For us, sustainability is the focus of every product development. Particular attention is paid to constantly rising energy costs. Since 2012, all elstar and mestar air filters have been equipped with modern EC fans. This significantly reduces electricity costs. With central systems, the amount of air and thus the energy input can be regulated as needed. The programming tailored to the application allows situation-dependent control of the system; this helps to save more energy.

Our new location, like our filter systems, is designed for sustainability.

The lighting consists almost entirely of modern LED lights, which significantly reduce the power consumption.

Our building is heated by connection to the district heating supply of the city Neu-Anspach. The heat production with wood, grown in the city forest, is resource- and climate-friendly.

On the roof of our building there is a 155 kW photovoltaic system, which underlines the importance of sustainability for us.

Our suppliers and business partners come almost exclusively from the region which enables us to react quickly and competently, as well as to ensure constant further development and our high standards of quality.

All of our products are "Made in Germany".

In addition, we are a partner of the Blue Competence sustainability initiative. Blue Competence ( is an initiative of the VDMA ( to promote sustainability in mechanical and plant engineering. With our partnership, we commit ourselves to compliance with the
12 sustainability principles of the mechanical and plant engineering industry.
