The NBK-20518 Blower Motor (230V, 50/60 Hz, 1/10 HP, 1 Speed) is a compact, durable shaded-pole centrifugal blower motor designed as a direct aftermarket replacement for air movement in HVAC ventilation, draft inducers, small centrifugal blowers, exhaust fans, wood/pellet stove convection or combustion blowers, outdoor boilers, or compatible OEM applications. This motor powers the centrifugal wheel to deliver strong, consistent airflow (559 CFM), supporting combustion air supply, convection heat distribution, exhaust venting, or general circulation—ensuring efficient burning, even heat output, and reliable performance in residential heating systems like wood stoves, pellet stoves, or light commercial/outdoor boiler setups on 230V circuits.
As a premium equivalent, it cross-references and fits seamlessly as a replacement for:
- Dayton 1TDT3 (primary OEM cross-reference), 4C870
- Fasco 7008-6481, 50769-D230, 50769D230
- And compatible models from Grainger/Dayton, Fasco, or systems using this 230V shaded-pole centrifugal design (popular in high-airflow stove blowers, small draft/vent fans, or aftermarket upgrades)
