About the model
Dynaco M3 Power doors are designed for large openings separating indoor areas from the outdoors. These reliable doors are designed for high wind loads up to 90 km/h. The maximum size of the robust M3 Power doors is 9,000 x 5,500 mm. They are suitable for industrial facilities and plants manufacturing oversized equipment, mining operations and warehouses in large shopping centres.
Unique technologies
Push-Pull technology
The motor pulls the curtain up when the door opens and pushes it down when the door closes.
The doors are sealed around the entire perimeter
Thanks to their excellent sealing, DYNACO high-speed doors withstand wind loads up to Class 5 under European standard EN 12424.
Side guide and flexible side toothed rack
The door curtain is secured at the sides in specially designed guides that fit tightly against the curtain's side edge. Gaps and openings are eliminated.
Safe for vehicles and pedestrians
The DYNACO door design contains no rigid or heavy elements. Even if the curtain descends onto a vehicle or pedestrian, it will not cause harm and will automatically start moving upward.

Doors for large openings
The maximum size of M3 Power high-speed doors is 9,000 x 5,500 mm. Installation requires little space: the upper cover is only 500 mm high and the side guides are 150 mm wide.
Automatically recover after impact
An important difference between Dynaco doors and others is that a curtain knocked out accidentally does not require repair. On impact it leaves the guides and automatically reinserts itself during the next cycle, preventing downtime and saving on rapid-door repairs.
Reliable wind protection
Dynaco high-speed curtains prevent draughts and operate correctly even under high wind loads up to 90 km/h. Dust and insects cannot enter when the doors are closed.
