Company information
Our company was established as Sanwa Shiki Ventilator Co., Ltd. after separating from the manufacturing division of Sanwa Industrial Co., Ltd. Initially, we focused on the manufacturing and sales of rotary and fixed ventilators, fireproof hoods, and other products. We contributed to the development of local industries and built a solid foundation based on the trust we received from related parties. Currently, we are concentrating on the development of pressure-resistant explosion-proof ventilation fans 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, we aim to advance our research and development of ventilators, as well as hatches for industrial and residential use. We hope to work together as a united team to contribute to people's lives and continue to grow.
