Wide Coverage for Production Areas

The CHUERA ST series is designed for situations where a compact tabletop ionizer is not sufficient to cover the required working area.

The suspended structure allows the blower to be positioned above the workstation, helping distribute ionized airflow across a wider zone. Three configurations are available, allowing users to select a suitable model according to the size of the target area.

Three Fan Configurations

The series includes three models with different fan arrangements.

ST-002 uses a dual-fan configuration with an effective range of approximately 400 × 600 mm and a rated power of 20W.

ST-003 uses three fans and provides an effective range of approximately 400 × 800 mm, with a rated power of 30W.

ST-004 uses four fans for an effective range of approximately 400 × 1000 mm and a rated power of 40W.

The three models share the same basic operating concept while offering different coverage capacities.

Continuous Static Neutralization

The equipment generates positive and negative ions and delivers them into the working area through the built-in fans.

This ionized airflow helps neutralize electrostatic charges that may accumulate on components, products, fixtures and surrounding surfaces.

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

Model-Based Airflow Capacity

The airflow capacity varies according to the selected model.

The ST-002 provides approximately 80–110 CFM, while the ST-003 and ST-004 provide approximately 120–330 CFM.

This range allows the equipment to be selected according to the required working width and airflow demand.

Ion Balance Control

The series provides an ion balance specification of within ±10V at a 300 mm test distance under the stated testing conditions.

Maintaining suitable ion balance helps reduce the risk of introducing an undesirable charge while the ionizer is operating.

Built for Suspended Installation

The ST series is designed around an overhead mounting concept.

The standard hanging mounting accessories can be used to secure the equipment above the work area. This arrangement leaves more bench space available for products, tools and production equipment.

It can also be useful when static-sensitive components need to be treated across a continuous workstation rather than at a single fixed point.

Low-Ozone Operation

The specified ozone concentration differs by model.

The ST-002 is rated at no more than 0.01 ppm, the ST-003 at no more than 0.02 ppm and the ST-004 at no more than 0.03 ppm.

These values are based on the supplied product specifications and should be considered together with the actual installation environment.

Practical Maintenance Structure

The fan assemblies are designed for routine cleaning and maintenance.

Keeping the fan guards, airflow passages and ionizing components clean can help maintain normal airflow and static neutralization performance during long-term operation.

The suspended mounting arrangement also provides a relatively clear working surface beneath the equipment.

Stable Operating Range

The series is specified for operation between 0°C and 60°C, with working humidity of no more than 90%.

The listed noise level is approximately 40–55 dB.

These specifications make the series suitable for a variety of indoor production environments where static control is required.

Electrical Specifications

The ST-002, ST-003 and ST-004 support 220V/50Hz or 110V/60Hz input power.

Rated power is 20W for ST-002, 30W for ST-003 and 40W for ST-004.

The specified static decay performance and ion balance values are based on the test conditions provided by the manufacturer.

Physical Configurations

ST-002: Approximately L600 × W170 × H125 mm, weight approximately 6.4 kg.

ST-003: Approximately L1100 × W170 × H125 mm, weight approximately 8.7 kg.

ST-004: Approximately L1600 × W170 × H125 mm, weight approximately 10.2 kg.

The increasing housing length corresponds to the different fan configurations and coverage ranges.

Application Scenarios

The ST series can be used in production areas where static electricity needs to be controlled over a relatively broad zone.

Typical applications include:

• Electronics assembly lines

• PCB and SMT workstations

• Semiconductor production

• Precision component handling

• Optical assembly

• ESD inspection areas

• Plastic component processing

• Automated production lines

• Laboratory work areas

• Static-sensitive packaging and handling

Choosing the Appropriate Model

The model should be selected according to the required coverage area.

For a working area of approximately 400 × 600 mm, the ST-002 provides the corresponding configuration.

For approximately 400 × 800 mm, the ST-003 offers a wider three-fan arrangement.

For approximately 400 × 1000 mm, the ST-004 provides the broadest configuration in this series.

Actual selection should also consider installation height, airflow requirements and the characteristics of the products being processed.

Installation Considerations

For best results, the ionized airflow should be directed toward the area where static control is required.

The installation height and surrounding equipment can influence ion distribution and static decay performance. After installation, the actual working conditions should be checked to confirm that the selected position provides suitable coverage.

The supplied hanging brackets should be securely installed before placing the blower into regular operation.
