Wide-Area Static Control

The CHUERA-ST028 is designed for applications where static electricity needs to be controlled across a relatively broad working area.

Its horizontal configuration distributes ionized airflow along the work surface, making it suitable for production benches, assembly lines and other areas where several components may need simultaneous static neutralization.

The specified effective coverage is approximately 600 × 1200 mm.

High-Efficiency Ionization

The blower uses AC high-voltage ionization to generate positive and negative ions.

These ions are carried into the working area through the fan airflow, helping neutralize electrostatic charges on products, components and nearby surfaces.

Under the supplied test conditions, the static decay time is no more than 2 seconds at a 300 mm test distance.

Strong Airflow Output

The ST028 provides an airflow range of approximately 70–120 CFM.

The airflow can be adjusted according to the working distance and application requirements. This allows users to balance air movement with the characteristics of the products being processed.

Ion Balance Indication

An ion balance indicator is provided for checking the operating condition of the ionization system.

The specified ion balance is within ±10V when measured at a 300 mm test distance under the stated conditions.

This provides operators with a convenient reference during routine equipment inspection.

Optional Heating Configuration

The ST028 supports an optional warm-air configuration.

The specified power consumption is 50W without heating and 250W when the heating function is included. This provides an additional configuration choice for environments where heated ionized airflow is required.

Adjustable Installation Angle

The horizontal blower supports angle adjustment, allowing the airflow direction to be positioned toward the intended work zone.

This is useful when the installation position or workstation layout changes between different production processes.

Convenient Ion Needle Maintenance

The equipment can be equipped with a dedicated ion needle cleaning device.

Regular cleaning helps remove accumulated contaminants from the ionizing components and supports stable operation over extended periods.

Practical Protection Design

The ST028 includes grounding protection as part of its electrical safety design.

The unit can be installed in a fixed position above or alongside the working area, depending on the layout of the ESD-controlled environment.

Test Performance

The supplied test data was obtained under conditions including humidity below 60%, test voltage from 1KV to 100V and an ambient temperature of 22°C.

At a test distance of 300 mm, the measured positive static decay time is approximately 1.0 second, while the negative decay time is approximately 0.8 second.

At 600 mm, the corresponding values are approximately 1.9 seconds for positive charge and 1.8 seconds for negative charge.

The measured residual voltage is listed as approximately +7V/-7V at 300 mm and +9V/-9V at 600 mm.

Actual performance may differ according to installation distance, airflow conditions, humidity, material properties and other environmental factors.
