Manufactured by Bengbu United Compressor, a leading industrial equipment supplier in China, the WW-3/40 High Pressure Air Compressor is a state-of-the-art solution engineered for high-demand scenarios that require stable, efficient air compression. It integrates advanced three-stage compression technology, featuring a W-shaped, air-cooled, single-acting piston structure. Six cylinders are arranged in a double W configuration (with a 60° angle between cylinder axes), which ensures optimal operational balance and significantly reduces vibration—critical for long-term industrial use.
At the core of its performance, the WW-3/40 delivers impressive specifications: a processing capacity of 3 m³/min (180 m³/h), inlet pressure of atmospheric pressure, inlet temperature of ambient temperature, and an exhaust pressure of 4 MPa.G (gauge pressure). Powering this robust unit is a YC6A210L-D20 diesel engine that operates at 1500 r/min and provides 185 kW of main motor power, guaranteeing consistent output even in harsh environments like remote oilfields or heavy manufacturing sites. Its modular design supports both stationary and mobile applications, making it adaptable to diverse operational needs.
The WW-3/40 is built to withstand industrial wear and tear. Its three-stage compression system—with two cylinders per stage—enables gradual pressure buildup, maximizing efficiency while minimizing stress on components. The W-shaped six-cylinder layout, paired with balance weights on the crankshaft, reduces inertia moments, lowering vibration and extending the lifespan of critical parts. The crankcase, made from high-grade gray cast iron, stores lubricating oil for seamless operation and includes essential interfaces: oil drains, temperature measurement ports, and breathing ports. A double middle body structure prevents oil contamination in the cylinder, ensuring clean air output—a key advantage for applications requiring high air purity.
This compressor prioritizes operational efficiency and ease of upkeep. Its air-cooled design eliminates the need for complex water cooling systems, simplifying installation and cutting operational costs. With fewer vulnerable parts, the WW-3/40 operates at low noise levels (thanks to balanced components) and requires minimal maintenance, reducing downtime for industrial processes. Automation features further enhance usability, allowing seamless integration into existing workflows. The entire unit—including main and auxiliary equipment—is mounted on a skid, ensuring smooth operation and easy transportation for on-site projects.
To meet diverse industrial requirements, the WW-3/40 offers flexible customization:
• Structural forms: Choose from D-type, M-type, S-type, V-type, or Z-type configurations to match site layout and space constraints.
• Cooling methods: Select air-cooled (standard), water-cooled, or mixed cooling systems based on local climate and efficiency needs.
• Installation types: Opt for fixed, mobile, skid-mounted, or cabin-type setups, adapting to stationary facilities or remote on-site work.
• Drive options: The standard diesel engine can be replaced with a motor-driven system, depending on power availability at the project site.
• Packaging & transportation: Options include sea, air, or land transport, with packaging in metal cabins, wooden boxes, or soundproof cabins.
The WW-3/40 incorporates proprietary technologies backed by Chinese utility model patents, ensuring reliable performance:
• Piston rod thread protective sleeve (Patent No.: ZL 2017 2 1907021.7)
• Piston ring support device (Patent No.: ZL 2018 2 0294776.2)
• Range piston for symmetrical balanced compressors (Patent No.: ZL 2017 2 190177.0)
• Integrated long-short double compartment (Patent No.: ZL 2018 2 0294762.0)
 |  |  |  |
| Has high efficiency, strong reliability, and high degree of automation; | Less vulnerable parts, low vibration, low noise, and easy operation and maintenance | The main and auxiliary equipment of the compressor are all installed on the sled, running smoothly and reliably. The overall sled installation is convenient for the transportation and installation of the compressor | The entire machine components are carefully designed |

The WW-3/40 High Pressure Air Compressor is primarily optimized for oil extraction projects, where it excels in three key operations:
• Pipeline pressure testing: Delivers stable high-pressure air to verify pipeline integrity, preventing leaks in oil transport networks.
• Line sweeping: Removes debris and contaminants from pipelines, ensuring unobstructed oil flow and maintaining operational efficiency.
• Gas lift operations: Injects high-pressure air into oil wells to lift oil to the surface, boosting recovery rates in mature or low-pressure wells.
Beyond the oil industry, the compressor serves as a reliable gas source for any project requiring 3 m³/min air volume and pressure up to 4 MPa.G (with adjustable pressure for lower-demand scenarios). Its durability makes it suitable for sectors like mining (for pneumatic tools), heavy manufacturing (for metal fabrication), and large-scale construction (for concrete spraying), where consistent high-pressure air is essential.
