Air sanders are among the most useful tools in woodworking, metal fabrication, and auto body repair. But here’s the catch: not every compressor can power every type of sander. If you’ve ever wondered, “What air sanders can I use with my compressor?” the answer depends on two things—your compressor’s CFM (airflow) and PSI (pressure). This guide explains the different types of sanders, the air requirements they demand, and which compressors are best suited for running them without interruptions.
Quick Picks: Best Compressors for Air Sanders
- Best Overall: Ingersoll Rand 2475N7.5-P — Reliable two-stage compressor for running DA and belt sanders.
- Best Budget: California Air Tools 10020C — Quiet, affordable for light orbital sanding.
- Best Premium: Quincy QT-7.5 — Heavy-duty compressor for continuous sanding operations.
Buyer’s Guide: Matching Sanders to Compressors
1) Orbital Palm Sanders
These compact sanders typically use 4–6 CFM at 90 PSI. They can run on small shop compressors (20–30 gallons), but for long sessions, a 60-gallon two-stage is ideal.
2) Dual-Action (DA) Sanders
Common in auto body work, DA sanders require 8–12 CFM at 90 PSI. You’ll need a larger 60–80 gallon compressor for continuous use.
3) Belt Sanders
Air belt sanders use 10–15 CFM. These demand a shop-grade compressor to avoid frequent cycling.
4) Straight-Line Sanders
For auto refinishing, straight-line sanders can draw 12–15+ CFM. These are strictly for large compressors with continuous-duty ratings.
5) Die Grinder Style Sanders
Mini sanders and grinders often require 4–8 CFM, making them usable on smaller compressors for short bursts.
Rule of Thumb
Your compressor’s CFM rating should be 25–30% higher than your sander’s requirement for reliable, uninterrupted use.

FAQ
Can I run a DA sander on a small pancake compressor?
No. DA sanders require 8–12 CFM, far more than pancake units can deliver.
What compressor size is best for woodworking sanders?
A 60–80 gallon, 5–7.5 HP two-stage compressor ensures steady sanding without pressure drops.
How many sanders can I run at once?
That depends on CFM. For example, a 24 CFM compressor can usually run two DA sanders simultaneously.
Do rotary screw compressors work better for sanding?
Yes. Rotary screws deliver continuous airflow, making them perfect for body shops and furniture plants.
What PSI should I set for sanding?
Most air sanders run best at 90 PSI. Always check your tool’s rating.
Conclusion & Call-to-Action
So, what air sanders can I use with my compressor? The answer depends on CFM. Orbital sanders work on smaller compressors, but DA, belt, and straight-line sanders require large two-stage or rotary screw units. For most shops, the Ingersoll Rand 2475N7.5-P is a perfect match. Heavy-duty users should look at the Quincy QT-7.5 or EMAX 7.5 HP for nonstop sanding performance.
