A Modular Fan Array of a 2&#xd7;2 array of small fan modules provides many advantages over the replacement of duty of a solitary large fan, including some of the following advantages: &#x2014;the combined flowrate capacity of the Fan Array can be sized equal to or in excess of the 100% flowrate capacity of the large fan, however a turndown limit of 50% will result in the Fan Array only having a turndown limit of 12.5%. There is a redundancy fan modules. With one going OFFLINE the other three can provide some measure of ventilation, while with the large fan going OFFLINE, ventilation is disable completely.
