Motor, reduction gear and folding arm in one compact system.
Stable mechanical drive
The built-in motor drives a reduction gear set, extending or retracting the folding arm to open and close the sash smoothly.
Controlled travel
Integrated limit switches stop movement at the set end position to help prevent over-travel and mechanical damage.
Fire-linkage response
When connected to a compatible AOV controller, the opener automatically drives the smoke vent open after receiving a fire signal.
