Burner-integrated extraction system for industrial use

The VacuFil series is compatible with all common extraction torches and is suitable for long-term industrial applications with large quantities of welding fumes. Because international standards will stipulate higher extraction capacities in the future, Kemper has already categorized the new family of mobile high-vacuum extraction units into different line classes.

Three basic analog versions and three digital solutions, each with extraction capacities of 125, 140 and 200 m³/h, will be available at the end of 2019. While welders can manually regulate the extraction capacity of the basic versions, the digital versions adjust the required air volume flow fully automatically.

Automatic power regulation like cruise control

"Like cruise control in a car, our digital VacuFil solutions regulate the required power based on the individual welding conditions," explains Kemper. "We have thus developed a unique system that takes into account different parameters, such as the torch power."

Welders intuitively select the respective welding torch via touch display and the device automatically adjusts the air volume flow based on the parameters stored in the device. During product development, Kemper created a database with the individual performance characteristics of different welding torches. A volumetric flow measurement constantly adjusts the required output. The Kemper cloud delivers updates for the various performance parameters directly to the device.

All variants are mobile and can be used for individual welding applications. The basic version with an air flow rate of 200 m³/h also has two connection nozzles and can therefore be used by two welders at the same time.

Modular filter system for easy retrofitting

In addition to the new burner-integrated extraction system, Kemper is also presenting a cost-effective filter solution for extraction installations that have so far managed without an effective filter for separating hazardous substances. The filter medium integrated in a compact housing can be easily retrofitted behind the relevant capture elements. The solution also enables contamination-free replacement of the disposable filter, which has the largest filter surface in this device class on the market with its 42^m2.

"This allows companies to feed the purified air back into the hall and not have to discharge it outside. This simple option not only ensures clean indoor air, but also saves energy costs, especially in winter," says Kemper.
