The Cleveland Controls FS-751-385 is a precision air flow switch engineered for reliable detection of airflow in HVAC, combustion, and ventilation systems. Featuring a Single-Pole Double-Throw (SPDT) switching action, this unit is factory-set to operate on a pressure rise of .05″ ±.02″ w.c., making it ideal for low-differential pressure sensing applications where accurate airflow confirmation is critical.
Key Features
- SPDT switching action for versatile control circuit integration
- Fixed setpoint: operates on pressure rise at .05″ ±.02″ w.c.
- Wide voltage range: 120–277Vac for compatibility with commercial and industrial systems
- Barbed connections for quick, secure tubing attachment
- Maximum operating pressure: ½ PSI (0.5 PSI)
- Compatible with air or combustion by-products that will not degrade silicone
Application
The FS-751-385 is well-suited for proving airflow in air handling units, furnaces, burner systems, and ventilation equipment. Its silicone-compatible media rating makes it appropriate for use in combustion exhaust sensing applications where standard rubber components may degrade over time. The barbed port connections simplify field installation with standard flexible tubing.
