The quick running line of nonspring actuators open and close air dampers at top speed. According to the manufacturer - whether in heating or cooling circuits, ventilation, extraction, or VAV systems - these actuators ensure fresh air in paint rooms, laboratories, and other sensitive areas. They have a speed of 2.5 seconds for 90 degrees at 35 inch-pounds (in-lb) to 7 seconds for 90 degrees at 140 in-lb. The Multi-Function Technology (MFT) version is field-selectable for open/close and modulating. Features include rugged motors, NEMA 2 housings, automatic current reduction at standstill, and mechanical torque lock. Available for damper applications in rotating and linear versions, these actuators are load-independent over the entire specified operating range.
