Air Oil Separator DB2089

DB 2089 Industrial Oil-Gas Separator is a built-in deep folded coalescing filter element specially designed for high-power screw and rotary vane air compressors. It is used to efficiently separate and recover lubricating oil from compressed air.

Core Technical Advantages

• High-precision borosilicate microglass fiber filter media.

Multi-layer composite borosilicate micro glass fibre is adopted as the coalescing medium, delivering extremely high interception and coalescence efficiency for oil mist particles larger than 3 µm.

• Deep-pleated structure.

Compared with conventional wound filter elements, the deep-pleating process provides a larger effective filtration area within a limited dimension (outer diameter 299 mm × height 500 mm), achieving an ultra-low initial pressure drop of 0.15 – 0.25 bar and reducing the energy consumption of air compressor loading.

• High-strength pressure-resistant and temperature-resistant design.

Anti-corrosion high-strength metal support screens are fitted on both inner and outer sides. It can withstand a maximum collapse differential pressure of 5 bar. The end caps are bonded with high-temperature resistant two-component epoxy resin, enabling stable continuous operation at 120 °C and compatibility with mineral oils, semi-synthetic oils and fully synthetic compressor oils.

• Anti-static safety protection.

Static-conductive metal pins/copper sheets are equipped on the flange gasket, which can directly conduct static electricity generated when oil and gas pass through the filter media at high speed to the grounded metal oil-gas tank, eliminating the risk of static ignition and explosion of oil-gas mixtures inside the tank.

Applicable Scenarios and Maintenance Recommendations

• Compatible Models.

Direct replacement for Mann-Filter models 49 305 52 131, 49 305 52 111, 98262/174, etc. Widely used for routine maintenance of general screw air compressors from Atlas Copco, Ingersoll Rand, Sullair, Bolaite, Fidelity and other brands.

• Recommended Replacement Interval.

Under normal operating conditions, replacement is recommended every 3000 – 4000 operating hours. If the oil separator pressure differential shown on the air compressor control panel exceeds 0.8 – 1.0 bar, or the oil content in exhaust rises significantly, shut down the machine and replace it in advance.
