The Mirka® PROS 550 SGV (self-generating vacuum) pneumatic random orbital sander was designed by our team of industrial design experts. Great attention to detail combined with ingenious features make it an efficient, high performance sanding tool that is perfectly suited to the needs of professionals. The MRP-550SGV has a 5” dia and 5 mm orbit. and is designed for maximum dust extraction, even with low suction power: its wider opening for dust suction considerably improves extraction. This sander is equipped with a new type of non-woven dust bag with a much larger capacity and an unequaled lifespan compared to similar products found on the market. Unlike paper dust bags of this kind, there is no need to protect this non-woven dust bag with a security nylon bag.
