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.

Features & Benefits

  • Safe Soft Edge Design: Provides employees and equipment with superior protection against accidents and maintenance associated with hard-edge doors (Safest door in the industry).
  • Self Re-insertion: No manual intervention required.
  • Wind load tested to Class 1 (EN Standards); Withstands pressures up to 50 MPH (1.211 in. of water) (301.6 Pa) for D-411, and Class 2 (EN Standards); Withstands pressures up to 60 MPH (1.8 in. of water) (448 Pa) for the D-421. The side guides incorporate spring-loaded and pivoting action which deflect under pressure.
  • The door’s curtain incorporates a patented wind retention design which uses side guides formed of galvanized steel with UHMW inner side guides. 
  • Encapsulated zipper guide assembly:  The resulting tight seal (which eliminates wind ribs thus reducing vibration, noise, and dramatically increases user safety), combined with a mobile top seal & soft bottom, provide a virtually perfect seal, unlike open-channel designs (No blade or brush system to wear or replace).
  • Curtain Material: Reinforced 27 oz. PVC material with sealed bottom edge. Available in 9 standard colors. 15” full-width banner window included as standard
