Most all of us will have traveled either by plane,
train or bus in our lifetime and, in so doing, spent
time in the terminal waiting area. Indoor airport,
train and bus terminals and waiting areas are
ventilated to provide breathing air for human
comfort and health. The large amounts of outside
air drawn into these terminals can cause the air
to be heavily polluted. The increased levels of air
pollution present in these areas affect passenger
comfort, satisfaction and sometimes even health.
In most cases the indoor air pollution in these
areas consists of both particulates (solids) and
molecular contaminants (gases) which can affect
the respiratory system through the simple act
of breathing. Utilization of advanced filtration
technologies allow for effective removal of
molecular and particulate pollution known to be
of concern.
Gaseous/Molecular Pollution
Jet airplanes as well as idling buses, trucks, taxis and other automobiles produce several gaseous pollutants including nitrogen
oxide
(NOX), nitrogen dioxide, sulfur dioxide (SOX) aldehydes and aromatic hydrocarbons (PAH). Other sources of gaseous pollutants include
cigarette smoke, hydrocarbons produced by cleaning agents, etc., and fumes/odors from food facilities and/or human beings.
Particulate Pollution Both jet and diesel engines (buses, trucks, etc.) release fine particulates in their exhaust. Particulate pollution can also consist of dust, road dirt, ash, airborne fungal spores, etc.
Air Filters from AFC...
•
remove gaseous pollutants from the air stream thus eliminating harsh/harmful odors and contaminants
•
help protect visitors from re-circulated air that has been contaminated or entered through unfiltered openings
•
reduce indoor levels of particulate pollutants inside the building
•
substantially improve air quality conditions in the building
