OK, so it took showing up at 7am Monday morning with a “Box ‘O Joe,” a dozen assorted donuts, and a lot of energy, but the hood is now done, and done right. It’s not perfect, but better than anything else I’ve seen on a food truck.
We got an “inline” fan, which means it fits right in the vent and pulls the air through the blades. The new fan is very quiet, and we mounted it above the hood, so the air flow is much more smooth and less noisy. The fan is rated at 600 CFM, which means cubic feet per minute. A little less than a restaurant might be, but not too bad.
