Air Buffer for Finishing Work
The Dynabrade 51470 is an air-powered buffer built for automotive and machine-shop finishing. It accepts pads from 6 to 8 inches and runs at a free speed of 2000 rpm. The tool suits technicians who need consistent surface preparation without electric motors.
Integration with Compressed-Air Systems
Operation requires a 90 psi supply and a minimum 3/8 inch hose connected to the 1/4 inch NPT inlet. At full load the tool draws 41.0 CFM, while a 15-second test averages 10.25 CFM. The rear exhaust directs airflow away from the work surface and the composite handle reduces vibration transfer.
Capacity Limits and Practical Headroom
The 5/8-11 spindle secures standard buffing pads within the stated size range. The 13 inch overall length fits most bench and portable setups. An adjustable regulator lets the operator match speed to the task, though the 2000 rpm ceiling limits aggressive material removal.

Questions about this item
How long can the 51470 run continuously at 2000 RPM before the 10.25 CFM average over 15 seconds drops?
The tool is rated for 10.25 average CFM measured over a 15 second run time; sustained use beyond that interval will require the compressor to maintain 41.0 CFM at full load.
What sound and heat level should I expect when the buffer runs all day at 90 PSI?
Rear exhaust directs airflow away from the operator and the composite handle insulates against heat buildup during extended operation at 90 PSI.
Which compressor fitting and hose do I need to supply 90 PSI to the 1/4 NPT inlet?
Connect a 3/8 inch minimum hose to the 1/4 NPT air inlet; the compressor must deliver 90 PSI at up to 41.0 CFM for full-load performance.
