This unit boasts superior ionization performance nearly twice that of conventional ionizers, which is enabled through the use of twice as many discharging electrode needles as conventional units (eight instead of four) and a high air-capacity fan.
KD-750B ionization performance
The original fan guard enables the widest-ever ionization area. When installed as in the diagram below, for instance, ionization can be performed from three IC trays.
KD-750B ionization performance (overhead installation)
The fan comes in the smallest size for a 120 x 120 unit, allowing the ionizer to be installed on a bench or in a manufacturing device while requiring little space.
The stainless steel fan guard is capable of shielding the electric field, while use of an antistatic resin for the body permits installation in an EPA (ESD protected area).
Use of twice as many discharging electrode needles as conventional units and high efficiency ion generation reduce performance degradation, enabling stable, long-term operation. This results in a significant reduction in the frequency of maintenance.
The KD-750BB comes equipped with a cleaning brush that allows easy cleaning of the discharging electrode needles simply by turning the front knob. This significantly reduces maintenance.
The addition of the cleaning brush in no way affects the unit’s ionization performance, ensuring that it eliminates static as quickly as previous versions.
The cleaning brush is compatible with the KD-750B’s fan guard. KD-750B currently in use can be easily equipped with the cleaning brush.
The front display panel allows easy confirmation of the ionizer’s operating status. The unit is equipped with a lamp that signals when cleaning is needed. This lamp was featured in previous models and well received by users. Moreover, the unit also has a fan monitor lamp that informs of fan failure.
The terminal block on the rear side allows easy connections for power input and output and alarm output. This means that the ionizer can be easily interlocked with all types of manufacturing devices, so that signals indicating performance degradation due to poor maintenance or loss of ionization effect from fan failure are immediately transmitted to the device in which the ionizer is used.
The unique design ensures the widest possible variable range of air volume, which permits the fastest-ever ionization from microelectronic devices at an extremely weak airflow.
