Xi Antianhou Company, founded in 1992, is a high-tech enterprise specializing in the research, development, production and sales of oil quality inspection and filtration products.

The company has always adhered to the business philosophy of "taking science and technology as the guide and taking energy saving as its own responsibility", made unremitting efforts in the field of oil quality inspection and filter products, and achieved fruitful results.

1992, the THY series oil quality detector developed by the company filled the gap in China, and all technical indexes exceeded those of similar foreign products. The appearance of this product has fundamentally solved the problem of "whether to change oil" that has troubled equipment management for a long time, and changed "regular oil change" into "oil change according to quality". In 2004, Tianhou Company and Boston Pre-filter Co., Ltd. jointly developed and produced "Jienengbao" series diesel purifiers, which were widely used in oil fields, fishing ports, various diesel vehicles and construction machinery, and caused a great sensation in the development of energy-saving products in the world. This product not only made a major breakthrough in the pre-filtration technology, but also effectively protected the engine, reduced the maintenance cost, reduced the exhaust emission, saved fuel by 5-20%, and had good oil-water separation function.

Excellent performance has made Tianhou Company widely concerned by the same industry and won many awards. National Innovation Fund, second prize of scientific and technological progress of the whole army, national high-tech enterprises, Xi 'an Top 100 Enterprises (25th) and 99 national patents have made Tianhou Company a star in the whole industry.
