1) Air enters at “A” in an even horizontal laminar fl ow.
2) Contaminated air enters “B” where particulate is removed via electrostatic
pre-fi ltration and HEPA fi ltration.
3) Particulate free air moves upward to “C” where it enters the HEPASafe™
fi ltration area. This fi ltration is only challenged with particulate during
primary fi lter changeout.
4) Particulate free air then passes into “D”, the deep carbon fi lter bed, where
dangerous chemical fumes and vapors are removed.
5) Clean air is then exhausted at “E” for return to the laboratory.
