The Mirka PROS 550NV (MRP-550NV-G) is a 5 in. pneumatic non-vacuum random orbital sander engineered for efficient surface preparation and general-purpose sanding across woodworking, metalworking, composite, and automotive finishing applications. Powered by compressed air, this lightweight sander features a 5 mm orbit that delivers an ideal balance of fast material removal and smooth finish quality on flat and contoured surfaces.

Designed for continuous shop operation, the PROS 550NV features a low-profile, symmetrical body that provides easy handling with either hand. An integrated wrist support cover channels muffler exhaust air away from the user during operation, provides comfortable control, and functions as an access flap for the air supply line and safety lockout. A built-in pad brake system restricts free-spinning rotation when the sander is lifted off the workpiece, preventing surface gouging and swirling when re-engaging the material.

Features & Benefits

• 5 mm Orbit: Balances stock removal speed with smooth finish quality for general sanding and surface prep.
• Dual Backing Pad Inclusion: Comes supplied with both grip (hook-and-loop) and PSA (peel-and-stick) backing pads for complete abrasive attachment flexibility.
• Lightweight Composite Body: Weighs only 1.96 lbs. to minimize operator fatigue and arm strain during extended sanding operations.
• Symmetrical Ergonomic Design: Low-profile housing and balanced weight distribution allow comfortable control in either the right or left hand.
• Pad Brake System: Limits pad rotation during off-surface positioning to eliminate aggressive surface gouging upon restart.
• Integrated Exhaust Air Deflector: Directs exhaust air away from the operator's wrist while doubling as a safety lockout lever.
• Non-Vacuum Configuration: Ideal for open sanding environments where tethering to a vacuum extraction hose is not required.
