For sound dampening of low-frequency sounds in ventilation and air-conditioning installations with high hygienic requirements.

Membrane absorber in baffle design with completely smooth surface for use in installations with extremely high hygienic requirements or in ventilation ducts with large amounts of dust or dirt or subject to chemical stress. The membrane absorber shows a good resistance to chemical and mechanical stresses (i.e. in flow ducts subject to abrasive stress). Using the membrane absorber in RLT systems for kitchens, as requested in the VDI 2052, is possible without any problems.
