Description
The A.J. Antunes 8021206060 is a genuine OEM air differential pressure switch from Antunes Controls’ SMD series, designed for reliable monitoring and control of low to medium differential air pressures in commercial HVAC, industrial, and mechanical systems. It senses changes in air pressure across two points and actuates control logic or safety circuits when the differential exceeds set thresholds. This switch features adjustable pressure settings from approximately 0.17 to 12.0 inches of water column (W.C.), making it suitable for a broad range of airflow monitoring and pressure sensing tasks. It uses a snap acting SPDT contact to provide dependable switching for control circuits.
