5 in Air Random Orbital Sander

The Dynabrade 56819 is a palm-style air sander built for industrial finishing work. Its 5 in PSA pad and 3/16 in orbit diameter suit surface preparation on metal, composite or wood. The tool runs at 12 000 RPM free speed with a 0.28 hp motor and lever throttle control. Rear exhaust directs airflow away from the workpiece.

Upgrade from non-vacuum palm sanders

This model adds integrated vacuum capability to capture dust at the source, reducing cleanup and airborne particles. The jump is worth it when a shop needs consistent finish quality and healthier air without adding a separate extraction arm. It requires 90 psi supply pressure and delivers 4.5 average CFM at a 15 second run time.

18.0 CFM full-load demand sets compressor sizing

At full load the sander draws 18.0 CFM, so the compressor and 1/4 in minimum hose must sustain that flow without pressure drop. The 1/4 in NPT inlet and 5/16 in-24 spindle accept standard industrial fittings. Shops with undersized air systems will see speed loss and orbit inconsistency under continuous use.
