It converts compressed air into rotational shaft output, making it suited for hazardous or washdown environments where electric motors are not appropriate. The motor delivers up to 2,500 RPM maximum speed with a minimum operating speed of 300 RPM, and produces 185 inch-pounds of torque. The keyed shaft measures 0.875 inches in diameter and 2.13 inches in length. Licensed HVAC technicians, industrial mechanics, and millwrights typically specify this motor for pneumatically driven equipment where variable speed and reversible rotation are required.\u003c\/p\u003e\u003cp\u003eThe 8AM-NRV-28A is designed for industrial and commercial pneumatic drive applications. Its reversible rotation capability allows the motor to change direction without additional mechanical components, which is useful in conveying, mixing, and positioning systems. The NEMA 145TC mount style provides a standardized footprint for direct-drive or coupled installations. The motor operates at a maximum working pressure of 100 psi and handles a maximum air flow of 175 cubic feet per minute, supporting consistent output across variable supply conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReversible shaft rotation with no additional components required\u003c\/li\u003e\n\u003cli\u003eKeyed shaft output at 0.875 inches diameter and 2.13 inches length\u003c\/li\u003e\n\u003cli\u003eNEMA 145TC mount for standardized, drop-in frame compatibility\u003c\/li\u003e\n\u003cli\u003eOperating speed range of 300 to 2,500 RPM for variable-speed applications\u003c\/li\u003e\n\u003cli\u003e185 inch-pounds of torque at rated conditions\u003c\/li\u003e\n\u003cli\u003e100 psi maximum working pressure with 175 CFM maximum air flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation air motor for equipment using NEMA 145TC frame-mount pneumatic drive assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright familiar with pneumatic drive systems. Shut off and lock out the compressed air supply before mounting or servicing the motor. Verify that supply air pressure does not exceed 100 psi and that the air supply is clean, dry, and lubricated per the manufacturer's requirements. Secure all fittings and confirm shaft alignment before restoring air pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 5 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2,500 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum RPM\u003c\/strong\u003e: 300 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque\u003c\/strong\u003e: 185 inch-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 100 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Air Flow\u003c\/strong\u003e: 175 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Length\u003c\/strong\u003e: 2.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: Keyed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Rotation\u003c\/strong\u003e: Reversible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Style\u003c\/strong\u003e: NEMA 145TC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 33 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: GAST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8AM-NRV-28A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GAST","offers":[{"title":"Default Title","offer_id":51720979513650,"sku":"8AM-NRV-28A","price":1060.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76fc8e856b275a3eefa5a5a8fd419fe2_8704b014-ff4c-4112-a064-c540e75a803e.jpg?v=1788571781","url":"https:\/\/voomisupply.com\/products\/gast-8am-nrv-28a-air-motor-5-hp-reversible-nema-145tc","provider":"Voomi Supply","version":"1.0","type":"link"}
