Air/Oil Separator Element LE57003x

LE57003x is an industrial high-quality Air/Oil Separator Element, designed for after-sales maintenance and original equipment matching of medium and large oil-injected screw air compressors.

Applicable Scenarios 

This model is generally suitable for medium and large general-purpose screw air compressors with a power of approximately 55kW to 110kW (such as Ingersoll Rand, Ceccato, CompAir and other brands)

Core Selling Points

1. Extremely low residual oil in exhaust (no oil carry-over, protects downstream equipment)

• Selling point: Residual oil content of compressed air after separation ≤ 1–3 mg/m³ (ppm).

• Customer value: Prevents oil carry-over of the air compressor and greatly cuts the daily consumption of costly lubricating oil. Meanwhile, it guarantees sufficiently clean discharged compressed air, protecting downstream pipelines, pneumatic components and sophisticated post-treatment equipment (such as refrigerated dryers, adsorption dryers and precision filters) from oil contamination.

2. Extremely low operating pressure drop (high energy efficiency, lower power bills)

• Selling point: The initial saturated pressure drop under standard working conditions is generally ≤ 0.2 bar [1], and the pressure drop rises extremely slowly throughout the service life.

• Customer value: Over 7% of an air compressor’s energy consumption is typically used to overcome filter element resistance. A low pressure drop means the motor does not need extra output power. It can save factories substantial electricity costs during long-term continuous operation and meet energy conservation and emission reduction standards.

3. High-efficiency submicron coalescence technology (thorough filtration)

• Selling point: Adopts proprietary multi-layer glass fiber composite filter media, with a separation efficiency of > 99.9% for the most difficult-to-capture 0.3-micron tiny oil mist particles.

• Customer value: Both large mechanical oil droplets and suspended ultra-fine oil mist (Aerosol) generated under high-speed operation can be fully coalesced and recovered, delivering efficient and stable performance under all working conditions.

4. Long service life and excellent resistance (reduces downtime for maintenance)

• Selling point: The designed service life can normally reach 4000 hours (when matched with high-quality air filters and lubricating oil) [1]. It adopts thickened perforated metal support mesh and high-temperature resistant epoxy resin adhesive.

• Customer value: It features strong impact resistance and will not break down or deform under alternating pressure. Resistant to corrosion by synthetic lubricating oil, it reduces material and labor costs caused by frequent production shutdowns for filter replacement.

5. Reliable anti-static safety design (eliminates explosion and fire risks)

• Selling point: The filter element is equipped with a built-in 100% conductive grounding structure (with conductive strips or metal pins) to ensure perfect contact between the whole assembly and the metal surface of the air compressor tank.

• Customer value: Static electricity is easily generated by friction of high-speed airflow. This design conducts static electricity away instantly, completely preventing safety accidents such as explosion and combustion inside the air compressor oil-gas tank triggered by static sparks.
