The NBK-20515 Blower Motor (230V) is a compact, reliable 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 generate focused, high-velocity airflow (typically low-to-mid CFM range suited for venting/draft in equivalents), supporting combustion air supply, exhaust venting, draft creation, or general circulation—ensuring proper burning, safe operation, and efficient 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 1TDR4 (primary OEM cross-reference)
- Fasco 7063-7019, B45227-2 (and related variants)
- And compatible models from Grainger/Dayton, Fasco, or systems using this 230V shaded-pole centrifugal design (popular in stove blowers, small draft inducers, or aftermarket upgrades)
Key specifications include fractional HP (typically ~1/30 to 1/20 HP range for these compact units), 230V single-phase 50Hz / 60Hz, amp draw (~0.4 / 0.36), high RPM (~1380–1620 RPM), airflow suited for focused venting/draft (265 CFM), CWSE rotation (common), sleeve bearings, compact 3.3" diameter frame, thermally protected, side mounting tabs or all-position mounting, and extended leads—no capacitor required (shaded-pole type). Ideal for low-HP, high-RPM applications in tight spaces or 230V systems.
Installation is plug-and-play (match existing wiring, mounting tabs, and wheel if assembly), making it a practical choice for HVAC technicians, stove service pros, or homeowners fixing reduced airflow, noisy motors, poor draft/venting, weak combustion, or performance issues—especially useful in Wisconsin homes with wood/pellet stoves or outdoor boilers on 230V circuits during harsh winters. With durable, quiet construction for long-lasting reliability, the NBK-20515 delivers OEM-comparable performance at an affordable price—stocked and shipped fast.
