DS100257003 is a high-efficiency air-oil separator filter element specially designed for industrial screw air compressors.It has now been widely adopted as a cross-reference standard part for mainstream industrial filter brands. Its core function is to thoroughly separate and recover micron-sized lubricating oil mist entrained in compressed air at the final stage of air compressor exhaust, so as to supply dry, clean and high-quality compressed air to the downstream gas consumption network.
Structural and Material Characteristics
1. Superfine Glass Fiber Filter Media:
Multi-layer composite microporous glass fiber (such as HV from the US or Binzer filter media from Germany) is adopted. Through interception, gravitational sedimentation and coalescence effects, this multi-layer structure enables tiny oil mist droplets to merge into larger oil droplets as they pass through the filter layer.
2. High-strength Stainless Steel Frame:
Both the inner and outer supporting frames are made of high-strength, corrosion-resistant stainless steel perforated mesh or spiral lock-seam mesh. It can withstand high pressure differentials (generally with a maximum pressure resistance of over 5 bar) and prevent the filter element from being crushed or ruptured under extreme working conditions.
3. Premium Static Conductive and Oil Drainage System:
Static conductive sheets (anti-static gaskets) are fitted on flanges and end caps to prevent system explosions caused by static sparks generated by friction of high-speed airflow. A high-efficiency oil return coalescing layer is designed at the bottom to ensure that the coalesced lubricating oil can flow smoothly back to the oil-gas separator tank through the oil return pipe of the air compressor.
