Vreden – Thanks to innovative filter technology with increased efficiency in air pollution control: With PlasmaFIL, KEMPER GmbH presents a solution with an extremely long useful life and filter service life. The system is particularly suitable for the elimination of large quantities of dust specifically in plasma cutting. Thanks to its special design, regular overhauls of the filter are not necessary. From the moment it came on the market, the manufacturer already recorded its first sales success.

“With our new product, PlasmaFIL, we are closing a very important gap in the market”, says Managing Director, Bjorn Kemper. “Thanks to its special way of functioning, the useful life of the filter cartridge is extended significantly.” Regular filter changes are no longer required. Service lifetimes are nearly unlimited.

Newly developed plate filter, a central element
The core of the new system is an innovative plate filter with a special coating, which also cleanses the air of ultra-fine dust particles. Due to the flow of untreated air in the top of the filter system with the down-flow principle, the filter was designed like a plate and not like a cylinder, as was previously the case. This has the following advantage: Contrary to the round filter cartridge design, the individual pleats in the filter do not move on top of each other, which prevents them from sticking together. In this way, the entire surface of the filter is used in the filtering process.

“Due to the possibility of filtering large amounts of dust with PlasmaFIL, the new filter system was developed specifically for use in plasma cutting machines”, emphasizes Kemper. The integrated spark pre-separator, SparkTRAP, also contributes here. Through the pre-separation of coarse dust particles and sparks, it prevents filter fires and reduces the level of strain on the filter. Positive side effect: Energy consumption of the filter system is considerably reduced and the service life of the filter is extended.

Contamination-free dust removal
Compared with conventional filter systems, PlasmaFIL does not even use a dust container. With DustEVAC, KEMPER relies on a vacuum-based disposal for the PlasmaFIL. The dust is collected in a high capacity BigBag. This enables contamination-free disposal and can, contrary to conventional containers, be changed during the cutting process without having to interrupt the work.

With the installation of a separate, silenced ventilator, the noise pollution can also be kept at a low level. Users operate and monitor the system via a central touch screen. It is even possible to communicate with the plant engineering department or to integrate it into the software of connected equipment. A start-stop function is integrated as a standard feature.

voestalpine subsidiary relies on filter design
The feedback on the new KEMPER product could not be any better: From the moment it came on the market, the equipment manufacturer already recorded its first sales success of the high-end extraction solution. “This innovative filter concept has convinced us with its very high service lifetimes”, says Walter Radinger, Process Manager of Cut Shapes at the Austrian company voestalpine Anarbeitung GmbH, a full subsidiary of the publicly-listed company, voestalpine AG. At the moment, there is no other comparable plate filter solution on the market. “We anticipate that with the help of this new system, we can considerably reduce the otherwise usual operating costs of our filter systems.”

The metal-processing company can even use the new filter system completely without having to purchase it, thanks to the new sales concept at KEMPER. Instead of purchasing the systems, interested parties may also rent them from the manufacturer. In conjunction with the filter’s service life guarantee and full service contracts, consequential costs remain low and can be accurately calculated.
