EAO Ltd, Burgess Hill, 04 August 2025 – EAO Ltd is proud to announce the launch of the new Sanyo Denki San Ace 80 9CRHA Series, an advanced line of 80 × 80 × 80 mm counter rotating DC fans engineered to deliver exceptionally high static pressure in compact form factors. Designed for demanding thermal environments, the 9CRHA Series combines speed, control and durability for reliable performance in systems such as telecoms equipment, power modules and high-density electronic enclosures.
Among the highlights of the new range are the 9CRHA0812P8J001 and 9CRHA0848P8J001 models, which incorporate a pulse sensor with PWM control to enable precision fan speed management. These fans deliver a maximum static pressure of 2700 Pa (10.8 inchH₂O)—a 38% increase compared to the previous generation (San Ace 80 9CRH type)—while maintaining a maximum airflow of 5.65 m³/min (199 CFM).
