JET 22-44 Pro-3 Drum Sander

Our JET 22-44 Pro-3 Drum Sander quickly became a
favorite of wood workers because of its durability, huge
capacity, ease of use and exceptional surface smoothing
capabilities. In addition to the wide range of sanding grits,
our variable feed rate and exclusive SandSmart™
technology provide unrivaled control over the sanding
process.

The JET 22-44 Pro-3 Drum Sander has the capacity to
handle surprisingly large jobs despite its 52”-tall by 41”­long dimensions. The JET 22-44 Pro-3 Drum Sander can

sand material up to 4”-thick and 44”-wide (2 passes). The
design of the drum and conveyor also mean that it can handle material as short as 2 ¼”­long and down to 1/32”-thick! And, we are so sure of the heavy-duty construction and

5-year warranty!

Tough Structure

The JET 22-44 Pro-3 Drum Sander is built around a rigid
backbone. Massive 3”-diameter, thick walled steel posts provide
the main vertical support for this 385 lb. machine. A specially
engineered cast iron arm supports the drum assembly, insuring
accurate, repeatable sanding. The table and motor are also rigidly
supported on heavy gauge steel brackets.

Built around massive steel

columns, the JET 22-44
Pro-3 is as tough as it is

accurate.

Drum Sander exceptionally stable during use. The high quality
casters at the end of each leg feature
smooth rolling, non-marring
polyurethane tires. Each full swivel

caster has a foot operated lever that locks the swivel and wheel.

A full-width hinged shroud around the drum improves safety
while enhancing dust collection. A 4”-diameter port on the
outfeed side of the shroud lets you connect standard dust
collector hose (no adapters needed) to keep the shop clean and
extend the life of the abrasive.

Even the high end, full swivel

locking casters with their

polyurethane tires are standard

equipment.

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

1 phase, 230V (only)
power. This TEFC (totally
enclosed fan cooled) motor

is rated using a continuous
duty cycle to provide the clearest indication of its true power. This continuous duty cycle
design also means the motor will stand up to extended heavy usage.

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

Precision Drum

The JET 22-44 Pro-3 Drum Sander is built around our
heavy-duty 5”-diameter aluminum drum that has been
precision machined to insure straightness and balance. The
drum spins at 1600 RPM and is adjustable in height and
downward pressure to virtually eliminate snipe. That insures
