Gravity-Driven

Low Friction Technology

High performance door designed to withstand air pressure differences

Gravity door with enhanced wind resistance

Dynaco D-4 Series doors are a new and enhanced design providing better environmental control, efficiency, footprint, wind load, and lower life cycle cost than competitive products. Appropriate for interior or exterior applications, this wind load roll up door will resist static wind pressure to 9.4 lbs./ft2. These next generation doors incorporate unique DYNACO innovations including: “soft curtain” technology, fully automatic re-insertion, and low friction encapsulated edge retention.

Next-generation safety, speed and simplicity

The D-4 Series high-performance doors provide a superior gravity-assisted solution in terms of safety, speed, and simplicity because they do not require solid components in the door curtain. The fabric door travels fast, and safely responds to obstructions. The patented re-introduction blocks will reset the door without manual intervention should a lateral impact separate the door from the side-guides.
