AIR SWITCH (MRD-12-01039-08)

The Air Switch is an important safety and control device in transport refrigeration systems. It detects airflow or air pressure changes within the system to help ensure proper operation and prevent damage.

• Monitoring Airflow: The air switch senses whether there is adequate airflow through components such as the condenser or evaporator fans.
• Protecting System Components: If airflow drops below a safe threshold due to fan failure or blockage, the switch can trigger a shutdown or alarm to prevent compressor damage or overheating.
• Control Function: It may also be used to enable or disable certain system functions based on detected air pressure or flow conditions.
• Enhancing Safety: By ensuring fans and air circulation are operating correctly, the air switch helps maintain stable temperatures and system reliability.
• Diagnostic Tool: Activation of the air switch alert can help technicians quickly identify issues related to airflow interruptions or fan malfunctions.

In summary, the air switch is vital for monitoring airflow in transport refrigeration systems, providing safety and control to protect the equipment and maintain efficient cooling.
