Running at 15,000 RPM on a 90 psi air supply, it draws 21 CFM through a 1\/4-inch inlet and delivers 0.25 hp at the pad. The through-handle exhaust directs spent air away from the work surface, keeping debris out of the operator's line of sight. The 2-fingered throttle provides responsive speed control during extended use. Licensed HVAC techs, pipefitters, metalworkers, and general contractors install this tool wherever a compact, high-speed abrasive tool is needed for tight-space surface work.\u003c\/p\u003e\u003cp\u003eThis sander is suited for residential and light commercial applications including weld prep, rust removal, paint stripping, and surface conditioning on metal, wood, and composite materials. The 3-inch pad size makes it well suited for confined areas and curved surfaces where a larger random-orbit or straight-line sander cannot reach. It ships with a full accessory kit including backing pad, surface prep discs, sanding discs in 80, 100, and 120 grit, and a spindle wrench, all stored in a heavy-duty carrying case.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15,000 RPM no-load speed for fast material removal and finish work\u003c\/li\u003e\n\u003cli\u003e3-inch (75 mm) pad size for tight-space and contour sanding\u003c\/li\u003e\n\u003cli\u003eThrough-handle exhaust keeps airflow directed away from the work surface\u003c\/li\u003e\n\u003cli\u003e2-fingered throttle for controlled, ergonomic operation\u003c\/li\u003e\n\u003cli\u003eShips with surface prep discs, 80\/100\/120 grit sanding discs, backing pad, and spindle wrench\u003c\/li\u003e\n\u003cli\u003eHeavy-duty carrying case included for tool and accessory storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3-inch (75 mm) PSA or hook-and-loop abrasive discs compatible with 1\/4-inch inlet pneumatic tools operating at 90 psi supply pressure.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eConnection to an air compressor requires a 1\/4-inch NPT air line fitting rated for at least 90 psi and a supply capable of sustained 21 CFM output. Verify the air supply is depressurized and the tool is disconnected from the air line before changing discs or the backing pad. Use eye protection and appropriate respiratory protection when operating any high-speed abrasive tool. No electrical lockout is required, but confirm the air line isolation valve is closed before servicing the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad Size\u003c\/strong\u003e: 3 inches (75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo-Load Speed\u003c\/strong\u003e: 15,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 21 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Pressure\u003c\/strong\u003e: 90 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Inlet Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 0.25 hp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Through Handle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrottle Type\u003c\/strong\u003e: 2-Fingered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.6 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHICAGO PNEUMATIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8941172021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO PNEUMATIC","offers":[{"title":"Default Title","offer_id":51540195442994,"sku":"8941172021","price":253.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ade8f02219f6efea90177973e787d9c5.jpg?v=1785848529","url":"https:\/\/voomisupply.com\/products\/chicago-pneumatic-8941172021-air-disc-sander-3in-15000-rpm","provider":"Voomi Supply","version":"1.0","type":"link"}
