Product Overview

The CHUERA-ST026 is developed for situations where static electricity needs to be controlled directly at the workpiece. Its handheld form allows operators to move the ionizing airflow around components, assemblies and work surfaces without installing a large fixed system.

High-frequency electrical discharge generates ions at the nozzle, while clean compressed air carries the ionized airflow toward the target. This operating method supports quick static decay and can also assist with removing lightweight particles from treated surfaces.

Compact Handheld Construction

The gun-shaped housing is designed for manual operation. Its relatively light structure, with a net weight of approximately 0.4 kg, makes it suitable for repeated use at individual workstations.

The 100–400 mm recommended working distance provides flexibility when treating different products or surface areas.

High-Frequency Ion Generation

The ST026 uses a high-frequency discharge method to generate ions. According to the supplied test data, the device can achieve a neutralization time of ≤1.0 second at a distance of 150 mm under the specified test conditions.

The ion balance is specified at ≤±15V, helping maintain a relatively balanced ion output during operation.

Compressed-Air Assisted Operation

The ST026 works with clean compressed air and supports an operating air pressure range of 0.3–0.7 MPa.

The specified air consumption is approximately 5 m³/h at 0.5 MPa. This airflow carries the generated ions toward the target area while supporting surface dust removal.

Clear Status Indication

Power and alarm indicator lights are provided on the unit. These indicators allow operators to check the operating condition directly during use and identify abnormal conditions without relying on a separate monitoring device.

Flexible Power Arrangement

The specified operating voltage is DC24V. The product information also indicates an external power supply arrangement, allowing the unit to be integrated into suitable workstation power configurations.

Practical Static Control

The ST026 is intended for targeted ESD control rather than broad-area room ionization. Operators can position the nozzle according to the shape, size and location of the workpiece.

This makes the unit suitable for production steps where static buildup may occur intermittently or only on selected surfaces.

FAQ

What is the CHUERA-ST026 designed to do?

It is designed to neutralize static electricity at targeted work areas while delivering ionized compressed air.

Is the ST026 suitable for handheld operation?

Yes. Its compact gun-style construction is intended for direct manual use around individual components and workpieces.

What power supply does the ST026 use?

The specified operating voltage is DC24V.

What compressed air pressure is required?

The specified working air pressure is 0.3–0.7 MPa.

What type of air should be used?

The product is specified for use with clean compressed air.

How long is the high-voltage cable?

The supplied specification lists a 3 m high-voltage cable.

What is the recommended working distance?

The specified working distance is 100–400 mm, while the supplied test data uses a 150 mm distance.

How much air does the unit consume?

Air consumption is approximately 5 m³/h when operated at 0.5 MPa.

What is the operating temperature range?

The specified operating temperature is 0–50°C.

Can the ST026 help with dust removal?

Yes. Its compressed-air output can assist in moving lightweight particles away from treated surfaces while the ionization process reduces electrostatic attraction.

What is the difference between static decay time and ion balance?

Static decay time describes how quickly an existing charge is reduced, while ion balance indicates the electrical balance of the generated ion output. Both are important parameters when evaluating an Ionizing Air Gun for ESD-sensitive work.
