Cleveland Controls AFS-952-1-B Switch

The Cleveland Controls AFS-952-1-B is a heavy-duty adjustable differential pressure switch engineered for sensing air flow and pressure in rigorous commercial and industrial HVAC applications. Featuring a robust NEMA 4 enclosure, this unit provides superior protection against dust and moisture, making it ideal for rooftop units and harsh mechanical environments. The AFS-952-1-B offers a precise set point range of .05" to 12.0" w.c., allowing for versatile field adjustments across high-static systems. This differential air pressure switch utilizes a silicone diaphragm and SPDT contacts to ensure reliable signal transmission for fan proving, filter monitoring, and damper control logic. Designed for HVAC pressure monitoring, the unit integrates seamlessly with commercial air flow sensors, providing the durability needed for critical air proving sequences. Contractors rely on this Cleveland Controls air switch for its high-impact housing and consistent B-type mounting configuration, ensuring stable performance in high-demand pneumatic circuits.

• Wide Operating Range: Adjustable from 0.05" to 12.0" w.c. to accommodate various static pressure sensor requirements.
• Environmental Protection: NEMA 4 rated housing prevents ingress in outdoor or wash-down applications.
• Field Reliability: High-performance silicone diaphragm maintains calibration under fluctuating temperature conditions.
• Flexible Mounting: The B-mount design facilitates quick replacement in existing air pressure switch brackets.
• Electrical Versatility: SPDT switch configuration supports both normally open and normally closed sequences.

What is the maximum pressure rating for the AFS-952-1-B?
This switch is rated for a 0.5 psi maximum pressure surge, ensuring the diaphragm remains intact during sudden system startups.

Can this switch be used for liquid pressure sensing?
No, the Cleveland Controls AFS-952-1-B is specifically designed for air and non-combustible gases; liquid media will damage the internal components.

Does the NEMA 4 rating allow for direct outdoor installation?
Yes, the enclosure is designed for wet environments, though a weather shield is recommended in areas with extreme ice or snow buildup to ensure the vent remains clear.
