Kaishan’s New Screw Host Certified Internationally Advanced by National Authority

March 13, 2026 – Kaishan Group Kaishan Heavy Industry has achieved a major technological breakthrough in compressor energy efficiency. Its ultra-efficient adaptive pressure-regulated horizontal two-stage screw airend, developed in-house by Kaishan Research Institute, has been officially certified as domestically leading and internationally advanced by a national-level expert committee.

The appraisal meeting was organized on March 9 by the Shanghai Technology Exchange, a national technology service institution jointly established by the Ministry of Science and Technology of China and the Shanghai Municipal Government. After rigorous review and testing, the expert panel unanimously concluded that Kaishan’s new screw host meets the highest global standards for energy efficiency and performance.

Compressors consume 8%–10% of China’s industrial electricity, making them a key target for energy conservation under the national 2030 Carbon Peaking Action Plan. Traditional two-stage compressors suffer from over-compression or under-compression under variable load conditions, wasting significant energy.

Kaishan’s innovation solves this problem with two core technologies:

This adaptive two-stage design delivers industry-leading energy savings, lowering operational costs for manufacturing, mining, and construction users worldwide.

Kaishan Group (stock code: 300257) is a global leader in compressed air and vacuum solutions. With 6 R&D centers worldwide and 500+ engineers, the company holds over 300 patents and has earned numerous national and international awards for innovation.

This certification marks another milestone for Kaishan in high-efficiency compression technology, reinforcing its position at the forefront of global industrial equipment innovation.
