003765-004 (Common market alternative part number: HIFI OA1163, for information inquiry) is a high-performance coalescing oil-gas separator element specially designed for surface drill rigs, underground drill rigs and mobile high-pressure air compressor systems.
Key Product Advantages
• Ultimate Residual Oil Control (High Efficiency & Energy Saving):
Imported deep coalescing borosilicate glass fiber is adopted, with a filtration accuracy of up to 0.3 microns. Under rated working conditions, the residual oil content in exhaust gas can be strictly controlled within 3 ppm (parts per million). This not only protects downstream pneumatic tools from damage caused by oil contamination, but also significantly cuts the lubricating oil consumption cost of equipment.
• Excellent Collapse Resistance and Pulse Resistance:
Airflow impact inside mining drill rigs and high-pressure compressors is intense. Both the inner support frame and outer protective screen of this filter element are made of high-strength thickened electroplated steel plates. Combined with advanced spiral interlocking and punching processes, it can withstand extremely high pressure differentials and airflow pulses generated during instantaneous system startup, ensuring the filter element will not deform or rupture under high pressure differentials.
• Outstanding Temperature Resistance and Corrosion Resistance:
All metal components of the filter element undergo anti-corrosion electroplating treatment, and the core adhesive is special epoxy resin resistant to high temperature and high pressure. Even when immersed long-term in high-temperature synthetic compressor oil (such as PAO or PAG lubricants) at up to 120°C, the sealing adhesive layer and filter media will not age, peel off or decompose.
• Perfect OEM Original Equipment Interchangeability:
Manufactured in strict accordance with the original interface dimensions of Sandvik/Driltech (Height: 625mm / Outer Diameter: 245mm). It achieves 100% seamless replacement in physical dimensions and performance for both original parts and well-known replacement parts (such as French HIFI). It fits tightly during installation with no air leakage or oil leakage.
Installation Notes
Power off and depressurize fully. Clean housing and seal surface, check gasket. Insert element vertically. Tighten cap evenly. Test run no-load, check leakage, DP and oil carry-over.
Maintenance & Replacement
Monitor differential pressure, replace when DP rises. Check oil carry-over regularly. Use qualified lubricant. Store dry, discard damaged element.

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.
