Cleveland Controls AFS-531-328 Switch
As a seasoned contractor, you know that proving fan status and monitoring pressure drops requires a switch that doesn't drift. The Cleveland Controls AFS-531-328 is a professional-grade differential air pressure switch designed for precision in HVAC, energy management, and industrial ventilation. Featuring a field-adjustable setpoint range of 0.05" to 1.0" w.c., this unit allows for fine-tuning to meet specific economizer or proving switch requirements on-site. The SPDT snap-acting switch electrical rating of 5A at 240VAC provides reliable signal feedback for combustion air proving or filter status monitoring. Encased in a durable plated housing with a silicone diaphragm, this low pressure switch ensures long-term stability even in demanding environments. For accurate airflow detection, ensure the diaphragm is mounted in a vertical plane. With its standard 1/4" compression fittings and 1/2" conduit entry, the AFS-531-328 integrates seamlessly into existing low-voltage or line-voltage control loops without the need for specialized adapters.
Key Benefits for the Job Site:- Precise Pressure Range: Field-adjustable from 0.05 to 1.0 inches of water column for versatile application across multiple furnace and air handler models.
- Rugged Construction: Built with a plated housing and high-reliability diaphragm to withstand 100,000 cycles at 0.5 psi.
- Versatile Mounting: Integral foot bracket with 3/16" diameter holes allows for stable installation in vibration-free zones.
- Flexible Connectivity: Dual sample line connections accept 1/4" OD tubing via ferrule and nut compression for a leak-proof seal.
How do I calibrate the setpoint on the AFS-531-328?
To adjust the actuation point, use the adjustment screw located under the enclosure cover. Turn several times from the lowest point to engage the calibration spring until the desired switching pressure is reached.
What is the proper mounting orientation for this air flow switch?
For the lowest specified setpoint accuracy, always mount the switch with the diaphragm in a vertical plane. Avoid mounting with the sample line connectors facing upward to prevent moisture accumulation.
Can this switch be used for both positive and negative pressure?
Yes. To sense positive pressure, connect to the LOW side while leaving the HIGH side open to atmosphere. For negative pressure, connect to the HIGH side and leave the LOW side open.
