The company is committed to supplying the widest selection of quality axial fans and blowers, which includes DC brushless fans, micro DC blowers, CPU coolers, graphic card coolers and AC fans. Sunon manufactures some of the industries smallest, thinnest and most power efficient fans and blowers in sizes ranging from 0.315 inches (8mm) to 10 inches (250mm) in outside diameter and from 0.157 inches (4mm) to 1.5 inches (38mm) in thickness. More than 700 different models are available to customers.

Sunon has amassed a rich portfolio of over 621 patents. The company focuses a significant amount of its resources each year into research and development activities. Among the many innovations resulting from its efforts are Sunon's unique single-phase full wave coil winding design, which allows hub sizes to be reduced significantly. This design not only extends fan blade size to increase torque, airflow and heat dissipation, but also results in the ability to create the world's smallest, thinnest and lightest brushless DC fan. Sunon's new innovative vapo bearing technology and magnetic system design eliminate wobbling, reduce bearing wear, offer exceptionally quiet performance and increase fan life at a cost that is no more than is typical with ordinary fans. Both technologies are patented and include state-of-the-art advances in bearing surface materials and impeller stabilization.
