Replacement HVAC Part

This replacement air pressure switch is designed as a direct OEM equivalent for York HVAC systems and compatible equipment models. It functions as a close-on-fall type pressure switch with a 1.6 inches water column (WC) setpoint, automatically activating when air pressure drops to the specified threshold. This makes it ideal for controlling HVAC equipment operation based on duct pressure variations and system safety requirements. The switch features single pole normally open (SPNO) configuration and operates on 24VDC at 0.5A, making it compatible with standard commercial HVAC control systems. It utilizes a 3-wire connection setup for straightforward integration into existing installations. The unit is engineered to maintain reliable performance across demanding environmental conditions, with an operating temperature range of -40 Degrees F to 180 Degrees F (-40 Degrees C to 82 Degrees C), ensuring dependable operation in both heated and unheated spaces. This pressure switch is an essential component for HVAC system safety and efficiency, preventing equipment operation during abnormal pressure conditions and protecting against potential damage from restricted airflow. It is commonly used in commercial rooftop units, air handlers, and other HVAC applications where pressure monitoring is critical. The close-on-fall design allows the system to respond quickly when pressure drops, triggering appropriate equipment responses. As a direct replacement for original equipment, this switch ensures compatibility and proper system functionality without requiring modifications to existing ductwork or electrical connections. It is suitable for facility managers, HVAC contractors, and maintenance professionals seeking reliable OEM-equivalent components for their heating and cooling systems.
