The sander is built on wheels so it can be moved around the shop and it has a built in air pump that will blow air up through the small balls counter sunk in the table. This creates an easy movement of parts on the table similar to an air-hockey table.
The sander has a built in inverter to control speed and it gives you a read out of your spindle speed on a digital read out.
