Chapter 4: High Performance Features and Safety

3.Upper Dilution Air Supply provides bypass air from above the work area. This feature constantly bathes the inside of the sash with clean air and reduces powders, particulate materials and chemical fumes along the sash plane, near the critical breathing zone. Five to seven percent of the required air volume is introduced through the upper dilution air supply. The upper dilution air supply also reduces stagnant pockets of air in the upper interior. See Figure 4-2.

4.Zoned Rear Perforated Baffle directs horizontal laminar air streams to the three-zoned sections of the perforated baffle. The three-zoned sections have increasingly more open area at the bottom that help form laminar airflow. This minimizes the potential for air to roll forward preventing contaminants from moving toward the sash opening. The majority of contaminants are highly diluted, captured and removed on the first pass through the enclosure. See Figures 4-1 and 4-2.

5.Side-Entry Air Foils allow turbulence-free air to enter the enclosure from the sides and allow clean air to sweep the interior walls of the enclosure. See Figures 4-1 and 4-2.

6.Ergonomic Slope of 10 degrees provides maximum visibility, and comfort reduces glare, thereby minimizing operator fatigue. See Figure 4-1.

7.Internal Depth of 23" provides necessary depth to support modern balances and other auxiliary equipment without extending outside the enclosure or resting on the lower air foil. See Figure 4-1

8.Safety Glass Sash with Spring-Loaded Latch has a wiping seal to contain contaminants and features a spring- loaded latch to secure sash open for loading and cleaning. The sash must be down for normal operation. See Figure 4-1.

9.Utility Ports with Iris allows electrical cords and data cords to pass through the back of enclosure without leaving a large hole for contaminants to escape. The enclosure ships with solid plugs. Iris plugs are included with the User’s Manual. See Figure 4-1 and 4-2.

10.Accessory Guardian Airflow Monitor or Guardian™ 1000 Digital Airflow Monitor continuously monitors airflow. An audio/visual alarm alerts the user to low airflow conditions. The Guardian 1000 Digital Airflow
