Antunes 8023001235 SMD Air Differential Pressure Switch Preset at 0.30" WC

The Antunes 8023001235 is a factory-preset SMD (Sensitive Metal Diaphragm) air differential pressure switch designed for precise airflow monitoring in HVAC, boiler, and commercial kitchen applications. This non-adjustable switch is calibrated to activate at 0.30 inches of water column (WC), providing reliable pressure differential detection for combustion air proving, draft verification, and air handling system control.

Key Features:

• Preset actuation point of 0.30" WC for consistent, reliable operation
• SPDT (Single Pole Double Throw) snap-action electrical contacts rated at 10 amps
• Compact sheet metal construction for easy installation in tight spaces
• Monitors positive, vacuum, or differential air pressure
• CSA and ULC approved for safe operation in commercial and industrial settings
• Maximum surge pressure rating of 20" WC
• Wide ambient temperature range: -40°F to 170°F (-40°C to 77°C)
• Pilot duty rating: 125 VA at 125/277 VAC

The SMD series from Antunes Controls is known for its accuracy and reliability in demanding applications. This preset model eliminates the need for field adjustment, ensuring consistent performance right out of the box. Ideal for furnaces, boilers, burner management systems, and air handling units where precise air pressure monitoring is critical for safe and efficient operation.
