Trane SWT4488 Fan Status Switch
The Trane SWT4488 is a fan status switch engineered to verify airflow in HVAC air handling systems by sensing static pressure differential. With a 0.15″ W.C. static pressure setpoint, this switch provides dependable proof-of-fan operation, helping protect equipment and ensure system controls respond accurately to actual airflow conditions.
Key Features
- OEM Trane replacement fan status switch
- 0.15″ W.C. static pressure setpoint for precise fan proof detection
- Monitors airflow to confirm proper fan operation before enabling downstream system functions
- Designed for use in commercial and residential HVAC air handling applications
- Direct OEM replacement ensures fit, form, and function compatibility with Trane equipment
- Helps protect heating and cooling components from operating without adequate airflow
Application
The SWT4488 fan status switch is commonly used in Trane air handlers and rooftop units where proof of airflow is required before allowing heating, cooling, or ventilation sequences to proceed. By detecting the static pressure differential created by a running fan, the switch signals the control system that airflow is present — a critical safety and performance function in modern HVAC systems.
