The Mirka PROS 525NV (MRP-525NV-G) is a 5 in. pneumatic non-vacuum random orbital sander engineered for fine sanding and precision surface finishing applications. Powered by compressed air, this lightweight industrial sander features a 2.5 mm orbit designed to produce smooth, swirl-free surface finishes across woodworking, metalworking, composite, and automotive refinishing workpieces.

Designed for operator comfort during continuous operation, the PROS 525NV features a symmetrical, low-profile body that allows easy handling in either hand. An integrated wrist support cover shields the operator from the muffler exhaust air stream, provides two-handed stability, and can be lifted for quick air supply line access or used as a safety lockout lever. A built-in pad brake system limits free spin when lifted from the workpiece, helping prevent surface gouging upon re-engagement.

Features & Benefits

• 2.5 mm Fine Orbit: Delivers a tight, smooth sanding pattern optimized for ultra-fine surface prep and scratch-free finishing.
• Dual Backing Pad Inclusion: Comes equipped with both grip (hook-and-loop) and PSA (peel-and-stick) backing pads for complete abrasive versatility.
• Lightweight Composite Body: Durable composite housing reduces total tool weight to 2 lbs., minimizing operator fatigue during long sanding shifts.
• Symmetrical Ergonomic Profile: Low-profile design and balanced weight distribution allow easy, comfortable control with either hand.
• Pad Brake System: Restricts pad free-spin when lifted from the surface to reduce the risk of gouging or swirling upon restart.
• Integrated Air Deflector Cover: Channels exhaust air away from the user's wrist while functioning as an air connection access flap and safety lockout.
