Sterling HVAC 11J13R01661 Fire Stat / Air Flow Switch

Description

Sterling HVAC 11J13R01661 Fire Stat / Air Flow Switch Overview

The Sterling HVAC 11J13R01661 is a dual-function safety control combining a fire stat and an air flow switch in a single unit. Designed for use in commercial and industrial HVAC air handling applications, this component provides critical system protection by monitoring both high-temperature conditions and confirming adequate airflow — two of the most essential safety checks in any forced-air system.

Fire Stat Function

The integrated fire stat monitors supply or return air temperatures and opens the control circuit when temperatures exceed a safe threshold. This helps prevent the spread of smoke and fire through ductwork by shutting down the air handling unit under dangerous conditions, supporting building safety and code compliance.

Air Flow Switch Function

The air flow switch verifies that adequate airflow is present before allowing the system to operate. By confirming proper duct pressure differential, it protects heating and cooling equipment from operating without sufficient airflow — preventing overheating, equipment damage, and unsafe conditions.
