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 construction 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.
