AC Infinity CLOUDLIFT S12 (12") – Clip-On Fan Duct

This is a 3D-printed fan duct designed specifically for the 12" AC Infinity CLOUDLIFT S12 Industrial Wall Fan. 

The duct clips directly onto the fan's existing wire safety cage and requires no modification to the fan itself.

The duct allows the fan to be mounted externally to a filter box, providing clearance for fasteners and mounting clips while improving airflow direction. By reducing air spill around the fan perimeter, the duct forces more air through the filters, improving overall system efficiency.

The design prints as four identical parts that snap together to form a complete duct. Once assembled, the duct securely clips onto the fan’s factory wire guard, making installation and removal quick and tool-free.
