Dynaco M3 High Speed Door

High Speed Doors


We've designed the exterior DYNACO All Weather M3 high performance door with a superior seal, making the door wind resistant up to 110 MPH.

Protect against wind, precipitation, dust and extreme temperatures while saving energy with a tight seal around the full perimeter of the door. The high-speed open/close mechanics optimize traffic and logistics in and out of your building.


Our patented push-pull drive technology operates without a ballast, pushing down the high performance door even under a strong headwind.

The DYNACO All Weather M3 roll up door keeps your people and equipment safe with a curtain free of rigid elements. Our maintenance-friendly curtain design avoids downtime by reinserting itself into the side guides after an open and close cycle should it become dislodged.
