At recent international aquaculture and fishery equipment exhibitions held in China, domestically manufactured gearless permanent magnet variable frequency aerators have become one of the most popular product categories. They have attracted a large number of procurement merchants from Southeast Asia, the Middle East, and Latin America. Many Chinese manufacturers have launched new generation salt‑resistant permanent magnet aerators optimized for tropical seawater breeding environments. These units feature full 304 stainless steel floating frames and high‑performance permanent magnet materials.
On‑site technical demonstrations have shown oxygen transfer efficiency that compares favorably with conventional imported aerator products, offering a clear cost‑performance advantage over equivalent European and Japanese equipment. Importers from Vietnam, Thailand, Indonesia, and Malaysia have expressed strong interest, noting that their local intensive shrimp farming industries urgently need high‑efficiency energy‑saving aeration solutions to curb rising electricity costs. Chinese permanent magnet aerators meet the regional requirements for both energy savings and salt corrosion resistance.
Driven by the global trend toward aquaculture intensification and overseas energy‑efficiency policy upgrades, export orders for China’s permanent magnet aerators have grown steadily. In addition to finished aerator products, core permanent magnet motor spare parts are receiving OEM customization orders from overseas machinery factories. As domestic R&D capabilities in aquatic permanent magnet drive technology continue to improve, Chinese fishery equipment is moving from low‑end price‑based exports to high‑value‑added intelligent and energy‑saving products, further increasing its international market share.
