Overview of mainstream domestic piston compressor manufacturers
as a traditional high-efficiency positive displacement gas booster compressor, piston compressor is widely used in chemical industry, refrigeration, air separation, mining, energy and other fields. A group of manufacturing enterprises with mature technology, complete qualification and perfect service have been formed in China, covering small and medium-sized general-purpose models to high-pressure special models.
Representative manufacturer type
- backbone enterprises of state-owned enterprises: for example, the compressor units under Shenyang Blower Group (Shen gu) and Shaanxi Blower (Shaanxi drum) have large project integration capabilities and military-level quality control;
- professional manufacturer: Zhejiang Ningbo Oaks, Jiangsu Nantong Hengli, Shandong Weifang Fuyuan and other companies focus on the research and development of medium and low voltage piston machines, with high cost performance and fast after-sales response;
- manufacturers in special fields: Chengdu Yingge and Shanghai Hanzhong precision machine have independent patented technology in terms of oil-free/low-oil Piston Machines for CNG filling stations and refrigeration systems.
Selection and purchase suggestions
we recommend that you pay attention to the following items:GB/T 10893-2023 standard compliance of general reciprocating piston air compressor, energy efficiency level (IE3 and above are preferred), material certification of key components (crankshaft, piston ring, air valve), and whether customized pressure/exhaust/explosion-proof configuration support is provided. We do not recommend that you use low prices as the sole basis for judgment.
