Roll up door D-313 CL4

PVCclass 4indoor

Save energy with a breakthrough cleanroom solution
The Dynaco D-313 CL4 flexible high-speed roll-up door is designed to seal cleanrooms and controlled environments. It reduces air leakage, helps maintain stable pressure differentials and limits contamination risk while lowering air handling energy consumption.

Certified performance for ISO 14644-1 Class 4
The D-313 CL4 is certified for use in ISO 14644-1 Class 4 cleanrooms, making it the first high-speed cleanroom door validated for this class. Its pressure-resistant flexible PVC curtain and tight perimeter sealing support consistent airflow management in both overpressure and underpressure conditions, suitable for airlocks and critical zones.

Limit air exchange and reduce operational costs
High opening and closing speeds minimize door open time and reduce unnecessary air exchange. The door features low-friction side guides, a self-reinserting flexible curtain and a design with few wearing parts, resulting in low maintenance requirements and reliable operation.
