Motor Division Overview
In 1968, through a technical alliance with Germany’s PAPST company, we became the first in Japan to manufacture and sell compact metal fan motors for cooling applications. Since its establishment, the Motor Division has remained committed to domestic production in Japan. We offer a wide range of products, from axial fans to blowers and cross-flow fans, with a focus on metal blade types. We also provide a diverse lineup of fan sensors as our core product group.
