We introduced a new and excellent technology coupled with advanced production equipment and strict means of testing. For your assurance, our factory has passed the certification of ISO 9001:2000.
Our company took the lead for the first time the piston ring technology applied in the roots blower. We have successfully developed the most advanced piston ring seal using a high advanced technology innovation. This greatly extended the replacement cycle from 6 months to 3 years and above. Also ensures no leakage in a variety of gases and at the same time reduce the maintenance and operation costs. In fact, our technology has broken the technology monopoly of a few big state-owned enterprises in China in the same industry. In addition, for the special gas industries such as natural gas/methane/carbon dioxide/sulfur dioxide/inflammable/explosive gases and high-pressure conditions our products are the best choice.
