Fans for server applications

25th June 2018


EAO has introduced a new series of small, low voltage blower fans that deliver a static pressure of up to 1950P and an airflow of up to 111 metres cubed/hour at a rated speed of 8200 rpm.

 
Developed by Sanyo Denki, San Ace 9BMC blower fans measure just 97mm by 33mm but delivers the cooling performance and low noise requirements demanded by high-density equipment such as servers, PSUs, fuel cells and air-con units. In a typical higher performance cooling system, the new fans provide 50% higher static pressure and 15% higher airflow than the Sanyo Denki 9BMB family. Alternatively, whilst running by at a P-Q point equivalent to a competitors’ products, the new blower fan consumed 20% less power and 3dB(A) less SPL (sound pressure level).
 
The new San Ace 9BMC blower fans are available in 12 and 24VDC variants. They feature optional pulse sensors (tacho) and pulse width modulation (PWM) control, which facilitates external control of fan speed. Engineered with dual ball bearings the new fans provide reliability figures of 70,000 hours MTBF at 40ºC (40,000 hour at 60ºC).
 
The 9BMC blower fan is part of range of Sanyo Denki, San Ace brand DC blower fans that also includes models with frame widths of 52, 76, 97, 120, 127 and 160mm.
