The Metabo ASR 35 H ACP is a powerhouse with which you can safely clean up dangerous substances such as asbestos or fungi. No dust particle gets the chance to damage the airways, due to the 2 built-in HEPA filter cassettes. The construction vacuum cleaner therefore has the highest Certification for dusts of substance class H. Since you can move forward with a 35-liter reservoir, it is no superfluous luxury that the ASR 35 H ACP is equipped with automatic filter cleaning. As a result, you are assured of optimal suction power, even if you are working for a long time. Afraid of annoying shocks you do not have to be: the antistatic hose prevents static charge when using power tools.
