Frequently Asked Questions
What is a pneumatic needle scaler used for?
A pneumatic needle scaler is used to remove rust, paint, weld slag, and other surface contaminants from metal surfaces. It is ideal for ship hulls, steel structures, and casting surfaces.
What air compressor size do I need?
We recommend a compressor with at least 2 HP to ensure adequate air supply. The tool consumes 5 CFM at 90 PSI, so ensure your compressor can deliver that continuously.
Can the needles be replaced?
Yes, the 19 needles are replaceable. They are standard 3mm needles, and you can easily replace them when worn to extend the tool's life.
Is this tool suitable for irregular surfaces?
Yes, the needle design allows the tool to conform to irregular and contoured surfaces, making it effective on uneven metal, corners, and edges.
