Originally designed for cooling CPUs, Orion's OD70 series fans optimize performance in a slightly smaller package for a wide range of enclosure applications. The 70 mm, tubeaxial DC fans deliver high airflows ranging from 19 CFM up to 60 CFM with low noise levels of 49.5 dB down to 29.0 dB.
The OD70 family is offered in 12 VDC and 24 VDC versions, can be built in alternate speeds, and can be ordered with optional IP55 protection and special functions including thermal control, alarm, tachometer, and pulse-width modulation (PWM). The UL94V-0 plastic frame and impeller is designed for a long operational life of 70,000 hours at 40°C.
密封式滑动轴承风扇
Orion Fans 的密封式滑动轴承系列通过采用获得的独特密封套筒技术来延长风扇使用寿命,使其预期寿命非常接近球轴承风扇。这种技术利用金属箔来保留润滑油,当润滑油离开滑动轴承时将其捕获并使其再流回风扇。
