FANWALL® Smart Cube

Integrated Inverter Control Solution for New Construction and Retrofit Applications

In the FANWALL Smart Cube configuration, active control components are factory-installed and wired at the FANWALL Cube for quick connection to power at the control panel. This eliminates labor and time to field-install power wiring, pressure tubing, and communications cabling in the air handler, and dramatically reduces the size and complexity of the unit control panel. It is especially ideal for fan retrofit applications where timelines are tight.
