Technical specifications

• Primary use: removal of rust, weld slag, paint and contamination; effective on uneven or profiled surfaces with flexible needle arrays.
• Needle diameters available: 2 mm, 3 mm or 4 mm depending on model.
• Air supply: typical working pressure up to 6–7 bar; air consumption varies by model (96–158 L/Min ≈ 3.4–5.6 cfm).
• Connection threads: G 3/8", R 3/8" or G 1/4" depending on model.
• Acoustic power: commonly 101 dB(A); selected NP models rated at 109 dB(A).
• Weight range: approximately 1.3 kg to 5.7 kg depending on model and configuration.
• Typical needle counts (ø 3 mm): 12 to 49 needles depending on model (e.g., 12 B = 12, 23/NP 23/23 B ≈ 19, 34 variants ≈ 28, 45 variants ≈ 49).
