Clean production air for all employees, even in small companies: KEMPER is expanding its CleanAirTower series especially for air pollution control for sporadic welding. With the two CleanAirTower SF 5000 and SF 9000 models, the manufacturer of extraction units and filter systems is launching two general ventilation systems with storage filters onto the market. Thanks to Cloud connectivity on the KEMPER Connect portal, all parameters can be monitored from anywhere at any time. KEMPER recommends the systems as a supplement to source extraction.

“Clean hall air for all staff in the entire production area is a real benefit for employers in the context of the shortage of skilled workers", says Björn Kemper, CEO of KEMPER GmbH. “General ventilation systems as a supplement to source extraction protect not just the welders themselves. They are therefore an important component for effective air pollution control". With the extension of the CleanAirTower series, KEMPER now also offers a room ventilation solution for low fine dust loads.

Extraction solution for sporadic welding
KEMPER is expanding its filter tower series with two variants. Both variants are particularly suitable for air pollution control in small welding companies with sporadic welding and low levels of welding fumes. Whereas the CleanAirTower SF 5000 has an extraction capacity of 5,000 m3/h, the CleanAirTower SF 9000 is capable of cleaning 9,000 m3 of air per hour. Thanks to their comparatively low height, they can also be installed in plants with low ceiling heights.

The use of replaceable storage filters results in lower investment costs for businesses than cleanable filters. Because different filter media can be integrated in the systems, the new CleanAirTowers from KEMPER are also suitable for production environments beyond metal processing, such as those in the logistics sector.

Greater extraction capacity for higher welding fume levels
Both room ventilation systems function according to the layer ventilation principle recommended by the trade association. They capture welding fumes in a 360-degree radius at a height of 2.70 or 3.40 metres respectively and separate even ultra-fine dust particles to more than 99.9 percent. 

Employees can switch on a new TurboBoost mode if the concentration of hazardous substances is extremely high at times. This temporarily increases the extraction capacity by around 30 percent, which allows the towers to capture more contaminated air for a limited period of time and reduce welding fume ceilings more quickly. Even at the highest power level, the noise level is only 76 dB(A).

IoT capability simplifies processes
Thanks to the simple connection to the KEMPER Connect portal, the manufacturer realises energy- and process-efficient operation. The general ventilation systems network with the Cloud in just a few moments via a mobile wireless-based connection. All relevant data flows into the Cloud in real time. Users can intuitively put together individual dashboards and user interfaces.

The portal is able to control the CleanAirTower automatically – for example, when the AirWatch air monitoring system from KEMPER measures high concentrations of hazardous substances that threaten to exceed legally prescribed limit values. The permanent recording and evaluation of relevant process parameters also enables predictive maintenance – and even paves the way for Smart Maintenance. In the web-based IoT solution, service employees have full control over their general ventilation systems anywhere and at any time.

The CleanAirTowers are suitable as a supplement to source extraction during welding. They protect welders and employees at nearby workplaces – especially in cases where welding fumes are not completely captured or source extraction is practically impossible. The general ventilation systems also help ensure that companies act in accordance with the law within the framework of increasingly stringent legal regulations.
