This backpack-style pulsed laser cleaning machine features a lightweight, wearable design with an integrated air-cooling system, eliminating the need for an external chiller and allowing for single-person, mobile operation. Powered by pulsed "cold" laser technology, it removes rust, old paint, oxide layers, oil stains, and welding slag from metal surfaces without damaging the substrate. The process generates minimal heat, leaves no scratches, requires no chemical agents or consumables, and is environmentally friendly.
Suitable for diverse environments—including outdoor sites, high-altitude locations, pipelines, and construction zones—the lightweight, flexible handheld laser gun adapts easily to tasks such as rust removal and refurbishment in confined spaces or on large workpieces. Equipped with an intelligent control system, the unit allows for adjustable cleaning widths and pulse parameters, ensuring uniform, efficient cleaning and stable, continuous operation. This significantly reduces labor and post-processing grinding costs.
Available in various power specifications, the machine is widely used in industries such as mold maintenance, ship refurbishment, bridge and pipeline inspection, automotive chassis rust removal, cultural relic restoration, municipal adhesive and graffiti removal, and pre-weld treatment. Fully certified for safety and environmental compliance, and easy to transport, it is an ideal choice for mobile surface treatment at project sites.
