This high-pressure air compressor is a high-quality electrical machinery product developed by Bengbu United Compressor Manufacturing Co., Ltd. As a professional manufacturer specializing in the R&D and production of high-performance compression systems, our company has integrated advanced technology and rich industry experience into the R&D and production of this compressor. Designed specifically for industrial-grade application scenarios, the product excels in structural performance stability, operational efficiency, and adaptability, capable of meeting the diverse operational needs of different industries.
In terms of core parameters, this compressor uses air as the medium (100% air composition) with a processing capacity of 10 m³/min, making it highly suitable for large-scale industrial operations that require continuous and stable airflow. It operates at atmospheric inlet pressure and ambient inlet temperature, while achieving an impressive exhaust pressure of 25 MPa.G — a key technical indicator that enables it to efficiently handle various high-pressure industrial tasks. Driven by a 145 kW main motor, the compressor achieves a perfect balance between powerful output and energy conservation, ensuring reliable and stable performance even in harsh and demanding working environments.
This air compressor adopts a scientific multi-stage compression system (specific number of stages customizable) and is classified as a fan-shaped, air-cooled, single-acting piston compressor. Its main structural advantage lies in the optimized cylinder layout: eight cylinders are arranged in a [specific arrangement, e.g., double fan-shaped/in-line] structure, with the axes of adjacent cylinders forming a 45° angle. This reasonable layout ensures uniform mass distribution of the compressor's moving parts, significantly reducing the uneven mechanical stress on the machine body during operation and improving overall structural stability.
To further enhance operational stability, the compressor's crankshaft is equipped with high-precision balance weights. These balance weights can effectively offset the inertia torque generated by the reciprocating motion of the pistons and connecting rods, thereby reducing the vibration amplitude of the equipment. This not only lowers the noise during operation but also extends the service life of key components such as bearings and seals, reducing the frequency of maintenance and replacement. The crankcase is made of high-strength gray cast iron and serves two main functions: on one hand, it acts as an oil reservoir for lubricating oil to ensure continuous and sufficient lubrication of internal moving parts; on the other hand, it integrates practical maintenance interfaces, including four side inspection ports (facilitating inspection and installation of internal components), an oil level gauge (for real-time monitoring of lubricating oil level to prevent oil shortage), and oil filler ports (with built-in breathers to maintain internal pressure balance). These designs greatly simplify daily maintenance work and improve maintenance efficiency.
Efficiency and reliability are the core performance highlights of this air compressor. In terms of energy efficiency, its multi-stage compression ratio has been scientifically optimized (specific pressure ranges for each stage can be customized according to actual needs). This optimized design maximizes the utilization rate of motor power, reduces unnecessary energy loss during the compression process, and compared with other compressors with the same displacement and pressure parameters, it can significantly reduce long-term operating costs and bring considerable economic benefits to enterprises.
In terms of durability, the compressor benefits from high-quality component selection and reasonable structural design. Low-pressure stage cylinders (1st and 2nd stages) are made of wear-resistant gray cast iron, which can withstand long-term friction and ensure stable performance; the medium-pressure stage cylinder (3rd stage) uses QT600-3 ductile iron, which has high tensile strength and excellent impact resistance; the high-pressure stage cylinder (4th stage) is made of high-strength forged steel to cope with ultra-high pressure working conditions. In addition, the lubrication system integrates two efficient lubrication methods: pressure lubrication (for key components such as connecting rod big-end bearings and piston pin bushings to ensure sufficient lubrication) and splash lubrication (for cylinder walls and main bearings to achieve full-range lubrication coverage). This combined lubrication system not only ensures effective lubrication of all key components but also avoids the drawback of frequent oil changes associated with a single lubrication method, reducing maintenance downtime and improving the overall operational efficiency of the equipment.
Recognizing that industrial needs vary, the SF-10 / 250 (Motor Drive) is offered as a non-standard product, with tailored solutions available to match specific requirements. Customers can choose from multiple structural forms (D-type, M-type, S-type, V-type, etc.), cooling methods (water-cooled, air-cooled, or mixed cooling), and installation types (fixed, mobile, skid-mounted, or cabin-type).
Drive options include motor or diesel engine, ensuring compatibility with diverse power sources. Packaging is also customizable, with choices such as metal cabins, wooden boxes, or soundproof cabins to protect the unit during transit or suit on-site environmental needs. From design to production, our team collaborates closely with clients to align the compressor with their flow rate, pressure, purity, and usage environment demands.

The SF-10 / 250 (Motor Drive) is versatile across industries, including petrochemicals (e.g., ethylene production facilities), energy (oilfield operations, gas processing), manufacturing (high-pressure tooling), and infrastructure (pipeline maintenance). It has been successfully deployed in projects like Lanzhou Petrochemical’s ethylene capacity restoration and Kazakhstan’s Alibek oilfield development.
Thanks to its oil-free lubrication design and minimal vulnerable parts, maintenance frequency is significantly lower than traditional compressors. Routine checks (filter replacement, oil level inspection) are recommended every 3,000 operating hours, with major overhauls typically needed after 15,000–20,000 hours—depending on usage intensity.
