3,NC Machine or numerical control equipment, automatically performs parts machining through pre-programmed instructions without manual operation. Its core advantages include high machining accuracy, stable quality, and significantly higher efficiency than traditional manual machine tools, with the ability to complete multiple processes automatically. When the workpiece changes, only the program needs to be replaced, offering great flexibility and making it widely suitable for multi-variety, small-batch manufacturing scenarios such as automotive, aerospace, and mold making.

4,5-Axis Simultaneous Machining with single clamping and five-face machining, the workpiece requires only one setup to complete all surface operations except the bottom, which eliminates positioning errors caused by repeated clamping and greatly enhances both accuracy and production efficiency. This system excels in machining complex spatial surfaces, making it particularly well-suited for components such as impellers, blades, propellers, and mold cavities.

5,A CNC planer is a machine tool that uses numerical control technology to perform planing operations, cutting workpiece surfaces through the linear reciprocating motion of the tool relative to the workpiece.It is primarily used for machining flat surfaces, grooves, and contoured surfaces of large mechanical parts, such as horizontal surfaces, vertical surfaces, inclined surfaces, curved surfaces, T-slots, and V-slots. It offers particular efficiency advantages when machining narrow and long surfaces.

6,"CMM" generally refers to the Coordinate Measuring Machine, a high-precision measurement device used in modern manufacturing to inspect whether the dimensions, shapes, and positions of components meet quality requirements. In simple terms, it is one of the key tools for ensuring product quality.Its core working principle involves using a movable probing system to capture the three-dimensional spatial coordinates (X, Y, Z values) of tens of thousands of discrete points on the workpiece surface. Specialized software then performs mathematical calculations and fitting on these points to reconstruct geometric elements such as points, lines, circles, cylinders, and curved surfaces, and to determine their dimensional, form, and position tolerances (e.g., roundness, parallelism, perpendicularity, coaxiality, etc.).

B-Tohin Mechanical – Built for the World
30 Years of Excellence in Air Power Solutions
Founded in 1994, Bester Mechanical (Jiangsu) Co., Ltd. is a Sino-foreign joint venture located in China's Yixing Environmental Protection Science and Technology Industrial Park. With a registered capital of RMB 120 million and a team of around 300 professionals, we have spent three decades perfecting our craft in air power equipment.
Our portfolio covers Roots blowers, rotary blowers, single-stage high-speed centrifugal blowers, air-foil and magnetic-bearing centrifugal blowers, screw blowers, and vacuum pumps – serving industries from water treatment and chemicals to power generation, building materials, and metallurgy.
Technology-Driven Product Excellence
Backed by the Jiangsu Provincial Engineering Technology Research Center for Energy-Saving Air Power Equipment, our R&D team includes professor-level engineers and doctoral researchers, with multiple national patents to our name.
Precision is at our core. We operate Japanese horizontal machining centers, fully automated CNC systems, and high-accuracy CMM inspection equipment – ensuring every component meets global standards. Our certifications include ISO9001, ISO14001, and ISO45001, and we are proudly recognized as a National High-Tech Enterprise and Jiangsu Provincial "Specialized and Sophisticated" SME.
A Product Line for Every Need
Roots Blowers (BK/BKW Series) – Our flagship three-lobe design integrates integrated rotor-shaft casting and American CR oil-seal technology. The optimized rotor profile cuts energy consumption by 15–20% while ensuring rock-solid reliability – a long-time favorite in wastewater treatment and pneumatic conveying across China.
Rotary Blowers (HC-S Series) – Compact, quiet, and self-lubricating via pressure differential. Ideal for precision applications like lab aeration and printing.
High-Efficiency Centrifugal Blowers – Our single-stage high-speed, air-foil, and magnetic-bearing centrifugal blowers represent the future of green air power – delivering superior energy savings and low-noise operation for large-scale projects.
In 2021, we acquired Wuxi Yiyou Electromechanical, launching a dual-brand strategy (Bester + Yiyou) to serve a broader range of customers and budgets.
15+ Years of Global Reach – Certified for International Markets
We began our international journey over 15 years ago and today proudly export to regions including Southeast Asia, the Middle East, Africa, and South America, with a growing presence in European markets.
CE Certification (2025) – Our screw blower series earned EU CE certification, clearing the path to European markets and underscoring our commitment to world-class safety and quality.
Global Heritage – As a joint venture with early technical cooperation ties to Japan's Toho Kogyo and the U.S.-based TUTHILL Corporation, we bring decades of cross-border collaboration and international manufacturing insight to every product.
Proven Performance Worldwide – Our blowers are trusted in major infrastructure projects across the globe, from municipal wastewater treatment plants to industrial power facilities, delivering reliable performance in diverse climates and demanding conditions.
Quality You Can Rely On
Every unit undergoes 100% inspection before shipping. Our advanced production lines, stringent quality control protocols, and commitment to continuous improvement ensure our machines perform consistently – whether in tropical heat, freezing cold, or anywhere in between.
Bester Mechanical – 30 years of experience, global certifications, and a passion for reliable, energy-efficient air power. We deliver solutions that work, anywhere in the world.
