Multiple interconnected D-313 Cleanroom CL4 doors, the world's only high-speed door certified for ISO 14644-1 Class 4 environments, ensure superior sealing, pressure stability, and uninterrupted operations at a pharmaceutical site.

Long-standing Dynaco partner Kolbud has successfully installed multiple Dynaco D-313 Cleanroom CL4 high-speed doors in an airlock configuration for a pharmaceutical client. Technically demanding and refined in every detail, this project is a clear demonstration of why cleanroom environments in the pharmaceutical, biotech, and life sciences sectors require door solutions that leave absolutely no room for compromise.

 

The world's only high-speed door certified for ISO 14644-1 Class 4 cleanrooms

The Dynaco D-313 Cleanroom CL4 holds a unique position on the market: it is the only high-speed door in the world certified for use in ISO 14644-1 Class 4 environments. This is not a minor product distinction. It is a major technological breakthrough that sets a new benchmark in cleanroom door design, and it means pharmaceutical facilities using the D-313 Cleanroom CL4 benefit from a level of certification no competing product can currently match. For environments where contamination control, sterile conditions, and regulatory compliance are non-negotiable, this makes the choice straightforward.

Interconnected airlock configuration for continuous pharmaceutical operations

The D-313 Cleanroom CL4 doors were installed in an interconnected airlock setup, enabling precise control of transitions between zones with different atmospheric requirements. This configuration maintainsstable pressure levels, whether in overpressure or underpressure conditions, while ensuring continuous flow of personnel and materials. The result is reduced waiting times, optimized throughput, and no compromise on the integrity of the controlled environment.

Superior sealing, energy efficiency, and minimal maintenance

The door's pressure-resistant flexible PVC curtain delivers superior sealing performance, keeping clean air inside and contaminants outside at all times. Its high opening and closing speed minimizes air exchange between zones, directly reducing energy consumption and cleanroom operating costs. Designed with low-friction side guides, a self-reinserting curtain, and a minimum of wearing parts, the D-313 Cleanroom CL4 requires very little maintenance, ensuring maximum uptime in a sector where every minute of production continuity counts.

Thanks to Kolbud for this technically advanced installation and for consistently delivering the level of expertise and quality that the most demanding pharmaceutical environments require.

Summary

Kolbud installed multiple interconnected Dynaco D-313 Cleanroom CL4 high-speed doors in a pharmaceutical airlock. As the world's only high-speed door certified for ISO 14644-1 Class 4 environments, this solution delivers superior sealing, stable pressure control, and energy efficiency, ensuring safe, compliant, and uninterrupted operations in a demanding cleanroom environment.
