LE-AN104 Industrial 19-Needle Air Scaler

4,000 BPM Impact | 19 Hardened Needles | Taiwan Precision

A Strategic High-Frequency Solution for Aggressive Rust Removal, Slag Cleaning, and Heavy Surface Preparation

19 Steel NeedlesHigh-Density Surface Coverage
2.16 KGOptimized Power-to-Weight
90 PSIIndustrial Operating Standard
In heavy industrial maintenance and shipbuilding, manual scraping is an inefficient bottleneck. The LEMATEC LE-AN104 utilizes a high-frequency pneumatic piston to drive 19 independent needles, creating a "hammering" effect that chips away stubborn rust, weld slag, and scale 10x faster than traditional methods. For B2B procurement, this ensures significant labor cost reduction and consistent metal prep quality for long-lasting coatings.

Precision Needle Dynamics

Equipped with 19 hardened 7-inch needles that rapidly oscillate to penetrate uneven surfaces. This design allows technicians to clean deep pits and irregular welds where standard grinding disks cannot reach, ensuring 100% surface integrity before recoating.

Ergonomic handle detail

Industrial Duty Mechanics

Constructed for high-vibration environments with a robust internal piston system. The LE-AN104 is balanced to minimize operator hand-arm vibration (14.5 m/s²), allowing for extended duty cycles in shipyards and heavy automotive repair bays.
