Cleveland Controls AFS-275-206 Sensing Switch
The Cleveland Controls AFS-275-206 is a pilot-duty adjustable differential pressure switch engineered for precision monitoring of positive, vacuum, or differential air pressure. This HVAC air pressure sensing switch is designed to detect airflow in various heating and ventilation applications, ensuring the blower or induces is functioning correctly before allowing the system to cycle. With an adjustable set point range of 0.05" w.c. ± 0.02" to 2.0" w.c., it provides the versatility required for fine-tuning system performance in high-efficiency furnaces and light commercial air handlers. The unit features a durable silicone diaphragm compatible with air and combustion by-products, housed in a rugged enclosure with a 1/2 PSI maximum pressure rating. Operating on 120V to 277VAC, this switch utilizes SPDT contacts to provide reliable signaling for safety interlocks or fan status monitoring. Contractors often reach for the AFS-275-206 as a dependable replacement for static pressure sensing in demanding environments.
Key Benefits for Technicians- Field Adjustable Range: Provides flexibility from 0.05" to 2.0" w.c., allowing for precise calibration on-site.
- High Compatibility: Designed for use with air and non-corrosive combustion gases that do not degrade silicone.
- Versatile Voltage Rating: The universal electrical rating accommodates 120V, 240V, and 277VAC systems without additional components.
- Reliable SPDT Contacts: Ensures clear signal transmission for both normally open and normally closed circuit requirements.
- Robust Construction: Engineered to withstand standard HVAC operating pressures up to 0.5 PSI.
How do I calibrate the set point for specific airflow requirements?
The set point is adjusted by turning the calibration screw located on the housing. Use a manometer to verify the exact inches of water column at which the switch closes to ensure the system meets manufacturer specifications.
What is the maximum operating temperature for the AFS-275-206?
This switch is typically rated for ambient temperatures ranging from -40°F to 180°F, making it suitable for most mechanical rooms and rooftop unit configurations.
Can this switch be mounted in any orientation?
For maximum accuracy and to maintain the factory calibration range, it is best practice to mount the diaphragm in a vertical plane. Horizontal mounting may shift the set point due to the weight of the internal components.
