Frequently Asked Questions

Q: What air compressor pressure is recommended for this pneumatic orbital sander?

A: Most pneumatic orbital sanders of this type operate best at 90 PSI (6.2 bar) with an air flow of approximately 4–6 CFM. We recommend checking the product model's included specification sheet and ensuring your air compressor can sustain the required CFM for continuous operation.

Q: What is the difference between the four available models (A, B, C, D)?

A: All four models — B9201A, B9204A, B9202A, and B9203A — share the same 5-inch pad size and 5.0mm orbital throw. The models may differ in internal valve configuration, body design, or air inlet placement. Please refer to the model images or contact us for specific model comparison details before purchasing.

Q: What sanding discs are compatible with this sander?

A: This sander is compatible with standard 5-inch (125mm) hook-and-loop (Velcro-style) sanding discs, which are widely available in a full range of grits from coarse (40–80 grit) for heavy material removal to fine (220–400 grit) for smooth finishing and polishing passes.

Q: Is this sander suitable for automotive polishing applications?

A: Yes. The 5.0mm random orbital throw and high-speed air-powered action make this sander an excellent choice for automotive bodywork, including paint prep, primer sanding, and surface finishing on panels. Pair with appropriate polishing pads and compounds for best results.

Q: Does this sander come with sanding discs included?

A: The sander unit does not typically include sanding discs. Discs are available separately. We recommend purchasing a multi-grit variety pack to cover all stages of your sanding and finishing workflow.
