The Mirka PROS Pneumatic Non-Vacuum 6 Inch 8mm Orbital Sander, model MRP-680NV, is a pneumatic random orbital sander built for professional sanding and surface preparation. This is a random orbital sander designed for rapid material removal and heavy-duty finishing applications. If you need a 6 inch air sander that stays light in the hand and is aimed at production work, this one is set up for exactly that kind of use.

The big story here is the 8 mm orbit. That wider orbit is a practical choice for faster sanding, especially when you are leveling filler, working through prep stages, or covering larger areas where speed matters. It is not trying to be an ultra-fine specialty finish sander first. It is built to remove material efficiently while still giving you the control and surface consistency you expect from a random orbital design.

Mirka also put real attention into how the tool feels during long runs. The published weight is 2.98 lbs, which helps when you are sanding doors, body panels, tabletops, or other broad surfaces for extended periods. A lighter air tool is easier to guide, easier to hold flat, and less tiring at the end of the day. The product information also calls out a comfortable grip and easy handling, which matters on a tool that may stay in your hand for hours instead of minutes.

This is the non-vacuum version, so it is the right pick for users who do not need an onboard vacuum connection on the tool itself. That makes the Mirka PROS Pneumatic Non-Vacuum 6 Inch 8mm Orbital Sander a straightforward option for sanding setups where air power and pad performance matter more than an integrated dust-extraction configuration. It ships with the sander and pad, so you have the core pieces needed to get the tool into rotation.

In real shop use, this kind of 6 inch orbital sander makes the most sense for automotive refinishing, composites work, furniture production, and marine refinishing where broad-panel sanding is common. The 6 inch pad size covers ground efficiently, and the pneumatic drive keeps the tool ready for repeated daily use in a professional environment. If your workflow already revolves around compressed air tools, this fits in without adding another battery platform or corded setup to manage.

Who should buy it? Pros and serious users who want a light, air-powered finishing and prep sander with a more aggressive orbit than a fine-detail model. If your work leans toward fast sanding, surface prep, and production-minded efficiency, the MRP-680NV is a smart fit. If you specifically need a vacuum-ready sander, you will want to look at a different version instead of forcing this one into the wrong setup.
