Air Oil Separator Filter DC3265

DC3265 is a high-performance air-oil separator filter designed specifically for industrial screw air compressors. It is mainly used in the final critical process of the compressor system, and its core task is to thoroughly separate the fine oil aerosol entrained in the compressed air, ensuring that the final discharged compressed air is clean and oil-free.

Core Functions and Working Principle

During the operation of a screw air compressor, lubricating oil is discharged together with high-temperature compressed gas, forming a large amount of fine oil mist.

1. Coalescence: The DC3265 filter element adopts an Out-to-In flow design. Compressed air containing oil mist enters from the outer side of the filter element.

2. Multi-layer Interception: The interior of the filter element uses multi-layer high-performance, ultra-fine borosilicate micro-glass composite filter media. As tiny oil droplets pass through these interlaced fibers, they are intercepted, collide and coalesce into larger oil droplets.

3. Gravity Oil Return: The lubricating oil coalesced into large droplets accumulates at the bottom of the filter element under gravity, and is drawn back to the airend through the oil return pipeline of the compressor system for recycling, while clean compressed air is discharged from the center of the filter element.

Technical Highlights and Product Advantages

• Ultra-low Residual Oil Content: With efficient separation by the DC3265 filter element, the oil content of compressed air at the outlet can be controlled within 1 ~ 3 ppm, greatly reducing the load on downstream precision filters.

• High-precision Multi-layer Filter Paper: It features an absolute filtration accuracy of 0.1 μm and a filtration efficiency up to 99.999%, which can effectively capture even the finest suspended oil mist particles.

• Excellent Energy Efficiency (Low Pressure Drop): Its structural design optimizes the airflow path. The initial pressure drop of a new filter element is only 0.15 ~ 0.25 bar. A low pressure drop means the air compressor does not need to consume extra electric power to overcome resistance, thus cutting the overall energy consumption of the unit.

• Robust Structure and Long Service Life: Reinforced metal support frames are fitted both inside and outside the filter element, withstanding a maximum ultimate pressure drop of 5 bar to prevent structural collapse under sudden high pressure. Meanwhile, the flange is equipped with high-quality anti-static gaskets and high-temperature and oil-corrosion-resistant Viton seals, delivering a stable service life of thousands of operating hours.
