Air/Oil Separator Element DB2023

The DB2023 industrial air compressor oil-gas separator element is an in-depth coalescing filter cartridge designed specifically for oil-injected screw air compressors. Its core function is to efficiently separate and recover lubricating oil mist from compressed air, ensuring high-quality clean compressed air with low oil content at the output, while reducing lubricating oil consumption.

Core Product Advantages and Design Features

• High-precision deep coalescing filtration.

Adopting multi-layer superfine glass fiber composite filter media, it can coalesce micron-sized oil mist particles smaller than 0.1 μm into large oil droplets that settle to the bottom of the filter element. Under normal working conditions, the residual oil content of the outlet compressed air can be stably controlled within 2–3 ppm.

• Low initial pressure difference and energy-saving performance.

Featuring a rational pleated design and multi-layer gradient pore structure, the initial pressure difference does not exceed 0.25 bar at the rated flow of approximately 780 m³/h (13 m³/min), effectively reducing the operating power consumption of the air compressor.

• High-strength pressure-resistant structure.

High-strength anti-corrosion galvanized perforated steel support frames are equipped on both the inner and outer sides, which can withstand instantaneous pressure shocks during compressor start-stop operations or under extreme working conditions to prevent deformation or collapse of the filter element.

• Original-equipment-level static-conductive safety design.

Oil-resistant sealing gaskets come as standard on the upper and lower flange faces, with conductive metal pins (copper pins) embedded inside the gaskets. These safely conduct static electricity generated when oil and gas pass through the filter media at high speed to the oil-gas tank shell, eliminating the risk of static-induced ignition and explosion in the oil-gas mixed environment.

Typical Application Scenarios and Compatible Models

• Compatible host types.

Mainly applied to oil-injected screw air compressors with built-in oil separation structure and a rated displacement of 12–14 m³/min (approximately 75 kW power range).

• Wide compatibility with mainstream brands.

Featuring internationally standard dimensions (outer diameter 275 mm × height 400 mm, flange outer diameter 328 mm), it can directly replace original and aftermarket parts of the same specification from brands including Boge, Fini, MANN-FILTER (4900051441 / LE 35 002 x), Keltec, etc.

• Applicable industries.

Widely used in scenarios with strict requirements on the oil content of compressed air, such as machinery manufacturing, automotive coating, textile and chemical fiber, food packaging, electronics and semiconductors, and general industrial pneumatic systems.
