Model AMD-42V combines the functionality of an accurate airflow measuring station and a low-leakage vertical blade control damper into one compact assembly that measures and regulates airflow volumes to a target set point. This model comes standard with a modulating actuator and properly sized pressure transducer that output a signal proportional to cfm.

• Leakage 6 cfm per sq. foot at 4 in. wg or 3 cfm per sq. foot at 1 in. wg (110 cmh per m sq at 1 kPa or 55 cmh per m sq. at .25 kPa)
• Velocity: 300 to 3000 fpm (1.5 - 15.2 m/s)
• Temperature: -20°F to 180°F (-29°C to 82°C)
• Transducer Operating Temperature: 32°F to 140°F (0°C to 60°C)
• Airflow Monitoring Accuracy: 5% of reading
