Product Advantages
1. Genuine Belgian Manufacturing Quality
The country of origin is Belgium, reflecting Atlas Copco’s world-class European manufacturing standards. Atlas Copco engineers the OIS O-05 C190 with precision-machined screw rotors and optimized internal geometry, ensuring that tolerances meet the exact factory specification required for peak compression performance. The robust cast iron housing delivers excellent thermal stability, dampens operational vibration, and resists corrosion under continuous heavy-duty cycling.
2. Superior Energy Efficiency
The air end features an optimized rotor profile that minimizes internal leakage and reduces pressure drop. Its robust cast iron housing provides excellent thermal stability and dampens operational vibrations. The OIS O-05 incorporates an advanced oil injection system that simultaneously seals rotor clearances, absorbs compression heat, and lubricates all moving surfaces. The air end improves compression efficiency by up to 15%, helping users lower overall energy consumption. For high-power installations operating continuously, this translates into significant reductions in annual electricity costs.
3. Guaranteed Authenticity and Traceability
Each air end arrives in original packaging with full traceability from Belgium (Origin: BE), guaranteeing 100% authenticity with every shipment. We source this unit exclusively from Atlas Copco (Shanghai) Trading Co., Ltd., ensuring that every product is brand new and carries valid factory warranty coverage. The GA series is ISO 9001, ISO 14001, and ISO 1217 compliant, delivering long and trouble-free operation at the lowest operating cost.
4. Direct Drop-In Replacement with Zero Compromise
This genuine air end installs directly into compatible Atlas Copco oil-injected screw compressor platforms without modification. This level of precision engineering ensures that when you install this genuine Atlas Copco air end, your compressor returns to its original performance specification immediately and maintains that performance reliably over an extended service period.
5. Professional Logistics and After-Sales Support
We packs the OIS O-05 C190 in a purpose-built seaworthy wooden export case, protecting the unit during international transport. Our technical team provides professional installation guidance and after-sales support to ensure smooth commissioning at your facility.

Customer Reviews
Review 1 — Plant Maintenance Manager, Automotive Manufacturing: “We installed the Atlas Copco OIS O-05 C190 air end three months ago to replace a worn unit on our GA 160 line. The fit was perfect, start-up was immediate, and our energy meter confirmed roughly 13% lower power draw within the first week. Highly recommend Sekes for genuine parts.”
Review 2 — Procurement Engineer, Petrochemical Plant: “Sekes delivered the 1616734581 air end in perfect condition with full documentation. Installation took less than a day, and the compressor has run flawlessly at full load ever since. Knowing it came direct from Atlas Copco Shanghai gives us complete confidence in authenticity.”
Review 3 — Operations Director, Mining Contractor: “After trying non-genuine parts with poor results, we switched to this original Atlas Copco C190 air end from Sekes. The difference in vibration levels and output stability was immediately noticeable. Two years in and zero unplanned downtime — exactly what we needed.”
