Laser cleaning is a reliable, safe, fast and environment friendly technology intended for surface cleaning. This technology enables easy removal of rust, paint, oxidation, dust deposits and effectively degreases surfaces. Laser cleaning is an eco-friendly technology eliminating use of additional abrasives as in alternative technologies. Equipment durability, reliability, and low energy consumption led to widespread application of this technology in the industry. Femta offers laser cleaning systems that, depending on the model, cost between 20,000 and 49,000 euros.
High energy laser pulses are directed and focused on the layer to be cleaned. The pulses are absorbed by contaminants on cleaning surface causing them to instantly decompose by evaporating or turning to dust. For every cleaning process optimal pulse power is selected to ensure removal of contaminated layer, but not sufficient energy to cause any damage to base material. Any residue from decomposed materials can be removed with the help of fume extraction unit or can simply be wiped off. Cleaning process is repeated until all the dirt is removed from the cleaning surface. In case of transparent surfaces, such as varnish-coated surfaces, laser radiation can be absorbed by materials under the varnish. Due to local expansion of the base material under the varnish layer, transparent layer may lose its bond with base material and can be successfully lifted up without causing any damage to the base material.
The infrared wavelength of Femta offered laser cleaning systems is efficiently absorbed by oxides and organic substances such as rubber, paint, insulation, varnish, soot, etc.
Transportable laser cleaning systems consist of a laser light source, an optical cable of the desired length (up to 20 meters), and a laser gun. We offer 20-200 watt portable laser cleaning systems. Depending on the model, portable laser cleaning systems are capable of applications starting with precise preparation of a small surface areas to the removal of dirt from thick and large surface area materials. Femta also offers lightweight (<18 kg) backpack-type laser cleaning systems. Due to its portability and easy operation, this system is ideal for hard-to-reach places.
