Antunes 8221210034 Air Differential Pressure Switch 0.05-1.0 W.C. SPDT

The Antunes 8221210034 is an SPDT (Single Pole Double Throw) air differential pressure switch designed for HVAC and industrial pressure monitoring applications. This SML Series switch features an adjustable set point range from 0.05 to 1.0 inches water column, making it ideal for detecting low air pressure differentials in combustion safety systems, air flow monitoring, and filter status applications.

Key Features:

• Adjustable pressure range: 0.05 to 1.0 inches W.C.
• Maximum operating pressure: 30 inches W.C.
• 1/4 inch compression fitting connections for easy installation
• SPDT contact configuration for versatile switching applications
• Automatic reset functionality
• Sensitive diaphragm design for accurate pressure detection

The compression fitting connections eliminate the need for threading or welding, simplifying installation while providing reliable, leak-free connections. This pressure switch is commonly used in commercial heating equipment, boilers, ventilation systems, and industrial process control applications where precise air pressure monitoring is critical for safe and efficient operation.
