At the beginning of 2025, Tongrui's oil filter business has achieved a good start, with strong production and sales momentum. The various transformer oil vacuum filters produced by the company, including popular models such as ZJA-ZX100, ZJA-ZX150, ZJA-ZX200L, and ZJA-ZX50, have gained high recognition in the global market for their vacuum dehydration, degassing, and precision filtration performance.

At present, the product has been successfully exported to multiple emerging markets such as Mexico and Africa to ensure the safe and stable operation of local power infrastructure. The continuous growth of overseas orders, especially the situation where some models are in short supply, fully demonstrates the international competitiveness and brand influence of Tongrui products. The company is accelerating production by optimizing production lines and improving efficiency, fully ensuring the delivery needs of customers at home and abroad. This round of sales boom has laid a solid foundation for the company to achieve leapfrog growth in annual performance, and also marks a crucial step for China's oil filtration equipment on the path of internationalization.
