1.DC and EC fan motors efficiency up to 70%,much more energy saving than AC motor fans ;
2.Quiter operating which can be down to 19 dBA ;
3.Suitable for extreme temperature environments : - 25℃ ~ +60℃
4.EC and DC Cross flow fans provides more variable ,unenen air flow ,minimal electromagnetic interference than ac cross flow fan ;
5.Lower voltage operating - integrated PCB control system ( DC cross flow fan and EC cross flow fans)
6.DC / EC motors provides more speed options for customers ,such as 0-10V / PWM and even RS485 protocol which is built-in PCB borad .
