1616635688: O.F.S. Q-21

The Atlas Copco 1616635688 O.F.S. Q-21 Air End (Order Number: 1616716287) stands as one of the most reliable and precision-engineered core components in the industrial compressed air sector. Manufactured by Atlas Copco in Belgium — a country with a long-standing reputation for engineering excellence — this air end unit delivers the high-efficiency performance that demanding industrial environments require.

Brand Introduction

Atlas Copco, founded in 1873 and headquartered in Stockholm, Sweden, ranks among the world’s foremost manufacturers of air compressors, vacuum solutions, generators, pumps, power tools, and assembly systems. The O.F.S. Q-21 Air End reflects Atlas Copco’s decades of research and development investment in screw compressor technology. This component serves as the mechanical heart of oil-free screw compressors, directly responsible for the compression of air in critical applications across pharmaceutical manufacturing, food & beverage processing, electronics, and semiconductor production — sectors where even trace oil contamination is unacceptable.

We supply this product as a brand-new, genuine unit sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd., ensuring full supply chain traceability and authentic product integrity.

Why Choose the Atlas Copco O.F.S. Q-21 Air End

1. Oil-Free Compression Technology

The “O.F.S.” designation stands for Oil-Free Screw, which means this air end produces 100% oil-free compressed air that meets ISO 8573-1 Class 0 certification standards. This makes it the first choice for industries where air purity is a regulatory and operational requirement.

2. Engineered for Long Service Life

Atlas Copco engineers this air end with robust internal tolerances, high-grade rotor coatings, and precision-balanced components. The design minimizes mechanical wear over extended duty cycles, reducing total lifecycle cost for operators who run continuous or near-continuous production lines.

3. Energy Efficiency

The Q-21 profile rotor design optimizes the compression cycle to reduce specific energy consumption. Operators in energy-intensive facilities benefit from lower electricity costs per unit of compressed air produced compared to older generation components.

4. Global Support Network

Atlas Copco maintains service centers and certified technicians across more than 180 countries. Choosing a genuine Atlas Copco air end guarantees access to this worldwide support infrastructure, as well as compatibility with original Atlas Copco service kits, seals, and bearings.

5. Full Supply Chain Authenticity

We source this unit exclusively through Atlas Copco (Shanghai) Trading Co., Ltd. — the authorized trading arm of Atlas Copco in China. Every unit ships with original packaging, full product identification markings, and traceable documentation.

Compatible Applications

The O.F.S. Q-21 Air End integrates into Atlas Copco oil-free rotary screw compressor platforms and suits the following industries:

• Pharmaceutical & Biotechnology — sterile process air, fermentation, and packaging lines
• Food & Beverage — direct contact applications requiring zero oil carryover
• Electronics & Semiconductor — cleanroom environments with ultra-pure air requirements
• Automotive Manufacturing — paint booth and precision assembly air supply
• Chemical & Petrochemical — process air where hydrocarbon contamination must be eliminated
• Textile Industry — air-jet weaving and pneumatic handling systems

Installation Guidelines

Proper installation protects performance and preserves warranty coverage. We recommend that qualified Atlas Copco-certified technicians carry out all installation and commissioning work. The general procedure involves the following stages:

• Step 1 — Pre-Installation Inspection: Upon delivery, inspect the outer packaging for transit damage. Verify the part number (1616635688) against the packing list. Check that all factory protective plugs and covers remain in place.
• Step 2 — Mounting Preparation: Prepare a clean, level installation surface capable of supporting a minimum static load of 1,000 kg. Ensure sufficient clearance on all sides for airflow and future service access.
• Step 3 — Alignment: Use precision alignment tools to align the air end shaft with the drive motor or gearbox coupling. Misalignment exceeding manufacturer tolerances causes premature bearing failure and voids the warranty.
• Step 4 — Fluid and Cooling Connections: Connect inlet filtration, cooling water circuits, and condensate drainage lines strictly according to the applicable Atlas Copco installation manual. Verify that inlet air quality meets the design specification.
• Step 5 — Commissioning: Perform a dry rotation check before initial start-up. Run the unit unloaded for the manufacturer-specified break-in period. Check vibration levels, temperature readings, and outlet pressure against rated parameters before handing the system over to production.

Important Precautions

Use only Atlas Copco genuine spare parts during servicing. The use of non-genuine parts will immediately cancel all warranty claims and may compromise system safety.

Do not operate beyond rated conditions. Exceeding design pressure, temperature, or speed limits causes irreversible internal damage.

Ensure proper inlet filtration. Particulate ingestion into the air end causes scoring of rotor surfaces and accelerated wear.

Follow the specified maintenance intervals for rotor coating inspection, bearing lubrication, and seal replacement.

Store correctly if not immediately installed. Maintain the unit in its original packaging in a dry, temperature-controlled environment, and rotate the shaft periodically according to Atlas Copco’s storage guidelines.
