SECTION 6 Operation

 

Put the plug of power into the socket and turn on the power switch, the air blower 
start working. Activate the BLOWER by turning the FAN SPEED knob clockwise. 
The IONIZATION INDICATOR will illuminate to indicate the presence of ionized 
air.  
Set the air flow as desired by adjusting the FAN SPEED knob. To clean the ion 
emitter points, rotate the POINT CLEANER knob clockwise to the stop 
(approximately one turn) and release. Turn on the lighting switch if need. 
 
The BLOWER OVERHEAD produces an ionized air stream that covers a targeted 
area. The time required to neutralize a static charge on an item in the air stream 
depends on many factors. Two important factors are: distance to ionizer and air 
velocity. Air ions constantly “neutralize” each other. Positive and negative ions are 
statically attracted to each other. When they contact, the charge transfers and the 
ions “recombine”. With high air velocity, the air ions travel further before they 
“recombine”. Setting the fan speed as high as acceptable results in more rapid 
neutralization. For fast neutralizing, the item should be held within 1 to 3 feet from 
the BLOWER.   
 
When using the BLOWER in an electronics assembly area, the ionized air stream 
should cover as much of the work area as possible. Charged items introduced into 
the work area will be neutralized and will remain neutral while in the ionized air 
stream.
