This high-efficiency vacuum optimizes the built-in dust-collection capability of Mirka tools to make sanding a practically dust-free experience. It delivers strong, consistent suction with a powerful turbine that creates a 250 mbar vacuum and 159 cfm of airflow, greatly reducing clean-up time while eliminating stray abrasive particles to help ensure better surface finishes and longer abrasive life. It also helps avoid health risks associated with airborne dust, with HEPA-certified filtration that removes at least 99.97% of particles as small as 0.3 microns.
