DYNABRADE

Q: What size air compressor do I need to run a DYNABRADE sander?

Pneumatic sanders are air hogs. Most DYNABRADE Random Orbital Sanders require at least 14 to 16 SCFM (Standard Cubic Feet per Minute) at 90 PSI to run continuously. You will typically need a 60-gallon, 5-HP or larger 2-stage air compressor for uninterrupted professional use.

Random Orbital Sanders (ROS)
The key to a flawless paint job is the orbit size of your sander. DYNABRADE color-codes their levers for easy identification. Use a 3/16-inch orbit (black lever) for aggressive material removal and body filler shaping. Switch to a tighter 3/32-inch orbit (silver lever) for ultra-fine clear coat finishing and polishing.

The Legendary Dynafile
For grinding welds, deburring metal, or finishing in impossibly tight spaces, the Dynafile abrasive belt tool is essential. Available in multiple belt sizes and with interchangeable contact arms, the Dynafile allows you to grind and polish inside channels and corners where standard angle grinders cannot reach.

What is the difference between non-vacuum, self-generated vacuum, and central vacuum sanders?
Non-vacuum models do not collect dust. Self-generated vacuum models use the tool's own exhaust air to pull dust into an attached filter bag. Central vacuum models feature a port designed to hook up directly to a heavy-duty shop dust extraction system for the cleanest possible work environment.
