Maintaining proper combustion airflow is critical for your boiler, and the Weil-McLain 381-356-587 blower motor and housing assembly provides an integrated solution for the GV90+ series. This complete factory-authorized unit ensures that your heating system receives the precise air-to-fuel ratio required for safe, clean ignition and consistent thermal transfer.
This assembly utilizes a durable, direct-drive permanent-split capacitor (PSC) motor engineered specifically for the demands of continuous HVAC duty cycles. The blower housing is precision-molded to maximize static pressure efficiency, reducing mechanical strain while ensuring that exhaust gases are properly vented through the heat exchanger system.
Key System Performance Baselines:
- Motor Type: Industrial-grade permanent-split capacitor (PSC) for reliable, continuous-duty performance.
- Drive Configuration: Direct-drive design to minimize energy loss and reduce vibration.
- Build Quality: Precision-cast housing designed for high-heat durability and long-term structural integrity.
- Compatibility: Engineered exclusively for seamless integration with GV90+ S2 series boilers.
⚠️ Application Profile: Designed exclusively for the Weil-McLain GV90+ Series 2 hydronic boiler line. Installation should only be performed by a qualified HVAC technician to ensure proper combustion venting and seal integrity.
