Use of the latest technologies has allowed us to create a very powerful and energy-saving extraction and filter system series. In addition to special low-noise blowers, the systems are equipped with integrated acoustic insulation measures that achieve values of 51-53 db(A), which allows for use even in noise-sensitive environments. The energy savings as compared to traditional systems are another big PLUS for this system series. For example, the LN 265-GL 265 allows for energy savings of 85%. In contrast to the LN series, with the GL series you always have to make sure that the intake area is large enough.
