Bard 8406-079BX Switch
The Bard 8406-079BX Switch is an OEM differential pressure switch engineered for precision air pressure monitoring in Bard HVAC systems. This .63" WC pressure switch is a critical component for verifying airflow proving and static pressure, ensuring your wall-mount units or packaged systems operate within safe parameters. Field-proven for reliability, the 8406-079BX features a factory-set trip point of .63 inches Water Column, making it an essential replacement part for maintaining system efficiency and protecting the blower motor and heat exchanger from low-airflow conditions. Designed with high-durability housing, this Bard replacement part integrates seamlessly into existing safety circuits to provide immediate response to pressure deviations, preventing equipment damage and ensuring long-term HVAC system performance. Whether you are troubleshooting air filter restrictions or fan speed issues, this switch provides the accurate differential sensing required by professional contractors for high-stakes commercial and residential applications.
Key Benefits- OEM Compatibility: Guaranteed fit and function for specific Bard wall-mount and packaged HVAC units.
- Precise Pressure Sensing: Calibrated at .63" WC for accurate differential air pressure detection.
- System Protection: Acts as a limit control to shut down operations during abnormal airflow or filter blockage.
- Rugged Construction: Built to withstand the vibrating environments of industrial HVAC cabinets for extended service life.
- Simplified Integration: Designed for standard mounting and wiring in Bard safety circuits.
Is the 8406-079BX field-adjustable?
This specific model is factory-set to .63" WC to match Bard's original equipment specifications for safety and performance; however, checking the unitās service manual for specific setup requirements is recommended.
Will this switch help with air filter monitoring?
Yes, the Bard 8406-079BX is commonly used to detect the pressure drop across air filters, alerting the system when a filter is dirty enough to restrict required airflow.
Does the "BX" suffix change the switch specifications?
No, the "BX" suffix on Bard parts typically denotes bulk or retail packaging and does not alter the technical performance or compatibility of the 8406-079 base part number.
