It delivers 90 ft\/lb of torque at up to 9,500 RPM with 1,400 impacts per minute, making it effective for fastener removal and installation on mid-range fastener sizes. The butterfly handle design keeps the tool compact and maneuverable in tight spaces. It requires a 90 psi air supply and consumes 13 CFM, so pairing it with an adequately sized compressor and supply line is essential for consistent performance. At 2.53 pounds, it is light enough for extended use without significant fatigue.\u003c\/p\u003e\n\u003cp\u003eThis wrench suits residential and commercial maintenance tasks where a mid-torque, compact air tool is appropriate. Typical applications include brake service, suspension work, HVAC equipment assembly, and general fastener work on mechanical systems. The rear exhaust directs airflow away from the work area, which is useful in confined spaces. It is commonly used by automotive technicians, HVAC service technicians, plumbers, and general maintenance tradespeople who carry air tools as part of a standard kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch drive with friction ring retainer for secure socket retention\u003c\/li\u003e\n  \u003cli\u003e90 ft\/lb torque output at 90 psi operating pressure\u003c\/li\u003e\n  \u003cli\u003e9,500 RPM and 1,400 impacts per minute for fast fastener cycling\u003c\/li\u003e\n  \u003cli\u003eButterfly handle style for compact grip and easy one-hand control\u003c\/li\u003e\n  \u003cli\u003eRear exhaust routes airflow away from the operator and work surface\u003c\/li\u003e\n  \u003cli\u003eLightweight at 2.53 pounds for reduced fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/8 inch drive impact sockets. Requires a minimum 3\/8 inch hose and a 1\/4 inch NPTF or NPT air inlet fitting. Compatible with compressed air systems supplying a steady 90 psi and at least 13 CFM at the tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed or experienced technician should verify that the air supply system delivers the required pressure and flow before connecting the tool. Always depressurize the air line before attaching or detaching the wrench from the hose. Use thread sealant appropriate for pneumatic connections on the NPT fitting, and confirm the minimum 3\/8 inch hose ID is maintained from the compressor to the tool to avoid pressure drop. The 108 dB sound level requires appropriate hearing protection per applicable workplace safety regulations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 90 ft\/lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeed\u003c\/strong\u003e: 9,500 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImpacts Per Minute\u003c\/strong\u003e: 1,400 BPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Pressure Required\u003c\/strong\u003e: 90 psi (6.30 bar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 13 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/4 inch NPTF \/ NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hose Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Butterfly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Rear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRetainer Type\u003c\/strong\u003e: Friction Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Style\u003c\/strong\u003e: Compact\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDecibel Rating\u003c\/strong\u003e: 108 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.53 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 8941077220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO PNEUMATIC","offers":[{"title":"Default Title","offer_id":51542014886194,"sku":"8941077220","price":296.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a24ccfb6ced00c7a15d6840474a26258.jpg?v=1785889642","url":"https:\/\/voomisupply.com\/products\/chicago-pneumatic-8941077220-air-impact-wrench-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
