Dynaco High-Speed door D-313 CL4 Cleanroom Door

High-speed cleanroom door certified for use in ISO 14644-1 Class 4 environments

The Dynaco D-313 CL4 is a high-performance, high-speed roll-up door specifically developed for critical cleanroom environments. It is the world’s first high-speed cleanroom door certified for use in ISO 14644-1 Class 4 environments, making it the reference solution for applications with the most stringent contamination control requirements.

Thanks to its ultra-compact design, the D-313 CL4 requires minimal installation space and is ideal for interlocks, airlocks and cleanroom transitions where space, hygiene and pressure control are critical.

The door features an exceptionally tight sealing system that minimizes air leakage, maintains stable pressure zones and significantly reduces particle ingress. Independent testing by the Fraunhofer Institute confirms its suitability for use in ISO Class 4 cleanrooms, ensuring compliance with the highest cleanroom requirements.

The pressure-resistant flexible PVC curtain supports both overpressure and underpressure environments and effectively blocks dust, airborne particles, humidity variations and temperature differences.

Designed for intensive operation, the D-313 CL4 is equipped with low-friction side guides, a self-reinserting flexible curtain and a motor fully integrated in the drum. The curtain contains no rigid elements, ensuring maximum safety for users and equipment while keeping maintenance requirements to a minimum.

The Dynaco D-313 CL4 is the ideal solution for pharmaceutical, biotech, chemical, electronics, semiconductor, medical and high-tech cleanroom environments where reliability, compliance and contamination control are critical.
