Our company was established as Sanwa Shiki Ventilator Co., Ltd. after separating from the manufacturing division of Sanwa Kogyo Co., Ltd. Initially, we mainly manufactured and sold rotary and fixed ventilators, as well as fireproof hoods. We contributed to the development of local industries and built a solid foundation through the trust we received from related parties. Currently, we focus on the development of pressure-resistant explosion-proof ventilators for factories and hazardous material warehouses, as well as creating comfortable environments through ventilation in architectural spaces within the industrial sector. We are also dedicated to the research and development of rooftop ventilation systems and the manufacturing and sales of products tailored to environmental needs, such as Sanwa Hatches. In the future, alongside the research and development of ventilators, we aim to advance the research of hatches for industrial and residential use. Our entire team is committed to working together to contribute to people's lives and to continue our development.
