Description
The A.J. Antunes 8021202103 is a genuine OEM air differential pressure switch designed for HVAC and industrial systems that require reliable monitoring of low pressure changes. It senses when air pressure rises or falls beyond a preset threshold and actuates a control circuit using a single pole double throw (SPDT) contact, which makes it suitable for safety interlocks, airflow detection, and fan control functions.
Key Features
- Pressure Range: 0.17 – 1.0 inches of water column (W.C.), ideal for low pressure differential monitoring in ducts, blowers, or filters.
- Switch Type: SPDT (single pole, double throw) to provide reliable on/off control.
- Connection: 1/4″ compression fitting(s) for secure installation with tubing.
- Design: Compact, durable housing engineered for prolonged use in commercial HVAC environments.
