Gas Detection/Filter Monitor
1. Air enters at "A" in an even horizontal laminar manner.
2. Contaminated air enters "B" where particulate is removed via electrostatic prefiltration and HEPA filtration.
3. Particulate-free air moves upward to "C" where it enters the Saf-T-Zone filtration area.
4. Particulate-free air then passes into "D", the optional carbon filtration bed, where dangerous chemical fumes and vapors are removed.
5. Clean air is then exhausted at "E" for return to the laboratory.
