1616630581: OFS O-21 AIR END

As an Atlas Copco distributor, we supply the genuine Atlas Copco 1616630581 OFS O-21 Air End — a factory-calibrated, brand-new original component sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd. Every unit we deliver carries full manufacturer traceability, ensuring you receive exactly what Atlas Copco designed, built, and certified.

Product Introduction

The air end stands as the undeniable heart of any screw air compressor, driving the essential process of converting ambient air into pressurized energy. Its precision, efficiency, and overall reliability directly determine the compressor’s performance, energy consumption, and operational lifespan.

The OFS O-21 designation signifies a unit with highly optimized, often asymmetrical, rotor profiles, high-precision bearings, and robust housing materials. Atlas Copco manufactures this air end with exceptional attention to detail, ensuring minimal internal leakage and maximum volumetric efficiency. Each OFS O-21 air end undergoes rigorous testing and balancing processes, which guarantee smooth rotation and minimal vibration during operation.

Manufactured with precision, the OFS O-21 element delivers stable airflow and guarantees oil-free air compressors, making it ideal for industries that require high-purity air. It improves efficiency by 35%, reduces maintenance downtime by 25%, and extends service life by 30% compared to conventional replacements.

Technical Specifications

Installation Steps

We recommend that all installation work be carried out by a qualified Atlas Copco service technician. The following steps provide a general procedural reference:

• Safety preparation — Shut down and fully isolate the compressor from all power sources. Depressurize the system completely and allow it to cool before beginning any disassembly.
• Remove the worn air end — Disconnect all oil lines, air inlet and outlet piping, sensor wiring, and motor coupling connections. Use appropriate lifting equipment rated for the 585 kg unit weight, and carefully extract the existing air end from the compressor frame.
• Inspect and prepare the new unit — Unpack the new OFS O-21 Air End and ensure all protective caps are removed. Inspect the air end for any transit damage. Apply a thin film of clean compressor oil to the rotor tips, bearing surfaces, and seals as required by the manual to aid in smooth startup.
• Position and align — Carefully lower the new air end into position on the compressor frame using lifting equipment. Align it precisely with the motor coupling and mounting points.
• Secure and torque — Secure all mounting bolts to the specified torque values, following a strict crisscross tightening sequence. Reconnect the motor to the air end, ensuring precise coupling alignment.
• Reconnect all lines and sensors — Reconnect all oil lines, air inlet/outlet piping, and sensor wiring. Replace all gaskets, O-rings, and seals with new, genuine parts during reassembly to ensure leak-free operation.
• Refill and verify — Refill the compressor with the correct type and quantity of genuine Atlas Copco compressor oil. Check all connections once more before powering up.
• Commissioning — Perform a no-load test run, verify pressure, temperature, and vibration readings, and confirm that all readings fall within Atlas Copco’s specified operating parameters before resuming full production load.

Frequently Asked Questions

Q1: What compressor models is the OFS O-21 Air End (1616630581) compatible with?
A1: The OFS O-21 Air End is a complete, factory-calibrated assembly specifically designed for seamless integration into designated Atlas Copco oil-flooded screw compressors. We recommend you verify the model compatibility with your Atlas Copco service documentation or contact us directly with your compressor serial number for confirmation.

Q2: Is this a brand-new, original product — not a refurbished or imitation part?
A2: Yes, absolutely. We source this air end exclusively from Atlas Copco (Shanghai) Trading Co., Ltd., the authorized Atlas Copco entity in China. Every unit is brand new, fully original, and carries complete factory traceability. We do not supply refurbished or imitation alternatives of any kind.

Q3: Why does using a genuine Atlas Copco air end matter compared to non-original alternatives?
A3: The genuine OFS O-21 element improves efficiency by 35%, reduces maintenance downtime by 25%, and extends service life by 30% compared to conventional replacements. Non-original parts frequently lack the precision rotor profiles and material quality needed to sustain these levels of performance, which leads to higher energy costs and premature failure.

Q4: How long can the OFS O-21 Air End operate before requiring major service?
A4: With proper maintenance — including regular oil changes and filter replacements — a genuine Atlas Copco air end can operate reliably for over 40,000 to 60,000 service hours before major overhaul is needed. Adhering to Atlas Copco’s recommended service intervals is the single most effective way to protect this investment.

Q5: What is the lead time and shipping arrangement for this product?
A5: Lead time depends on current stock availability at Atlas Copco (Shanghai) Trading Co., Ltd. Once we confirm availability, we coordinate professional export packaging suitable for the 585 kg unit, arrange freight with full insurance coverage, and provide all customs documentation including the HS Code 8414900090 and certificate of origin (Belgium). Contact us for a precise delivery timeline based on your destination.

Your compressor is only as reliable as the components inside it. When the air end fails or approaches end-of-life, every hour of downtime carries a real cost. We make it straightforward to get back to full capacity — with genuine Atlas Copco parts, transparent pricing, and an experienced team that handles sourcing, documentation, and logistics from start to finish.
