AirStack X – Triple Box Fan Tower

Turn three standard 20” box fans into the ultimate full-body cooling system.

AirStack X is a 3D printable bracket system designed to vertically stack three Lasko-style 20” box fans into one powerful airflow tower. Originally designed for use inside our production facility at Rock Hill Screen Printing, AirStack X delivers serious cooling performance for hot shops, garages, patios, gyms, warehouses, campsites, and more.

Once assembled, all three fans plug into a single power strip so you can control the entire tower with one switch. Simple. Powerful. Effective.

The vertical stacked design creates full-body airflow from head to toe while saving floor space compared to spreading multiple fans around a room.

Why I Made It

Traditional box fans work great, but one fan only cools part of your body. AirStack X was designed to create maximum airflow coverage using affordable fans most people already own.

We use these daily in our screen-printing shop to help keep printers cool during long production runs in the summer heat.
