Bard 8406-100BX 0.73" W.C. Differential Pressure Switch

The Bard 8406-100BX is a differential pressure switch designed for reliable pressure monitoring in HVAC systems. This switch operates at a set point of 0.73 inches water column (W.C.) and features an SPDT (Single Pole Double Throw) configuration for versatile control applications.

Key Features:

• 0.73" W.C. differential pressure rating for precise air pressure monitoring
• SPDT configuration provides flexible switching capabilities
• Designed for use in air handling units, furnaces, and ventilation systems
• Monitors pressure levels to ensure optimal system performance
• Helps prevent equipment damage caused by pressure fluctuations
• Replaces older models 8406-100 and 8406-080

This pressure switch is commonly used in wall-mounted HVAC units and packaged heating and cooling systems. It measures air or gas pressure and automatically opens or closes an electrical circuit when pressure conditions change, ensuring safe and efficient operation of HVAC equipment.
