1616754080 (=1616754090): OIS Q-05 STAGE

We as an Atlas Copco distributor in China, supplies the brand-new and original Atlas Copco 1616754080=1616754090 OIS Q-05 Air End — a high-performance compression element engineered specifically for Atlas Copco oil-injected rotary screw air compressors.

Product Introduction

The Atlas Copco 1616754080=1616754090 OIS Q-05 Air End serves as the core compression element at the heart of your compressor system. It generates compressed air with stable pressure output, high mechanical efficiency, and consistent long-term reliability. The OIS series incorporates an optimized oil injection system that effectively seals internal clearances and dissipates compression heat, reducing the specific energy requirement of your compressor. Manufactured in Belgium (Origin: BE), this air end reflects Atlas Copco’s world-class engineering heritage and meets the rigorous demands of continuous industrial operation across manufacturing, energy, automotive, chemical, and heavy engineering sectors.

This product is sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd., ensuring every unit is 100% genuine, factory-fresh, and backed by Atlas Copco’s global quality standards. The part number 1616754080 appears on the product nameplate, while 1616754090 serves as the order number used when placing procurement requests through the Atlas Copco system. Both numbers refer to the identical physical component — there is no difference in specification, content, or performance between the two designations.

Product Parameters

Product Advantages

1. Genuine Belgian Manufacturing
The OIS Q-05 Air End originates from Belgium, reflecting Atlas Copco’s highest-tier production standards. Every component undergoes precision engineering under strict dimensional tolerances, giving you full confidence that the unit you receive delivers the same performance as the original factory-installed element.

2. Optimized Energy Efficiency
Users typically experience energy savings of 8% to 15% after replacing a worn air end with this genuine unit, directly impacting operational costs. The optimized rotor profile minimizes internal leakage and reduces pressure drop across the compression stage, ensuring your system operates at peak efficiency throughout the service life of the unit.

3. Exceptional Structural Durability
Atlas Copco constructs the housing from high-grade cast iron with reinforced structural ribs. This robust design withstands high operating pressures and ensures dimensional stability under continuous heavy-duty cycles. The material selection provides excellent corrosion resistance and dampens vibration, extending bearing life and reducing mechanical wear by an estimated 20% compared to non-genuine alternatives.

4. Strict Quality Assurance
Atlas Copco applies strict quality control throughout manufacturing and final inspection. Each OIS Q-05 Air End undergoes dimensional checks and functional validation before release. We supply this product with clear product identification, original packaging, and full traceability, giving every buyer complete confidence in authenticity and quality.

5. 12-Month Warranty Coverage
Each unit comes with a 12-month warranty against defects in design or production, providing reliable after-sales support. Please note that misuse, improper fitting, and normal wear and tear are excluded. Using spare parts other than Atlas Copco’s genuine spare parts will lead to cancellation of any warranty claims.

6. Immediate Performance Restoration
Because this is a genuine Atlas Copco air end with exact factory dimensions and rotor specifications, your compressor returns to its original performance specification immediately upon installation — no break-in adjustments or calibration delays.

Precautions and Operating Steps

Important Precautions Before Replacement

1. Always confirm that the replacement air end model and part number match your specific compressor serial number before proceeding. Contact us if you need confirmation.
2. Only qualified and trained technicians should perform air end replacement. Improper fitting voids the warranty.
3. Never attempt replacement while the compressor is energized or pressurized. Full de-energization and pressure relief are mandatory.
4. Use only genuine Atlas Copco spare parts, tools, and lubricants throughout the replacement process. Using non-genuine components cancels warranty coverage.
5. Allow the compressor to cool completely before beginning any disassembly work to avoid burns and thermal-expansion-related fitting errors.
6. Prepare a clean, dry working area. Contamination introduced during installation can cause premature failure.

Step-by-Step Replacement Procedure

• Step 1: Shut Down and Isolate. Power off the compressor completely and engage the lockout/tagout procedure. Disconnect the main electrical supply and allow the system to depressurize fully. Confirm zero pressure at all gauges before proceeding.
• Step 2: Drain Oil and Coolant. Drain all compressor oil from the oil sump, cooler circuit, and oil separator tank into an approved collection container. Dispose of used oil according to local environmental regulations.
• Step 3: Disconnect Pipework and Hoses. Label and photograph all connected air, oil, and coolant lines before removal. Carefully disconnect the inlet pipework, discharge pipework, oil supply lines, and all associated hoses. Cap open ports immediately to prevent contamination.
• Step 4: Remove the Drive Coupling. Disconnect the drive coupling or belt between the motor and the air end. Refer to your compressor’s service manual for the specific coupling type and removal procedure.
• Step 5: Unbolt and Remove the Existing Air End. Remove all mounting bolts securing the worn air end to the compressor frame. Using appropriate lifting equipment rated for the unit’s weight (904 kg), carefully extract the old air end and set it aside for disposal or return.
• Step 6: Inspect the Mounting Frame. Clean the mounting surface thoroughly. Inspect for any cracks, corrosion, or misalignment on the frame, and correct any issues before installing the new unit.
• Step 7: Install the New OIS Q-05 Air End. Using rated lifting equipment, lower the new air end carefully onto the mounting frame. Align all bolt holes precisely and hand-tighten all mounting bolts before applying final torque values as specified in the Atlas Copco service manual. Do not force the unit into position.
• Step 8: Reconnect All Lines and Couplings. Reconnect drive coupling, all oil lines, air pipework, and coolant hoses in reverse order of disassembly. Verify all fittings are tight and correctly oriented. Replace any seals or gaskets that show signs of wear.
• Step 9: Refill with Genuine Atlas Copco Oil. Fill the system with the correct grade and quantity of genuine Atlas Copco compressor lubricant. Using non-genuine oil may void warranty coverage.
• Step 10: Commissioning and Test Run. Before full-load start, perform a no-load test run to check for oil leaks, unusual vibration, or abnormal noise. Monitor operating temperature and pressure during the first 30 minutes of operation. Confirm all parameters fall within the manufacturer’s specified range before returning the compressor to production service.
