When the wind chassis fan selection purposes, consider the piping system leakage losses calculation error, and the actual amount of wind fans, the negative effect of pressure variation of wind chassis, the general air volume of 1.05 to 1.1, pressure of 1.10 to 1.15 safety factor. But do not use too much, in order to prevent long-term fans run at low efficiency area.
