High-speed Ionization
A Unique Structure Provides a Uniform Airflow
The newly developed airflow control system (AFCS) structure optimally controls the airflow of the fan
to efficiently carry the discharged ions to the target workpiece. This gives the ZJ-FA20 the highest
ionization performance in its class.
Even with the airflow at a low setting, ionization is completed in approximately 2 seconds. Small, light
workpieces are not blown away by the airflow, and static electricity is effectively neutralized.
Airflow Control System (AFCS)
Conventional
ZJ-FA20
The front louvers and
internal structure keep
the airflow uniform.
The airflow is dispersed,
lowering efficiency.

More Versatile Use
Long-term Ionization Performance
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.
Clean and Easy Maintenance
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.

A Variety of Installation Possibilities
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.
