Information About 9371VO-BS-0046
The 9371VO-BS-0046 is a precision-engineered air pressure switch used in residential and light commercial furnace systems. It is typically installed within the furnace housing to detect negative pressure created by the inducer motor during operation. Built with a durable diaphragm and calibrated sensing mechanism, it ensures accurate pressure response at a set point of -1.50 inches of water column. This switch is compatible with a wide range of gas furnaces and integrates easily into existing HVAC control circuits, supporting safe ignition and proper venting conditions.
Key Features:
- Precise Pressure Calibration: Factory-set to -1.50" WC for accurate airflow verification
- Safety Monitoring Function: Ensures inducer motor operation before ignition sequence
- Durable Diaphragm Design: Provides consistent performance and long service life
- HVAC System Compatibility: Designed for use with various furnace models and brands
- Compact Form Factor: Allows easy installation within tight furnace compartments
- Electrical Switching Reliability: Maintains stable open/close response under load conditions
- High Sensitivity Response: Detects slight pressure variations for enhanced safety
- Corrosion-Resistant Materials: Suitable for long-term use in HVAC environments
- Quick Connect Terminals: Simplifies wiring and replacement procedures
- OEM Replacement Fit: Direct replacement for compatible MPL furnace systems
- Temperature Resistance: Operates reliably across standard furnace temperature ranges
The 9371VO-BS-0046 delivers the reliability and precision required for safe furnace airflow monitoring and combustion control.
