M3 All Weather doors
About the model
Dynaco M3 All Weather doors are designed for large openings with very high wind loads up to 110 km/h. Robust Dynaco M3 AW doors are installed in outdoor-to-indoor openings at warehouses, distribution centres and other specialised locations, including aircraft hangars, marine vessels, shipyards and mining facilities. Reliable Dynaco doors quickly isolate the opening, prevent draughts and help maintain the required indoor climate. This reduces facility operating costs.
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.
Energy-efficiency chart

Fast operation, opening speed - 1.4 m/s
Dynaco M3 All Weather high-speed doors open at 1.4 m/s and close at 0.6 m/s. For convenience, the equipment can be configured with two opening heights: one for pedestrians and low-profile equipment, and another for forklifts and reach trucks. This industrial door setting minimises the time the opening remains open and saves energy.
Sealing
High-speed doors seal the opening quickly and reliably. Even under high wind loads, the curtain provides reliable protection from draughts and dust.
Self-reinsertion
The Dynaco curtain contains no fragile elements. Even if accidentally hit by a vehicle, it does not deform and automatically reinserts itself into the guides during the next cycle. The design contains few wear-prone parts, so frequent specialist visits are not required, saving time and money.
