flexibility. Port sizes from ½ in. to 4 in. and inline, vertical, or horizontal configurations match different system layouts, with flow rates from 5 to 500 Nm³/h. The separator meets ISO 8573-1 and CE standards, which supports adoption among industrial clients that standardize on international requirements.

Applications of the Air-Oil Separator

Compressed air systems. In rotary screw, reciprocating, and centrifugal compressors, the separator keeps oil out of the air supplied to tools, painting, and packaging processes. Hydraulic systems. It separates air-oil mist from hydraulic fluid, reducing the risk of pump cavitation and keeping cylinder operation smooth in manufacturing machinery. Vacuum pumps. It removes oil vapor in semiconductor laboratories and food processing facilities, where vacuum purity affects product quality. Turbo-machinery. In gas turbines and diesel engines, it separates oil from crankcase air, which helps lower emissions and protect engine components. Chemical industry. Clean gas streams prevent oil-triggered reactions that could compromise chemical synthesis and separation processes. Port sizes from ½ in. to 4 in., flow ratings from 5 to 500 Nm³/h, and inline, vertical, or horizontal mounting cover most compressor, pump, and turbine layouts.

FAQ

How does oil reclamation benefit my operation?

Oil reclamation reduces costs by cutting new oil purchases and waste disposal fees. It also ensures consistent lubrication quality, as reclaimed oil is clean and compatible with your system—extending the life of pumps, rotors, and other components.

Can the separator handle high-temperature air or gas?

Yes, the High-Efficiency Air & Oil Separator is designed to operate in temperatures up to 120°C. Its heat-stable filtration media and corrosion-resistant housing maintain performance even in high-temperature environments like turbo-machinery or industrial ovens.

How often should the filtration media be replaced?

Replacement frequency depends on usage (e.g., air flow volume, initial oil content), but the media typically lasts several months in standard industrial settings. Monitoring pressure drop across the separator (a sign of clogged media) is the best way to determine when replacement is needed—an easy process with the separator’s accessible filter housing.

Is it compatible with different types of lubricating oil?

Yes, the separator works with most industrial oils, including mineral oils, synthetic oils, and biodegradable oils. The filtration media is designed to handle varying viscosities and chemistries, ensuring effective separation regardless of the oil used. For specialized oils, custom media options are available.
