1. Rated voltage: is "Micro Cooling Fan" under rated operating voltage, the common voltage DC fans in general for 5V, 12V, 24V, 48V, and other specifications.
2. Fan Size: mainly refers to the size of the fan, a fan outside the general length and the thickness of the product, in units of mm. Fan Specifications Model name often size number, for example: DC8025, 8025 which represents the size of the product specifications.
3. Fan Speed: "Micro Cooling Fan" degree rotation speed, the unit is rpm (revolutions per minute), which is a more important parameter fan, high-speed winds of show can bring, manufacturers often standardized products, divided an ultra-high (U), high (H), medium (M), low (L) and other speed products, for the user to choose according to their own situation.
4. The amount of wind: a quantitative indicators to measure the ability of a fan, in units of cubic feet per minute (CFM).
5. Pressure: Peugeot Chi "Micro Cooling Fan" ability to overcome the drag of the wind flow, the index directly affect ventilation or cooling effect, in units of mm-H2O.
6. Noise level: It is an important parameter, although nothing to do with ventilation effect, but the use of different environments on the demanding, the unit is dBA (decibels).
