Lasers are welding metal or plastic components, they are cutting sophisticated contours and they are marking and structuring surfaces. Also printing and medical technologies benefit from laser technologies. But all of them share one problem: laser fume. Laser fume No matter, whether processed materials are harmless — laser fume is not. The energy input during processing triggers pyrolytic and oxidation processes. They release a caustic, toxic mix of aerosols, gases and nano particles. The latter are extremely hazardous, as during inhalation they overcome the lung-blood barrier and enter the...

With operating processes, extraction precedes filtration. When selecting fume extraction technology, however, the reverse order applies. The first question calls for an adequate filtration system. LAS systems offer users the choice between two alternatives. Saturation filter units Saturation filter units are mainly used, where the amount of laser fume is comparably small, for removal of sticky laser fumes and for odorous emissions. Dusts and gaseous pollutants are retained by the filtration systems; the purified air is fed back into the work area. At the end of their service lives,...

Cartridge filter units Cartridge filter units are mainly used to re move dry, intensive laser fume in rather high volumes. They feature long service life and low operating costs. Pollutants are collected on the surface of the filter cartridge. The filter cartridge is de-dustible. At intervals, the cartridge gets cleaned with compressed air counter-flush and the dust is completely gathered in dust collectors. Purified air is fed back into the work area. Pollutant particle Filter cartridges Purified air Particles blown off Dedusting air blast Dust collector Cartridge filter units » For high...

Type and volume of the laser fume are not the sole criterion when selecting the adequate filter system. The required extraction capacity is also of key importance. Work place and suction environment are essential here. LAS saturation filter units are primarily designed for low to medium laser fume intensity. They are suitable for numerous single-user workstations in labs, manufacturing or industry. The normally small footprint of saturation filter units brings some advantages into play: compact and mobile solutions. LAS saturation filter units LAS Volume Vacuum Nominal Series flow max. max....

LAS cartridge filter units LAS Volume Vacuum Nominal Series flow max max. capacity For high laser fume intensity, LAS cartridge filter units are the devices of choice. Due to integrated dust collectors they require slightly more space than saturation filter units. The highest-performing units are stationary devices. They are perfectly suited for extraction at large or central systems. They effectively remove high volumes of laser fume. Example of cartridge filter units: LAS 300, LAS 500 and LAS 1500

An eye on the real laser process. Flexible performance Quite often, an individual work place is used to process different materials with changing laser tools, or occasionally it may be foresee able from the outset that the laser system will be expanded and the fume extraction technology must then grow accordingly. Simple module replacement helps to increase suction capacity within the range of a given filter system, or even change the filter system by substituting the main filter module. Special pre-filter and post-filter modules can be added as well as interchangeable capturing elements....

Individual capturing place. ULT selects it from the portfolios of leading suppliers of collection elements. Often, the design will be adapted, to come to grips with the discharge impulse of pollu tion particles created by the laser process or even benefit from it for energy savings. Quality of pollutant collection is the linchpin of fume extraction technology. In particular, closest proximity to the source of pollution is of critical importance: e.g. doubling the distance means a fourfold increase in re quired suction capacity and an exponential increase in energy consumption, to collect...
