ST / ST1 / ST1S BLASTING GUN

What is the Iwata ST / ST1 / ST1S Blasting Gun and why choose it?

The Iwata ST, ST1 and ST1S blasting guns are professional sandblasting guns designed for surface preparation on small, medium and large areas. Belonging to the Anest Iwata sandblasting series, they are engineered for reliable performance in workshops and body shops that need efficient removal of rust, old coatings and surface contamination before painting or coating. The range combines robust construction with treated steel nozzles for improved wear resistance when working with abrasive media. Some details may vary depending on region and production year and are not fully verified; always check the official technical datasheet for confirmation.

Main features

• Complete sandblasting range: Three models (ST, ST1, ST1S) to cover large, small and medium-small blasting areas.
• Self-priming options (ST and ST1S): Use a suction hose to draw abrasive media directly from a container, ideal for continuous work on larger surfaces.
• ST1 with integrated container: Supplied with approximately 1 litre pot, suitable for small, localized blasting jobs (capacity value based on typical published data, to be confirmed in the official datasheet).
• Treated steel fluid nozzles: Inner and outer fluid nozzles in treated steel to resist wear from abrasive media and help extend service life.
• Adjustable outer nozzle (ST1S): Extension-type adjustable outer nozzle on certain models for better control over the blasting pattern (information based on manufacturer literature, not independently verified).
• Sand suction hose (ST and ST1S): Hose supplied on self-priming models to pick up abrasive from an external container, enabling flexible positioning of the blast media.
• Optimised for compressed air systems: Designed to work with workshop compressors providing adequate airflow and pressure for sandblasting (exact required values depend on the model; consult the official datasheet).
• Professional build quality: Part of the Anest Iwata professional coating and surface preparation range, suitable for demanding workshop use.

Applications and use cases

• Automotive body repair: Removal of rust, paint and coatings from panels, chassis components and small parts before refinishing.
• Industrial maintenance: Cleaning and preparing metallic structures, machinery components and tools for repainting or coating.
• Surface preparation for coating: Creating an even, roughened profile on metal surfaces to improve adhesion of primers, paints and protective coatings.
• Localized repair work: ST1 with container is especially suitable for small zones or spot repairs where a cabinet blaster is not available.
• Workshop and garage use: General cleaning of heavily soiled or corroded parts where mechanical or chemical cleaning would be less effective.

Always select the grit type and size of the abrasive media according to the substrate and the coating system requirements, and follow the recommendations in the official technical and safety documentation.

FAQ

1. What is the difference between the ST, ST1 and ST1S blasting guns?

The ST is a self-priming gun intended for large areas using an external abrasive container. The ST1 includes an integrated container (around 1 litre) for small jobs. The ST1S is also self-priming with a longer suction hose, designed for medium-small areas. Some details may vary by version, so consult the official datasheet to confirm.

2. What kind of compressor do I need?

The guns require a compressor capable of providing a relatively high airflow at approximately 6 bar of working pressure. Exact consumption depends on the specific model and nozzle size and is not fully verified here; you should check the official Anest Iwata technical datasheet to dimension the compressor correctly.

3. Which abrasive media can I use?

These guns are generally designed for common sandblasting abrasives such as mineral grit or similar media suitable for dry blasting. The exact compatible media types and grain sizes depend on the manufacturer recommendations and are not fully detailed here, so you should refer to the official documentation and local safety regulations.

4. Can I adjust the blasting pattern?

On typical ST1S and some ST configurations, the outer nozzle is described as extension-type and adjustable, allowing you to modify the blasting pattern to suit the workpiece. The exact adjustment range and method should be confirmed in the user manual.

5. Are spare parts available?

Yes, Anest Iwata normally offers spare nozzles, air caps and seals for the ST, ST1 and ST1S series. The specific spare part references depend on the model version; check the official parts list or contact an authorized distributor.

6. Can I use the ST1 in confined spaces?

The ST1 with integrated container offers good manoeuvrability in tighter areas compared with a cabinet blaster, but sandblasting generates dust and rebound. Use it only in well-ventilated areas with appropriate containment, and always wear suitable personal protective equipment as indicated in the safety instructions.

7. Is this gun suitable for professional body shops?

Yes, the ST / ST1 / ST1S blasting guns are part of the professional Anest Iwata range and are widely used in workshops and body shops for surface preparation. Ensure that your compressed air system and safety measures meet the manufacturer’s requirements.

8. Can I use these guns with other fluids instead of abrasive?

They are specifically designed for sandblasting with abrasive media. Using them for other types of fluids or chemicals not recommended by the manufacturer can damage the equipment and may be unsafe. Always follow the official usage instructions.

9. How do I maintain the blasting gun?

After use, blow out remaining abrasive, check the condition of the treated steel nozzles and seals, and replace worn parts in line with the manufacturer’s guidelines. Detailed maintenance instructions are given in the official manual, which should be consulted for accurate procedures.

10. Where can I find exact technical data?

Exact figures for air consumption, maximum working pressure, weight and other parameters can change between versions and are not fully verified here. For precise, up-to-date information, always consult the official Anest Iwata technical datasheet and documentation for the ST / ST1 / ST1S blasting gun series.

Section 14: Transport information

The Iwata ST / ST1 / ST1S blasting gun is a piece of equipment, not a chemical, so it is generally not classified as a dangerous good for transport in the same way as compressed gas cylinders or chemical products. However, the following aspects should be considered:

• Transport conditions and legal requirements can vary by country and are not detailed in the available product information.
• Abrasive media and any associated chemicals (such as surface treatments or cleaning agents) may have their own transport classifications, which are not covered here.

Because specific transport classifications (for example ADR, IMDG or IATA codes) are not provided in the consulted product information and are therefore not verified, always refer to the official documentation from Anest Iwata and the safety data sheets of any associated materials before shipping or transporting the equipment and consumables.

Section 8: Individual protection measures

Sandblasting operations generate dust, rebound particles and high noise levels. The following individual protection measures are general, not specific to this model, and are provided as non-verified guidance. You must always follow the official safety instructions and applicable regulations:

• Eye and face protection: Use safety goggles or a full-face shield approved for impact from high-velocity particles.
• Respiratory protection: Wear an appropriate respirator or air-fed helmet suitable for dust, depending on the abrasive type and workplace limits.
• Hand protection: Use abrasion-resistant gloves suitable for handling abrasive media and blasted parts.
• Body protection: Wear protective clothing or a blasting suit to protect skin from rebound abrasive and dust.
• Hearing protection: Use ear defenders or earplugs rated for the noise levels produced by the compressor and blasting process.
• Foot protection: Safety footwear with closed toes and, where required, reinforced caps and slip-resistant soles.

These protective measures are based on common sandblasting practice and are not specific, verified data for this product. For exact requirements, always consult the official manual, the safety data sheets of the abrasives used, and local occupational safety regulations.
