The Mirka® PROS 550NV (Non-Vacuum) Pneumatic Random Orbital Sander was developed in-house by Mirka’s industry-leading design team. Clever features and attention to detail make it an efficient and effective sanding tool that perfectly suits professional operators. Mirka® PROS 550NV has a 5 mm orbit and is especially designed for maximum dust extraction even at low suction power, due to a wider, more efficient dust suction outlet in the machine housing.
