Chicago Pneumatic 8941172001 Air Random Orbital Sander

Product Description

The CHICAGO PNEUMATIC 8941172001 is a right angle air-powered random orbital sander built for pneumatic finishing work in automotive, fabrication, and metal prep applications. The sander accepts a 2-inch round hook-and-loop backing pad and runs at up to 15,000 OPM, delivering consistent swirl-free surface finishing. It requires a compressed air supply at 90 psi with a minimum inlet size of 0.375 inches and consumes 21 CFM at rated speed. The right angle head design allows access to tight panels and recessed surfaces that straight-line sanders cannot reach. Licensed tradespeople and professional finishing technicians are the primary installers of this tool.

This sander is suited for light material removal, surface prep, and fine finishing on metal, body filler, and primer surfaces. The right angle configuration makes it practical for automotive bodywork, metal fabrication shops, and general surface preparation where a low-profile tool is needed. The hook-and-loop pad system allows fast abrasive disc changes without adhesive backing, reducing downtime between grits. It operates on a standard shop air system capable of sustaining the required 21 CFM flow rate at 90 psi.

Key Features

Compatibility

Designed for use with standard 2-inch round hook-and-loop sanding discs on shop air systems capable of supplying 21 CFM at 90 psi through a minimum 0.375-inch air hose.

Installation Notes

Installation and operation should be performed by personnel familiar with pneumatic tool safety practices. Ensure the air supply is depressurized and the tool is disconnected from the air line before changing abrasive discs or performing any maintenance. Verify the air hose and fittings meet or exceed the minimum 0.375-inch inside diameter requirement to maintain proper airflow at operating pressure. Follow applicable workplace safety standards and the manufacturer's operating manual for safe speed and pressure limits.
