Sterling 11J13R01661 Fire Stat/Air Flow Switch for HVAC Systems

The Sterling 11J13R01661 is a combination fire stat and air flow switch designed for HVAC heating systems. This dual-function safety device monitors both air temperature and air flow to protect heating equipment from dangerous operating conditions.

Key Features:

• Dual-function design combines fire stat high limit control with air flow proving switch
• Monitors air temperature in ductwork to prevent overheating conditions
• Detects changes in air movement to ensure proper system operation
• Automatically triggers system shutdown when temperature exceeds preset limits or air flow is insufficient
• Designed for use with Sterling gas-fired unit heaters and HVAC systems
• Critical safety component that prevents equipment damage and potential fire hazards

This switch is commonly used in commercial and industrial heating applications where reliable safety monitoring is essential. It ensures that heating equipment operates only when adequate air flow is present and shuts down the system before dangerous temperature levels are reached.
