Advantages of UniFlow CAV By-Pass Fume Hoods

1. Important: by incorporating Sash Management 1-2-3, you are
    saving 50% on overall energy costs, and providing the best
    possible user protection & safety.
  6. The Sash Stop is designed for user protection and CFM
     reduction. Allows sash to open to a maximum of half open,
     providing up to 50% energy savings.
2. Recommended that hoods be used with sash 1/2 open with
     face velocity of 80-100 FPM. Sash stop located at 1/2 open
     position. With upper sash raised to the 1/2 open position the
     supply air CFM & static pressure are as noted.
  7. Sash at full open is primarily designed for set-up of equipment
    and maintenance. Fume hood users should wear personal
    safety protection equipment, consult Lab Safety Officer.
3. Sash in full open position should be for setup of apparatus &
    maintenance service only. If design opening is at 1/2 open at
    100 FPM, face velocity at full open would be approximately 50
     FPM. The recommended face velocity for efficiency & safety
     is 80-100 FPM. Lower face velocity may compromise user     safety.

  8. HEMCO recommends 10-12 room air changes per hour for the
    health & safety of personnel. Example 10’ X 20’ room 10’ high
    receiving 10 room air changes per hour requires 350 CFM air
    flow through the lab.
4. When hood is not in use, keep sash in closed position.

5. Sash stops are standard on U.L. Classified Fume Hoods.
    UniFlow SE, LE and CE AirStream fume hoods
  9. At an average utility rate of $7.00 per CFM, a typical annual
    savings on a 4’ fume hood would be $2705.00 and on a 6’ fume
    hood $4067.00, by using Sash Management 1-2-3., Sash Stop
    at 50% open.

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.

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.
