Pneumatic Air Needle Scaler Aerotec Pro 3000 min⁻¹, 19×3 mm needles, 24 mm piston

The Aerotec Air Needle Scaler Pro 3000 min⁻¹ is a pneumatic surface preparation tool designed for heavy-duty rust, scale and paint removal. The tool features multiple hardened steel needles with a 19×3 mm cross-section driven by a 24 mm piston delivering up to 3000 strokes per minute. Its construction and impact frequency make it suitable for weld cleaning, removing concrete spalls, chipping loose material and preparing metal surfaces prior to painting or coating.

Advantages

The needle scaler provides rapid material removal while allowing precise control over the work area. The 24 mm piston combined with the needle bundle produces consistent impact energy and an even working pattern. The tool’s pneumatic design ensures continuous operation under load without the thermal limitations of electric alternatives. Hardened needles are replaceable, enabling long-term use and straightforward maintenance.

Suitable for

• Weld seam cleaning and slag removal
• Removal of rust, scale and old paint from metal surfaces
• Chipping small areas of concrete or mortar
• Surface preparation before painting, galvanizing or coating
• Industrial maintenance and shipyard tasks

Key specifications

• Operating principle: pneumatic needle scaler
• Needle size: 19 × 3 mm (multiple needles)
• Piston diameter: 24 mm
• Maximum impact rate: up to 3000 strokes per minute
• Typical application area: metal, concrete, welds

How to use

Connect the needle scaler to a regulated compressed air supply that meets the tool’s recommended pressure and flow rates. Secure the workpiece or ensure the surface is stable before starting. Hold the tool with a firm two-handed grip and apply steady pressure while moving the needle bundle across the surface; avoid forcing the tool to prevent premature wear of needles. Periodically stop to inspect the surface and replace worn needles as needed. After use, disconnect the air supply, clean loose debris from the tool and lightly oil moving parts to prevent corrosion.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and gloves. Work in a ventilated area or use dust extraction when removing paint or rust. Match needle hardness and pattern to the task and replace needles in sets to maintain balance and consistent performance.
