"In the new hall, the system works even better because the pipelines now run on straight and short routes. If we switch off the filter systems for half an hour during production, we can already see how necessary the system is for a better indoor air climate. - AXA plant manager, Georg Hullmann

AXA Entwicklungs- und Maschinenbau GmbH manufactures machine tools for metal cutting for an international clientele. The new hall, in which machine beds for machining centers are manufactured, houses the cutting, welding and sheet metal construction departments in addition to the cutting department. Employees work there in two shifts processing general structural steels. Smoke and dust are released in the process.

Due to the positive experience that the machine and plant manufacturer from the western Münsterland region had made with TEKA's push-pull system in recent years, it has adopted the extraction concept used up to now in its new building. It works as follows: Pipes are installed on both long sides of the hall at a height of about 4 meters. The pollutant-laden air produced during welding is drawn in on the side of the hall where most of the welding work is carried out and where most of the pollutants are generated. They are collected through openings in the piping and led to the three filter systems of type ZPF.

For space reasons they are installed outside the hall. This has the decisive advantage that noise pollution is also reduced to a minimum. The cleaned air is then returned to the working area via ventilation grilles on the other side of the hall. In this way, a continuous air flow is created which ensures that pollutants are continuously collected. Further energy savings are achieved by the summer/winter operation of the system, in which the cleaned warm air is fed back into the hall during the cold winter months. Employees in all areas of the hall are protected from harmful dust and smoking.

The advantages at a glance: ZPF

• IFA-certified extraction system for welding smoke class "W3
• Separation efficiency of filter cartridges of dust class M ≥ 99.9 percent
• self-cleaning cartridge filter system
