1. "Micro Cooling Fan" FANb Although the amount of wind and static pressure are more FANa high, but customers should be based on the best choice OPa; non only fan the maximum air flow and maximum static pressure as the selection basis.
2. The system impedance design quality also select one of the key "Micro Cooling Fan" of; R1 line impedance optimal system design, R2-based system impedance is higher, lower R3; To improve the system impedance should be designed from the system inlet and outlet the size of the adjustment, position adjustment in the emissions system components, etc., then you can adjust it via wind tunnel testing and validation of the best system impedance.
3. Compare the "Micro Cooling Fan" FANa and FANb can be learned and fan motor torque, frame design features of the more FANb FANa good.
