Ingersoll Rand 4151-5 Random Orbital Air Sander | 3/16" Orbit Diameter | 5" Pad Diameter | 12000 RPM | Rear Exhaust

Built for body shops, repair bays, fabrication areas, and finishing work, the Ingersoll Rand 4151-5 Random Orbital Air Sander delivers controlled sanding performance in a compact 5" pad diameter configuration. Its 3/16" orbit diameter provides a balanced sanding pattern for paint prep, filler leveling, fiberglass work, and finish sanding, while the 12,000 RPM motor helps produce a smooth, swirl-free finish when paired with the correct abrasive disc.

This vacuum-ready, low-vibration sander connects to compatible central or portable vacuum systems to help extract dust and particles through and around the pad. By helping keep foreign matter away from the motor and work surface, the 4151-5 supports cleaner sanding, smoother operation, and better finish control during repeated shop use.

FAQs:

• Q: What is the benefit of the 5" pad on the Ingersoll Rand 4151-5?
  A: The 5" pad gives the tool a smaller sanding footprint than a 6" sander, which can be useful for spot repair, contour work, smaller panels, and more controlled sanding areas.
• Q: What does the 3/16" orbit mean?
  A: The orbit diameter is the size of the pad’s circular sanding motion. A 3/16" orbit gives a balanced sanding pattern for paint prep, body filler work, and finishing without being overly aggressive.
• Q: Is the 4151-5 vacuum ready?
  A: Yes. This model is vacuum ready and can connect to compatible central or portable vacuum systems to help remove dust and particles during sanding.
• Q: What abrasive discs should be used with this sander?
  A: Use 5" abrasive discs that match the vinyl pad face and the sanding task. Replacement pads should also match the 5/16"-24 output thread and be suitable for the tool’s 12,000 RPM free speed.
• Q: What air setup is required for this tool?
  A: The 4151-5 uses a 1/4" NPT air inlet, requires a 5/16" minimum hose size, and has an average air consumption of 8 CFM. Use an air supply that can maintain steady airflow during continuous sanding.
