The unit has an extra large HEPA H13 filter surface to ensure low-noise gas and particle extraction. It has a maintenance-free and brushless EC blower which guarantees an extraction volume of 190 m3/h and a strong vacuum of 3000 Pa. The unit runs quietly and the automatic filter monitoring system and the audiovisual filter alarm alert the user in plenty of time when a filter change is due. The filter can be changed quickly and easily.
 
The extra large filter surface gives the HEPA H13 filter a long service life, guaranteeing a high level of particle filtering. The F7 pre-filter also increases the service life for applications with a high flux content or volumes of fine dust. In addition, the extraction power and/or the volume flow of the Zero Smog TL can be variably adjusted depending on the application requirements and the number of workplaces. The activated carbon filter provides effective gas cleaning.
