Low voltage blower fans target high-density equipment
A series of small, low voltage blower fans that deliver a static pressure of 1950P (max.) and an airflow of 111m3 /hour (max.) at a rated speed of 8200 rpm are available from EAO. Developed by Sanyo Denki, the San Ace 9BMC blower fan measures 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 20% higher static pressure and 8% higher airflow that competitive products, and 50% higher static pressure and 15% higher airflow than its predecessor, the Sanyo Denki 9BMB.
Alternatively, whilst running by at a P-Q point equivalent to competitors’ products, the new blower fan consumed 20% less power and reduce the SPL by 3dB(A).
The San Ace 9BMC blower fans are available in 12 and 24VDC variants. They feature optional pulse sensors (tacho) and 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 40 oC (40,000 hour at 60 oC), ensuring trouble-free long-term operation.
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.
