High-speed door keeps cleanrooms sterile

Albany Door Systems developed a door based on the requirements of Good Manufacturing Practice (GMP): the Rapidroll Clean. Thanks to its close cooperation with the Fraunhofer Institute, it has achieved one of the highest possible quality levels: cleanroom class ISO 5 as per the European standard and GMP Class C.

The Rapidroll Clean high-speed door reduces air loss to a minimal 20 m³/h with a standard door size and constant positive pressure of 25 Pa. In production reality, certification in accordance with cleanroom class ISO 5 (as per EN ISO 14644–1) means that a maximum of 29 particles $5 µm will be found in 1 m³ of air, even during normal operation. This makes sterile production possible. Fast opening at a speed of up to 2.0 m/s and closing at up to 1.0 m/s reduces the strain placed on the filter in the cleanroom. The operator saves energy and the system becomes more efficient.

In order to ensure that the Rapidroll Clean fits in perfectly in the sterile clinical environment, the door structure has an easy-clean surface made from stainless steel (V2A). Finished without any overhang and sharp edges, with integrated cable routing and without a spring system, the door blocks possible contamination sources right from the start. The doors themselves are transparent, optimising the flow between individual workstations. The „Magic Switch“ allows for contactless opening and closing. An uninterruptible power supply in the roll cover ensures that the door continues to function even if there is a power cut.
