Different bore sizes allow you to match the blasting gun with different abrasive media, air compressor capacities, and surface treatment requirements.

4. Compatible with Various Abrasive Media

The sandblasting gun can be used with a variety of non-metallic blasting media, including:

• Glass beads

• Aluminum oxide

• Garnet

• Walnut shell

• Sodium bicarbonate

• Silica

• Ceramic media

• Other suitable abrasive materials

Always select blasting media appropriate for your equipment and application.

5. 1/2" Quick Connector

The gun is designed with a standard 1/2" quick-release coupling, making it compatible with many commonly used sandblasting hoses and air connections.

6. Versatile Blasting Applications

Ideal for:

• Rust removal

• Paint stripping

• Scale removal

• Glass blasting

• Polishing

• Metal surface treatment

• Automotive surface cleaning

• General abrasive blasting

Product Specifications

Recommended Air Compressor

For optimal performance, the product information recommends using an air compressor rated at approximately:

7.5 kW / 10 HP or above

Actual compressor requirements may vary depending on the nozzle bore size, operating pressure, blasting media, and desired blasting performance.

Abrasive Media Recommendation

The gun supports suitable non-metallic abrasive media in approximately 46–240 grit, depending on the specific application and nozzle configuration.

Suitable options may include:

• Glass beads

• Baking soda / sodium bicarbonate

• Aluminum oxide

• Walnut shell

• Garnet

• Silica-based media where permitted

• Other compatible non-metallic abrasives

Important: Abrasive size and moisture can significantly affect blasting performance. Use clean, dry abrasive media and avoid oversized particles that may clog the nozzle, sand valve, or blasting hose.

Troubleshooting

If the sandblasting gun does not blast properly, check the following:

1. Air Compressor

Make sure the compressor provides sufficient airflow and pressure for the selected nozzle.

2. Abrasive Media

Check whether the abrasive is suitable for the nozzle and gun. Oversized media can cause blockages.

3. Air Pressure

Check the operating pressure and adjust the regulator if necessary.

4. Sand Valve

Inspect the abrasive valve for blockage or improper adjustment.

5. Moist Abrasive

Moist abrasive can clump together and cause poor material flow or blockage. Always use dry abrasive media.

6. Sandblasting Hose

Check whether the blasting hose is blocked by foreign objects or accumulated abrasive.
