My forced-air paper dryer is 22 inches square and 11 inches tall, made of lightweight birch and poplar. It dries sheets up to 13×19 inches, under restraint, in 6-12 hours. It requires 20 pieces of double-thick corrugated, and 40 pieces each of fiberglass mesh and blotters.
The box and lid weigh about 12 pounds. The dual 5-inch fans are quiet (<29dBA) yet relatively powerful (89CFM). The 12-volt fans operate on either 120V or 240V with the included adapter.
