It is 60 kilometers from Guangzhou International Airport and 30 kilometers form Shenzhen International Airport Shenzhen, China, which shares a border with Kowloon, Hong Kong. Involved in manufacturing high quality compressors, the company is a one-stop-shop for design, production, sales and after-sales service. Two brands produced by the company are Xin Yong Shi (New Warrior Brand) and Yong Shi (Warrior Brand). The company currently holds 6 technical patents and has plans for additional patent applications. We have a 2,000 square meter factory and over 30 employees. Our factory produces 2,000 units per month. Our factory has state of the art equipment including 5 CNC milling machines, an industrial dimension-verification microscope, a 1,000psi pressure tester, fatigue tester and multi-function compressor test lines. Our first water-cooled 30mpa compressor was developed and produced in large quantities in 2011. As of June, 2017, we have sold more 10,000 compressors.


Our product range includes: high-pressure air compressors; manual high-pressure water cooling pumps; 4500psi and 12-voit high-pressure compressors. The main applications of our compressors are for air-gun shooting competitions stress tests, sealing and leak-pressure tests, military and defense applications and any other field or endeavor requiring compressed air.

Our Technical Team

The technical research team at Sumei is led by James Luo, an experienced mechanical engineer who has worked or consulted for various Fortune 500 companies.Between 2014 and 2016, James and team spent time energy researching and testing various aspects of compressor parts and specifications. Many companies produce compressors-copying existing designs-but-low-quality products, James Luo was intent on making better compressors.The Sumei tech team worked tirelessly on R&D to find ways to extend motor life, as well as developing and testing methods of heat and noise reduction. Various materials were tested for resistance to wear and tear. Valve durability and stability were tested also, as well as varying the sizes of core parts to test and enhance changes in compressor performance.The final designs and evaluations, backed up by research, data and test results, have shown unbeatable continuous high strength durability. For example, the main motor shaft in average motors will fail between 100 and 250 uses. The Sumei specially-designed and manufactured motor shaft, made from high-temperature, heat-treated, reinforced steel has, so far, tested at over 1000 uses. And the testing continues with even more positive results´╝ü
