The AIR LOCKER AT100S is a straight-line air sander built for serious sanding work. Its dual piston design pushes out up to 2,500 strokes per minute, giving you fast, consistent material removal without wearing yourself out. The tensioned spring clamps let you swap sandpaper quickly, and the 2-3/4 inch x 15-3/4 inch pad covers a solid amount of surface in each pass. The two-handle design keeps vibration in check so you stay comfortable through long sanding sessions.
Why Consider This Product?
If you need to sand large areas quickly and get a consistent finish, the AIR LOCKER AT100S is worth a close look. It combines a high stroke rate with a wide pad and practical design features that hold up through real, regular use.
Users who have put the AT100S to work on wood, metal, and automotive bodywork report strong, repeatable results. The build quality reflects a tool designed for the shop floor, not just occasional weekend projects.
Features and Benefits
Maximum Efficiency with Dual Piston Design
The dual piston design drives the pad at up to 2,500 strokes per minute. That speed translates directly into faster material removal and a smoother finish without extra effort on your part. A job that would take hours by hand gets done in a fraction of the time.
Easy Sand Paper Changes with Tensioned Spring Clamps
The tensioned spring clamps let you change sandpaper without tools and without fumbling. Release, swap, clamp down and you are back to work in seconds. When you are moving through multiple grits on a single project, that speed adds up.
Comfortable and Vibration-Free Operation
The two-handle layout spreads the load across both hands and cuts down the vibration you feel during operation. Less vibration means less hand fatigue over a long session and better control over where the pad is cutting.
Smooth and Reliable Power with Quick Action Paper Clamps
The quick-action paper clamps grip the sandpaper firmly so it does not shift mid-stroke. A sheet that moves around leaves uneven marks and wastes your time. With the paper locked in place, you get a consistent cut from start to finish.
Product Quality
The AT100S is built for regular, heavy use. The construction feels solid, and the internal components hold up well under sustained air pressure and high stroke rates. This is not a tool that will wear out after a few weekends on the job.
What It’s Used For
Removing Imperfections
The AT100S works on wood, metal, and plastic where you need to level rough spots, raised grain, or surface defects. The wide pad covers ground quickly, and the high stroke rate cuts evenly without leaving deep scratches behind.
Preparing Surfaces for Finishing
Paint and varnish need a flat, smooth base to adhere properly and look clean. The AT100S knocks down high spots and scuffs the surface evenly so your finish coats go on right. The quick-change clamps make running through progressively finer grits a fast process.
Restoring Old Furniture
Stripping old paint, varnish, or stain from furniture is exactly where this sander earns its keep. The straight-line action follows wood grain cleanly, which reduces cross-grain scratching and leaves the surface in good shape for refinishing.
Automotive Repairs and Restoration
Body shops and home garage mechanics use straight-line sanders to level body filler and feather paint edges before priming. The AT100S handles both tasks well, producing a flat, consistent surface that is ready for primer without a lot of extra hand work.

Tips and Tricks For Best Results
- Check that your air compressor can maintain the required operating pressure throughout the job. A compressor that drops pressure mid-task will hurt your results.
- Match your sandpaper grit to the job. Start coarse to remove material quickly, then work up to finer grits to get a smooth, ready-to-finish surface.
- Clear debris off the sanding pad regularly. A clogged pad loses cutting ability fast and can leave scratches.
- Let the sander do the work. Light, consistent pressure gives you better results than pushing hard into the surface.
- Wear safety glasses and a dust mask every time you sand. Fine dust builds up quickly and is hard on your lungs and eyes.
