„ Variable DC method
The SJ-F100W/100/010 uses a variable DC method that generates + and - charged air ions from
separate electrode needles, respectively. The generation of + and - ions ensures a stable ion balance
free from fluctuation in the + and - charges.
The SJ-F100W/100/010 also automatically controls the amount of + and - ions generated matched to the
charged state of the target object, degree of dirt on the electrode needles, and other factors. This
enables high-speed and high-precision static elimination suited to installation conditions and conditions
of use.
„ I.C.C. (Ion Current Control) method
This control method calculates the charged level of the target object by sensing the state of ion current
that arises due to the potential between the Static Elimination Blower Unit and GND. Optimum static
elimination matched to the state of the target object can be performed by rapidly supplying the optimum
ions suited to the polarity and charged level of the target object.
„ Fan speed adjustment function
The blast from the Static Elimination Blower Unit is adjusted. This fulfils a vital role
in improving static elimination speed and extends the static elimination area.
