Introduction to Oil Separation Filter Element
screw air-oil separator for compressor.The oil separation filter element is a critical filtration component in compressed air systems, designed to separate oil from the air-oil mixture. It is predominantly installed in oil-injected screw compressors and vacuum pumps, ensuring that the discharged compressed air contains minimal residual oil content.screw air-oil separator for compressor.
The oil separation filter element is a core precision filtration component used in oil-injected screw compressors and vacuum pump systems to achieve effective oil‑air separation. Its primary function is to efficiently intercept and recover entrained lubricating oil from compressed air, reducing the outlet oil content to an extremely low level, thereby protecting downstream equipment and meeting process requirements for air purity.screw compressor oil separator.
product feature
Made of multi-layer ultra-fine glass fiber or synthetic fiber media, offering high filtration precision and low flow resistance.
Stable separation performance, with outlet oil content typically controlled below 3 ppm.
Resistant to high temperatures and corrosion, suitable for continuous long-term operation.
Compact structure with low pressure drop and energy-efficient performance.
Equipped with oil return or drain designs for convenient maintenance and replacement.
working principle
As compressed air containing lubricating oil droplets enters the filter element, the airflow first passes through the outer coarser fiber layer. Larger oil droplets collide with the fiber surfaces due to inertia, becoming captured and coalescing into larger drops. The airflow then moves through the intermediate layer, where medium‑sized droplets are directly intercepted by the fibers as the streamlines are blocked. Finally, in the inner ultra‑fine fiber zone, microscopic oil droplets are captured through Brownian diffusion, adhering to the fiber surfaces and gradually coalescing.screw compressor oil separator.

FAQ
1. Q: Can the oil separation filter element be cleaned and reused?
A: No. This is a disposable product. Cleaning damages the fiber structure and destroys filtration performance. A new element must be installed to guarantee proper operation.
2. Q: What is the proper way to store spare filter elements?
A: Keep them in a dry, cool place away from direct sunlight. Maintain original sealed packaging to prevent moisture and dust contamination. Storage time should not exceed two years.
3. Q: How does your product perform compared to genuine OEM parts?
A: Our elements use equivalent or higher‑grade imported media and are manufactured to strict international standards. We achieve comparable separation efficiency and pressure drop performance while offering a more competitive price.
4. Q: Do you offer discounts for bulk orders? What is the lead time?
A: Yes, volume discounts are available based on order quantity. Standard models are readily stocked and ship within 3–5 working days. Customized models typically require 15–20 working days for delivery.
