FM Series Chain Actuator
Centered chain orientation actuator
- Ideal for smart buildings; integrates with building and home automation systems
- Low voltage DC motors are energy efficient
- Multiple actuators may be linked for simultaneous operation of multiple windows
- Push/Pull Force up to 700 N (158 lbf)
- Opening distance ranges from 501mm to 800mm approx.
- UL Recognized

Applications
- For automation of awning or hopper windows, skylights, or curtain wall vents.
- For commercial, institutional and residential projects, including schools, universities, municipal buildings, offices, gymnasiums, homes, condos, and more.
- Natural Ventilation systems, such as operable windows and skylights, save energy and lower operating costs by reducing air conditioning and heating use.
- LEED credits for green building projects can be earned under Indoor Environmental Quality for Natural Ventilation, Daylighting and Views.
- Smoke Evacuation systems reduce smoke, heat and casualties during a fire; AFI actuators are SHE certified.
