The METABO ASR35 ACP Vacuum meets or exceeds all regulatory standards concerning HEPA vacuums and provides the highest level of job-site dust containment. The ASR35 ACP is made in Germany. Use for extraction from the power tool in continuous mode, both on construction sites and in the workshop, this compact vacuum cleaner is great for removal of liquids and dry solids. Utilizes AutoCleanPlus to save costs and time thanks to automatic MPulse filter cleaning allowing for continuous use. If the vacuum senses a pressure difference from one side of the filters to the other, the filters are vibrated immediately, clearing the filters without interrupting suction.
