Frequently Asked Questions
How does this compare to electric disc sanders?
Pneumatic disc sanders run cooler, maintain consistent speed under load, and never overheat like electric models. They're lighter weight, have fewer moving parts to fail, and provide better control for precision work. The main requirement is a compressed air source.
What air pressure and flow rate does this sander require?
This sander typically requires 90 PSI operating pressure and approximately 17 CFM airflow for optimal performance. Check your compressor specifications to ensure adequate air supply. Most shop compressors can easily handle this requirement.
Can I use standard sanding discs with this tool?
This sander is designed for 2"-3" discs and works best with 3M Roloc quick-change discs and backup pads. The dual mount system allows direct mounting of Roloc pads or use with standard 1/4" arbor accessories through the collet mount.
What makes the 97-degree head design better?
The 97-degree angle allows your wrist to stay in a natural position during operation, reducing fatigue and improving control. This is especially important for extended use sessions and when working on vertical or overhead surfaces.
