Traditional Fume Hoods vs UniFlow Fume Hoods Innovation is the Difference Between the Same Perspective and an Entirely New one. The 1925 Ford Tri-motor, featured all metal construction, no wood. Its fuselage and wings were constructed of corrugated sheet metal, for strength. These aircraft were well-designed, and reliable (for the era). Traditional Fume Hoods The Boeing 787 Dreamliner features aerodynamic composite construction. Composites have a higher strength to weight ratio, which helps to make the 787 a lighter more energy efficient aircraft. 1. Fully Assembled Fume Hoods UniFlow Fume Hoods...
