DFL Ventus Marker
Business Fibre
20–70 W

The DFL Ventus Marker from the Business Fibre product series is ideal for marking metals. This high-performance fibre laser offers variable pulse widths for challenging applications. Its exceptional beam quality obtains outstanding marking results. All its optical, electronic and mechanical components are integrated in a compact housing. The laser head can be detached as required. The Business Fibre series offers users a choice of power output levels between 20 and 70 W.


The fibre laser systems in the Business Fibre product series are suitable for use in time-critical manufacturing processes. They specialise in marking metals. Additionally, these systems can be used to mark plastics, ceramics and laser films. For maximum flexibility, systems in the Business Fibre series allow the user to adjust the pulse waveforms to their requirements. The result is superb, precision marking results that satisfy even the most stringent quality standards. All fibre lasers feature an air cooler. This enables the system to run for longer without the need for laborious maintenance work.

These systems are a laser safety class 4 solution. To upgrade them to laser safety class 1, ACI's laser systems can be purchased in conjunction with a laser station. Depending on the application, the lasers can either be used as an all-in-one solution in one of these manual workstations or they can be integrated into an automated production line.



The laser system is controlled using our proprietary Magic Mark marking software. This software enables workpieces to be marked with text, graphics, codes (data matrix codes, barcodes), serial numbers and logos. It can also be used to achieve uniform markings around the perimeter of workpieces with rotational symmetry. An intelligent user privilege management system facilitates the creation of different user groups. This way, the laser system can be adjusted to cater for the user's specific requirements. When using the laser system in automated production lines, fully automated operation – including data exchange with various data sources – can be achieved without any difficulties. Optionally, plugins such as the code or script module can be used to add extra functions to the Magic Mark software.
