EAO Ltd Burgess Hill – August 2026 – EAO Ltd is proud to launch Sanyo Denki’s new 40 × 20 mm and 40 × 28 mm 9RA series DC Fans, designed to operate as some of the quietest 40mm fans in the industry. Built for low noise and high efficiency, these fans are best suited for compact and high-density equipment such as power supply units, inverters and medical equipment, they are available in 5V ,12V and 24V voltages.
By optimising the frame, the impeller design and the motor efficiency – typical noise reductions of 7dB(A) and power reductions of around 50% have been achieved when compared to existing 109P Series Sanyo Denki fans.
Both fan sizes use reliable, long life dual-ball bearings rated for 60,000 hours at 60°C and a Humiseal protected PCB for moisture resistance and are available with three different fans speeds and for 5, 12 or 24V DC operation
