| The System 2 Kit consists of two ( four in the 2+2) 4.7” square fans, drive electronics, temperature sensing element (thermistor), grilles, and power supply. While its operation is identical to that of the original System 2, the kit offers greater flexibility because the individual fans can be separately mounted in a variety of configurations.
Whether its a System 2 or a 2+2, one or two of the fans can be used to exhaust heated air, while the other(s) can be used as intake devices.
If desired, all fans can be used as intake devices with a passive exhaust opening, or as exhaust devices with a passive intake opening.
