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.
Installation Notes
Check that the Viton O-ring is properly seated. The 12 bolts (22 mm hole diameter) on the flange shall be tightened diagonally in several passes to ensure even stress distribution and prevent gas leakage on one side.
Maintenance & Replacement
Differential Pressure Compliance Replacement (Primary Criterion): When the differential pressure across the oil separator element reaches 0.8 ~ 1.0 bar, immediate replacement is required. At this point, the filter element is nearly clogged. Continued operation will lead to a sharp rise in power consumption and may even cause the filter element to collapse and fail. • Operating Hour Reference: Under normal working conditions, the designed service life of this filter element is generally 3000 ~ 4000 hours. However, if the factory is located in a high-dust environment or the air intake filtration is poor, replacement may be necessary at around 2000 hours.

Frequently Asked Questions
How do I confirm compatibility without a third-party brand reference?
Provide the product number, dimensions, connection details, operating conditions and equipment information. Our team will confirm the application.
Which dimensions should I measure?
Measure the overall height, outer diameter, inner diameter and thread or connection size. A photo or drawing helps confirm the replacement.
How do I choose the correct seal material?
Seal selection depends on the filtration media, operating temperature and chemical compatibility. We can confirm suitable options for your application.
Can you provide a product data sheet?
Yes. Send the product number and required specifications and we will provide the available data sheet and selection support.
