Industrial JA2R140N NSMP

JA2R140N NSMP is a compact, industrial blower motor from A.O. Smith in the JA2R140N family, designed as an OEM replacement for small air‑handling and refrigeration fans. It is a 1/20‑horsepower, 208–230 V, 60 Hz, single‑phase motor that runs at 1,450 RPM and uses a 5/16‑inch shaft. The enclosure is open‑drip‑proof (ODP), and the frame diameter is about 3.3 inches, enabling installation in tight spaces. This NSMP variant is commonly used as a direct replacement in JA2R140N‑equipped blowers, including refrigeration fan assemblies and compact HVAC units, allowing retrofits without major mechanical changes. With standard voltage and modest power, it supports reliable airflow for cooling, ventilation, and light industrial processes where space constraints demand a small, efficient motor, while fitting common mounting patterns and electrical connections found in AO Smith and related OEM equipment.
