大巧技研 Company Profile

A microbubble generator that aerates water with remarkable efficiency. It revitalizes water, significantly promoting the growth of aquatic organisms and plants!

Daiko Giken Co., Ltd. was founded in 1987 as a company (Daiko Giken Limited) that specializes in the installation of equipment for special gases, medical gases, and liquefied petroleum gases. In April 2010, we established the Eco Bubble Division and began joint research and development of microbubble generation devices with Professor Hiroaki Tsutsumi from Kumamoto Prefectural University. In July 2011, we obtained a domestic patent for the fine bubble generation nozzle DDHRS (double vortex high-speed rotating gas-liquid mixing double tank) and started selling the microbubble generation device (eco-bubble®-400) equipped with one DDHRS nozzle in November of the same year. We have also obtained patents in the United States, China, and South Korea. Subsequently, we developed and released the freshwater submersible pump integrated model eco-bubble®-250, the compact model eco-bubble®-S series, and the pump-nozzle separated model eco-bubble®-N series. By selecting from these models, we can accommodate a wide range of applications, from aeration of water in tanks of 10 to 20,000 liters to wastewater treatment facilities in outdoor settings and aeration of water in aquaculture facilities of 10,000 m³. In December 2020, we changed our company name to Daiko Giken Co., Ltd.
