Important Notice: This item is final sale and non-returnable.
The 4WC unit has the same 4 - 92mm fans as the 4FN unit but is pre-configured with the optional Cover Plate installed on the housing and the airflow of the fans is reversed. The unit in its factory configuration is designed to be used in applications that require all of the exhaust to be directed out the front of the unit. Depending upon how the unit is positioned with the fans exposed on the top of the unit or the bottom it can be used to pull air from below or above and direct it out the front of the unit. By reversing the factory airflow configuration the unit can also be configured to pull air in from the front of the unit and direct it upwards or downwards.
