Precision Drum
The precision machined drum insures sanding very flat, smooth surfaces without vibration.
The conveyor belt is driven by a 1/30 HP DC motor. Using this special variable speed motor also allowed the development of our patented SandSmart™ technology discussed in detail later in this article
Using these two high quality motors means you have plenty of power for even the toughest jobs. They also provide the flexibility and control you need for precision sanding.
The JET 22-44 Pro-3 Drum Sander is controlled with an industrial style magnetic switch that protects the motor from potentially harmful power fluctuations. This switch also has a safety function because it prevents the machine from restarting on its own should the power go out and then come back on unexpectedly. Once the power goes out, the operator must push the On button to restart the JET 22-44 Pro-3 Drum Sander.
Motors and Switching
The JET 22-44 Pro-3 Drum Sander uses two independent motors, one turning the sanding drum and the other the conveyor belt. The larger motor for the drum produces 3 HP on
The 3 HP primary motor that drives the drum (left) and the 1/30 HP motor that 1 phase, 230V (only) controls the conveyor (right) make the JET 22-44 Pro-3 more versatile. Using power. This TEFC (totally
