A built-in ion balance sensor constantly senses the ion condition, and a 

variable DC system maintains the optimal ion balance at all times. This 

provides a long-term, stable balance for reliable ionization.

The ion balance is sensed and the voltage applied to the discharger 

electrodes is varied to adjust the ion output.

Long-term Ionization Performance

The ZJ-FA20 features a fully opening front cover. 

Removing it allows neat and thorough cleaning, 

without spreading dust and other particles around. 

The discharger electrodes can also be replaced for 

long-term operation. LED lamps show the 

ion-generating condition and indicate when 

cleaning is required.

In addition to table-top or bench-top installation, the ZJ-FA20 can be easily 

mounted to an aluminum pipe. The angle can also be freely adjusted using the 

angle-adjustment knob and oblong stand.
