Ingersoll Rand 4151 Random Orbital Air Sander is a vacuum-ready pneumatic sander designed for smoothing and finishing applications where controlled orbital motion and high rotational speed are required. The manufacturer specifies a 12,000 RPM maximum free speed, 3/16-inch (5 mm) orbit diameter, and 6-inch (150 mm) pad diameter. Its 0.2 HP pneumatic motor and random orbital action are designed to produce a high-quality finish while the vacuum-ready configuration allows connection to central or portable vacuum systems.
The 4151 uses a vinyl-faced pad with a short shroud and rear exhaust. The manufacturer lists a 1.92 lb (0.87 kg) weight, 7.48-inch (190 mm) length, 1/4-inch NPT air inlet, and 8 CFM average air consumption. A 5/16-inch (8 mm) minimum hose size is specified, helping buyers properly size the compressed-air connection for the tool.
