SIPHON washing machine


Takahagi factory has produced the high quality filter media with focusing on the important role of filter media for the water supply system since the factory was established in 1940. Using our experiences which we cultivated for many years, we established the automation product system which is included a much of flexibility, reliability and efficiency. Under our concept, which is “Apart from conventional production technology which is depend on human resources and experiences”, our Takahagi factory was renovated in July, 1995 under T.F.A project (Takahagi Factory Automation project). After the renovation, we have produced a large amount of high quality filter media through 24 hours operation system. Also, we adopt out device “Siphon Tank” as a prototype model to filter and reuse the drain water in the factory for 24 hours, contributing to the environment. We would like to keep improving and developing our facilities to provide high quality and low price products with a short period of time.

YH-24A(Yasuhiro Hirotsugu 24hours Automation)
This is the Automation Producing System for filter media for 24 hours. YH is named from the name of the first president, Hirotsugu Saito, who gave us a know-how and the current president, Yasuhiro Saito, who innovates the cutting age technology.
