Motorized Damper handles air flows from 15-4,000 cfm.
Air Flow Dampers

Motorized Damper handles air flows from 15-4,000 cfm.

With IRIS-M motorized damper, minimum and maximum airflows are measured within ±5% by using product's pressure port and altered by means of actuator adjustment screws. Unit varies airflow in response to 0-10 Vdc or 4-20 mA signal to control temperature, humidity, or ventilation rate. External switch fully retracts damper for duct cleaning. Made from galvanized steel with neoprene seals, 6...
