Handheld Static Control

The CHUERA-ST022 is built for applications where static electricity needs to be removed from a specific product, component or work area. Unlike fixed ionizing equipment that covers a defined zone, the handheld gun allows the operator to direct ionized airflow exactly where it is needed.

This makes it practical for workstations involving manual assembly, inspection, cleaning and component handling.

Ionized Air for Dust Removal

The ST022 combines ion generation with compressed-air flow. The airflow helps remove loose particles from the target surface, while the generated ions help neutralize electrostatic charges that can attract dust.

This combination is useful when both static buildup and surface contamination need to be addressed during the same operation.

Comfortable Gun-Style Design

The handheld gun is shaped for direct manual operation. Its trigger-style structure allows the operator to control the airflow while working around individual components or localized areas.

The compact arrangement also makes it easier to move between different work positions without repositioning a fixed ionizer.

Built-In High-Pressure Air Path

The unit incorporates a dedicated high-pressure air passage for delivering airflow through the ionizing nozzle.

The specified working air pressure is 40–70 psi, with an airflow velocity of more than 10 m/s under the stated specifications.

Adjustable Cable Length

The standard high-voltage cable length is 3 m, with customization available according to the supplied product information.

A suitable cable length can help accommodate different workstation layouts and installation distances between the power unit and handheld gun.

Low Current Operation

The ST022 operates at a specified working voltage of 4600V with a consumption current of approximately 200 μA.

The low-current operating design is intended for ion generation while keeping the electrical consumption of the ionizing section relatively limited.

Stable Ion Balance

The specified ion balance is 0V ±35V.

Maintaining a balanced ion output is important for static-control applications because the purpose is to neutralize existing charge rather than introduce a significant new charge onto the target.

Quick Static Decay

Under the supplied test conditions, the ST022 achieved a static decay time of 0.8 seconds at a test distance of 150 mm.

The referenced test conditions include an ambient temperature of 22°C, humidity below 65% RH, and a test voltage of ±1 kV to ±10 kV.

Actual performance can vary with distance, airflow conditions, target material, environmental humidity and installation setup.

Operating Considerations

For effective use, the ionizing nozzle should be directed toward the surface requiring treatment while maintaining an appropriate working distance.

Compressed-air pressure should remain within the specified operating range. The actual static neutralization result depends on the distance between the nozzle and target, environmental conditions and the characteristics of the material being treated.

Regular cleaning of the ionizing nozzle can also help maintain consistent airflow and ionization performance.
