Your workshop runs cleaner when air moves out fast. This 4-inch box fan adapter bridges the gap between your box fan and duct pipe, so you can pull dust, laser fumes, or exhaust straight outside.

You get design variations for round pipes, standard flanges, and different spout types. Pick the version that matches your setup. Print it on demand, and it arrives ready to install. No waste, no extra parts gathering dust on your shelf.

Works with full spectrum lasers, dust collectors, and general workshop ventilation. Snap it on, tape it down, and breathe easier while you work.
