SRET, a manufacturer of filter & filter system, which has grown steadily for the past two decades thanks to your encouragement and support.
SRET is manufacturing environment-friendly products ranging from frying oil filters for food companies to a variety of filters for paint, ink, waste water, and academic researches. In the case of frying oil filters, our efforts to reduce costs resulted in lower production costs, whereas, in the case of industrial and wastewater filters, our continued endeavor to improve product quality enabled us to manufacture products of much higher quality. For the past twenty years our company has been specializing in production of filters only.

Thereby SRET have our own unique know-how as regards filtration methods and technology, and we are able to make and supply filtration equipments that are customized to meet the needs and wants of individual customers.
I have made several overseas trips to compare our filtration equipments with those of our foreign competitors, and my conclusion was that our products were never inferior to our foreign counterparts' in terms of technology, and ours were very price-competitive.

SRET have started with industrial filters, but  SRET have developed the frying oil filters, which can filter waste cooking oil, for food companies, and SRET have been supplying them to several food companies. In that the newly developed frying oil filter will help cut spending on cooking oil, whose price continues to rise in recent years, and help consumers use the same quantity of cooking oil almost twice as long, it is very popular among many food companies.

SRET is meeting the requirements of not only companies that use frying oil such as companies making fish balls and cakes and confectionary companies, but also firms that need filters such as cosmetics and environment companies.
