DIY Box Fan Tower: Build a Mobile Workshop Fan Stand
Keeping air moving in your woodworking shop can make a big difference, especially during the hot summer months. A box fan is an inexpensive way to improve air circulation, but finding a convenient place to put one isn't always easy.
This shop-made box fan tower solves that problem by stacking two inexpensive box fans in a sturdy, mobile plywood frame. With locking casters and a convenient power strip, you can roll the fans where they're needed and adjust the airflow to suit your workspace.
Build a Simple Plywood Frame for Two Box Fans
The tower starts with a basic plywood frame sized to fit a pair of box fans. There's no complicated joinery involved. The corners are assembled with glue and screws, making this a quick and practical shop project.
Before cutting the plywood, measure your fans carefully. Box fan dimensions vary, and some models have controls on the sides rather than the front. Choosing fans with front-mounted controls makes it easier to build a close-fitting frame while keeping the switches accessible.

Add Brackets to Keep the Fans Secure
Once the frame is assembled, add plywood corner blocks to reinforce the structure and prevent racking.
These blocks also extend slightly over the edges of the fans, helping keep them securely positioned inside the frame.
The simple retaining brackets make it easy to build a sturdy fan tower without complicated hardware.

Make the Fan Tower Mobile with Locking Casters
Attach the plywood frame to an oversized plywood base for added stability. A simple base bracket helps secure the upright frame to the platform.
Next, install a set of casters underneath the base. Using at least two locking casters allows you to roll the fan tower around the shop and secure it in position when needed.
The mobile design makes it easy to direct airflow toward your workbench, assembly area, or another part of the workshop.
Add Convenient Power Controls
For the finishing touch, mount a suitable power strip to the side of the tower.
This provides a convenient location to plug in both fans, and a single switch can turn them on or off together.
Be sure the power strip is rated for the combined electrical load of the fans, and keep the cords clear of the casters and moving parts.

Improve Air Circulation in Your Woodworking Shop
This simple box fan tower is an inexpensive way to make your workshop more comfortable. The stacked fans provide adjustable airflow, while the rolling base makes the entire setup easy to reposition.
It's a useful project for circulating air during warm weather or moving fresh air through the shop when conditions allow.
For finishing operations involving hazardous vapors or combustible solvents, ordinary box fans aren't a substitute for properly designed ventilation equipment. Always follow the finish manufacturer's ventilation and ignition-source precautions.
With a few pieces of plywood, two box fans, and some basic hardware, you can build a versatile workshop accessory that helps keep the air moving wherever you're working.
