The SF-10/250 skid-mounted air compressor is a high-performance industrial solution engineered for demanding high-pressure air supply applications. Designed with precision engineering and advanced cooling technology, it delivers stable, reliable, and efficient performance in complex and harsh industrial environments — making it ideal for projects that require continuous and consistent high-pressure air sources.
High-Pressure Capability: Provides an exhaust pressure of 25 MPa.G, meeting the operational needs of pipeline testing, pigging, gas lifting, and other high-pressure engineering tasks.
Flexible Operation: Adjustable pressure control allows operators to fine-tune settings based on project requirements, ensuring versatility and energy efficiency.
Robust Performance: Driven by a 145 kW motor, the system ensures powerful output and stable operation even during long-term, continuous workloads.
High Volume Flow: Processes 10 m³/min of 100% pure air, making it suitable for medium to large-scale industrial operations.
Plug-and-Play Design: Operates at atmospheric inlet pressure and temperature, reducing the need for additional pre-treatment equipment and simplifying on-site installation and operation.
The SF-10/250 compressor is widely used across industries, including:
Pipeline pressure testing and pigging
Gas lift operations in oilfield development
Industrial projects requiring high-volume air at pressures ≤25 MPa
Other engineering applications and industrial sectors that demand stable, high-pressure compressed air.
Equipped with a full air-cooled design, the SF-10/250 ensures efficient heat dissipation for both the cooler and the compressor cylinders.
The cooling assembly features a high-speed fan (1980 r/min), cooler, and protective air duct cover.
The fan drive uses a belt-driven system for reliable power transmission, with easy tension adjustments for stable operation.
Key components are equipped with straight-through pressure grease cups for easy maintenance using No.4 calcium-based grease, ensuring smooth operation of all moving parts.
The SF-10/250 excels in efficiency, durability, and adaptability:
Energy Efficiency: Optimized compression technology and power matching balance energy use and output. While delivering 10 m³/min air flow and up to 25 MPa.G exhaust pressure, it reduces long-term energy costs by 8–12% compared with similar models.
Durability: Critical components are made with premium, wear-resistant materials. Cylinders use heat-resistant gray cast iron, while the forged steel crankshaft provides exceptional tensile strength, ensuring stability during high-speed operations.
Dual-Lubrication System: Combines pressure lubrication for high-load components (such as connecting rod bearings and piston pins) with splash lubrication for cylinder walls and main bearings. This dual system extends service life by 30% compared to single-lubrication systems while reducing oil change frequency and maintenance downtime.
Easy Installation: The integrated skid-mounted design eliminates complex on-site assembly. Only simple pipe and electrical connections are required, enabling commissioning within 4–6 hours and saving time and labor costs.
Mobility: Compact dimensions allow for easy transportation via road, rail, or container shipment, meeting the mobility requirements of projects in oilfields, construction sites, and other demanding environments.

Whole Machine Description
All core components—including the compressor unit, coupling, 145 kW Y315M2-6 main motor, Y100L1-4 oil pump motor, piping system, control instruments, electrical systems, and auxiliary devices—are pre-installed on a unified skid base. This compact, balanced layout ensures high load-bearing capacity, minimizes vibration-related displacement during operation, and enhances overall structural stability.
To further improve operational reliability, the unit adopts a dedicated full air-cooling system. The cooling assembly—comprising a high-efficiency fan, multi-channel cooler, and enclosed air duct cover—ensures efficient heat dissipation for both the cooler and compressor cylinders. The fan, driven by the compressor crankshaft via a belt at 1980 r/min, features an adjustable tension system to maintain consistent belt tightness for stable power transmission and optimal cooling performance.
For lubrication, straight-through pressure grease cups are installed on the tension pulley, gland, and fan pulley housing, allowing easy injection of No. 4 calcium-based grease to keep moving parts smoothly lubricated and prevent wear caused by dry friction.
A key structural advantage is the independent cylinder protection design, which isolates the cylinder from the lubrication system. This prevents oil contamination of the compressed air—an essential feature for oil-sensitive operations, such as pipeline pressure testing and gas lift applications.
The high-strength gray cast iron crankcase serves dual functions:
Acting as a sealed oil reservoir for stable lubrication supply
Offering convenient maintenance access with side inspection ports, a real-time oil level gauge, and a breather-equipped filler port to balance pressure and prevent leaks.
This thoughtful design significantly simplifies daily maintenance and enhances equipment uptime.
