3/16” vs. 3/32” Orbit - Choosing the Right Cut 

SurfPrep air orbital sanders and air sanding tools are offered in two orbit sizes:  

  • 3/16" orbit: more aggressive cutting action and quicker material removal. Perfect for early-stage stock removal, sealer sanding, and surface preparation  
  • 3/32" orbit: less swirl marks and a smoother scratch pattern. Best for finish sanding and ultimate surface preparation where quality is the emphasis  

Most professional shops operating an air orbital sander employ both orbit sizes - the 3/16” for cutting stages and the 3/32” for finishing stages.

Frequently Asked Questions 

Common questions about SurfPrep air tool sander and air sanding tools models: 

What is an air sander used for? 

An air sander is a pneumatic random orbital sander used for marine finishing, automotive paint preparation, furniture restoration, cabinet making, and woodworking. It works well in high-production settings when tool weight is important over a whole shift because it is lighter than electric models. 

What compressor do I need for a SurfPrep air sander? 

For continuous operation, SurfPrep air powered sanders need a high-capacity air compressor. The 3”×4” Storm demands 16 SCFM / 3.1 CFM at 90 PSI. Verify your compressor’s output against each model’s criteria before purchase. 

What is the difference between the Storm and Trident air sanders? 

The Storm is a small air orbital sander that works well for detail work, profiles, and narrow panels. It comes in 3", 3"×4", and 3"×7" sizes. The Trident is offered in 5” and 6” for general woodworking and big panel production sanding. 

Are SurfPrep air sanders dust extractor-compatible?
