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).   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.
Traditional Fume Hoods   1. Fully Assembled Fume Hoods   UniFlow Fume Hoods
 

Traditional Fume Hood 60” wide Constructed of formed painted sheet metal panels & held together with sheet metal fasteners & brackets. Chemical resistant interior liner panels with sharp corners sealed with caulking.

Customer Comments:
Hoods, based on the nature of the products we analyze (sulfur chlorides, sulfuric acids, oleums), last about two to three years. At the end of three years, the chemicals have corroded both the exterior steel panels and the internal steel frame work of the metal hoods. We replaced them eight years ago with HEMCO UniFlow fiberglass fume hoods the installation was easier and we have had no repairs since then. We are building a new facility, and we plan to install HEMCO hoods. Steve Mixon, Chief Chemist

Chemical Resistance Chart

UniFlow Fume Hoods are constructed of white composite Fiberglass Reinforced Polyester (FRP) material. FRP is an excellent general purpose material for fume hood construction.

• Superstructure features unitized dual wall constuction with integral one piece fume chamber for total chemical resistance, non-sparking construction, for hazardous locations.

• UniFlow HiPel FRP Composite construction is UL 1805 Classified for Laboratory Fume hoods and cabinets.

• HEMCO HiPel FRP composite conform to NFPA 45 for products used in laboratories.

• To provide for the best airflow performance through the fume chamber, any heat generating equipment should be elevated 2" to 3" above work surface and 4" to 6" away from side walls and rear baffle system, and at least 6" away from the sash opening.

Chemical resistance of HEMCO’s most widely used FRP composite construction, and other liner material options.
