Ionization can be used to treat air that has a high level of VOCs. <br /> VOC Effects <br /> Ion <br /> 0 0 0 000 0 0 00 00 0 0 0 00 <br /> 0 0 0 00 00 00 00 00000• 0 0 0 0p0 00 0 0 0 0 <br /> °0 0 0 o 0o pe0o0 000 0 0 0 0 <br /> 0 0 ° 0 N"Hj-W J r� �' o <br /> ° 0po°0o a°oo ♦ °0© � °0000 ; o d 0 <br /> 00090 00 000 0 • 0 D0 O * oo 0 00 0� 00a D <br /> 0 ° ° o 00000 0 00 ° 0 0 040 <br /> 000 <br /> D a p 0 0 O o D 0 0 0 00 0 0 0 o 0 Muur wpw Him o 0 0 <br /> 0 0 0�00 0 0 0 00 0 0 Qo00o O 00000 a 0 <br /> Ions created in Ammonia(NH) Free floating positive The gases regroup to <br /> forced airstream.

Through this <br /> process the positive and negative ions are attracted to particles and these positive and negative ions attract <br /> fine particles to each. This causes fine particles to be enlarged making it harder for them to stay suspended in <br /> the air. When ionization is installed upstream of air filters, it allows them to capture these agglomerated <br /> particles that might have otherwise passed through the filter. <br /> Airborne Particle Effects <br /> ion <br /> ion 9 ion <br /> q X0 <br /> ion ArrbnnN ton Agglomerated <br /> rw& Particles <br /> ion 6 '*ion <br /> ion <br /> ■ Once the ions attach to the particle,the <br /> particle grows larger by attracting nearby <br /> particles of the opposite polarity,thereby <br /> increasing the filtration effectiveness. <br /> Page 5 of 10 <br />
