Ao Smith cp1072l Air Compressor Motor 3/4 Hp 3600 Rpm 115/230V 56 Frame

Product Description

The AO Smith cp1072l is a 3/4 HP air compressor motor built for demanding shop and industrial applications. It runs at 3600 RPM and operates on 115 or 230 volts single phase power, giving technicians and tradespeople flexible installation options. The cp1072l fits a standard 56 frame configuration, which is one of the most common motor frame sizes used in compressor replacements and new builds. This makes sourcing a direct-fit replacement straightforward for HVAC technicians, plumbers, electricians, and general contractors who rely on air compressors daily. The motor draws 12.5 amps at 115 volts and 6.25 amps at 230 volts, keeping electrical load manageable across a wide range of service panels and wiring setups. An open drip proof enclosure protects internal windings from falling moisture and debris while allowing airflow to keep the motor cool during extended run cycles. The keyed shaft measures 5/8 inches in diameter and 1-7/8 inches in length, providing a secure mechanical connection to compressor pumps that require precise torque transfer without slippage. Reversible rotation means this motor can be configured to match the requirements of different compressor pump designs without special ordering. A service factor of 1 is rated for continuous duty at full nameplate load. Manual overload protection adds a layer of safety, cutting power if the motor draws excessive current due to a locked rotor, tight bearings, or other mechanical issues. Whether you are replacing a worn-out compressor motor on the job site or installing a new single-stage compressor system, the AO Smith cp1072l delivers reliable performance in a familiar, industry-standard package. It is a practical choice for anyone maintaining air-powered tools and equipment in commercial, residential, or light industrial settings.
