It was more than 30 years ago that EFAFLEX invented the high-speed spiral door. The spiral guidance system ensures the doors curtain is not wound on a shaft, but kept at a spacing during operation. Thanks to this mechanical principle, the spiral doors from EFAFLEX operate exceptionally quietly, are almost wear-free and extremely fast! The EFAFLEX “Next Generation” includes four door types available in three variants—Premium, Eco, and Basic—all based on a single concept. Each door can be individually configured and customized using a modular system, resulting in twelve different doors tailored to a wide range of needs and applications.
