Cleveland Controls AFS-271-396 Air Flow Switch
The Cleveland Controls AFS-271-396 Air Flow Switch is a professional-grade differential pressure switch designed for precise monitoring in HVAC and industrial process ventilation. This unit features an adjustable set point range from .05" ± .02 to 2.0" w.c., allowing for fine-tuned calibration across a variety of airflow velocities. Engineered with a Normally Open (NO) contact configuration, the AFS-271-396 is optimized for safety interlock circuits, proving fan operation or filter status before allowing downstream equipment to energize. Its rugged construction is rated for up to 1/2 PSI maximum pressure and is compatible with air and combustion byproducts that do not degrade its internal silicone diaphragm. With a broad electrical rating of 120-277VAC, this switch integrates seamlessly into complex control loops for air handlers, chillers, and industrial exhaust systems, ensuring reliable proof-of-flow detection in demanding environments.
Key Benefits for Contractors
- Broad Set Point Flexibility: The adjustable range of 0.05 to 2.0 inches water column handles everything from low-velocity exhaust to high-static duct monitoring.
- High Voltage Compatibility: Field-ready for 120V, 208V, 240V, and 277V circuits, reducing the need for multiple SKUs on the service truck.
- Industrial Durability: Designed to handle combustion byproducts and non-corrosive gases without compromise to the switching mechanism.
- Critical Safety Logic: The Normally Open configuration provides a reliable "proof of air" signal essential for burner circuits and electric heater banks.
- Easy Installation: Features standard 1/4" compression or barbed fittings for rapid pressure line connection in the field.
Common Questions
What is the maximum pressure limit for the AFS-271-396?
This switch is rated for a continuous maximum pressure of 0.5 PSI. Exceeding this limit may damage the internal silicone diaphragm and affect the accuracy of the set point.
Can this switch be used to monitor flue gas?
Yes, the Cleveland Controls AFS-271-396 is compatible with air and combustion byproducts, provided they do not contain chemicals that degrade silicone. It is frequently used in industrial ventilation and boiler applications.
Is the set point fixed or adjustable?
The set point is fully adjustable. Technicians can field-calibrate the switch to trip anywhere between its .05" and 2.0" w.c. operating window to match specific system requirements.
