Room air is pulled into SecureDry™ through
electrostatically charged pre-filtration at "A". This pre-filtration is
designed to remove gross particulate and fibers (potential
cross-contamination).
Once room air is inside SecureDry™, it
circulates around the wet evidence at ″B″ before entering a three-stage
filtration process.
The exhaust air passes through an
electrostatically charged pre-filter at ″C″. This pre-filter captures
any trace evidence present in the airstream, and should be removed
between cases for laboratory examination.
Air then passes into the HEPA filter at ″D″. The HEPA filter captures potentially harmful biological material.
Air passes through the gas phase carbon
filter at ″E″ before exiting the chamber. The gas phase carbon filter
prevents putrid odors from escaping into the laboratory space.
