What are the 3 types of media used Active carbon, chemically treated carbon,
in contaminate control potassium permanganate
What is residence time? the time it takes air to cross a distance equal to
the thickness of the filter without accounting for
the resistance of the media through which it
travels
What are the variations of the clean the air required by the process, blanket the
contamination control principle product with cleaned air, offer enough air flow to
move contaminated air away from the product
, What is removal efficiency The fraction of the contaminate that once in
contact with the media is removed by either
physical or chemical means
What is Capacity The amount the media is capable of removing -
this determines the life of the filter

62.1/62.2 specific minimum ventilation rates IAQ which will
be acceptable to humans and are intended to
avoid adverse health effects
How many classifications of air is 4
there?
What are the IAQ testing Particulate contaminants, Gas phase, systems
applications integrity, comfort parameters
What are the control strategies Filtration, source removal, Dilution
Min demonstrated overspray filter 98%
eff must be at least
What is the min eff for a Super 99.9999% on MPPS
