High-speed turbo door EFA-STT®.

The transparent turbo door.

Thanks to laths made of crystal-clear acrylic glass, the door leaf of the EFA-STT® is over 70 percent transparent – this makes it a unique high-speed door worldwide: robust and yet almost completely transparent. The ability to see clearly through the door offers critical advantages at all passageways in your company which are passed through from two directions: Accidents are prevented and smooth transport operations are guaranteed.

In order to maintain transparency even after years, the door leaf of the EFA-STT® is kept at a distance in the spiral. The transparent laths are thus wound up without touching one another and remain almost wear-free. As a result, the entire door always impresses with its glossy and scratch-free appearance, even in everyday working life.

  • The door leaf consists at 70% of crystal clear acrylic glass
  • Opening up to 3.0 m/s
  • Closing up to 1,0 m/s
  • Highest wind load capacity
  • Top safety devices
  • Up to 200,000 operating cycles p.a.
  • Standard sizes of up to w=8,000 mm, h=7,800 mm


Wear-free door leaf guide Open

The EFAFLEX spiral does not wind the door blade onto a shaft, but keeps it at a distance to save space. This design optimally combines highest opening speeds, durability and effectiveness. Thanks to the spiral, the doors run quietly with no wear and look like new for years to come.

Natural incidence of light Open

The transparent laths of the EFA-STT® provide sufficient light and brightness. This particularly makes work easier in air locks, such as those used in the automotive industry. In addition, transparent laths ensure an unobstructed view with open lines of sight between the rooms.

Universal use Open

Due to its product features, such as the modern, transparent appearance, the fast opening speed and sizes of up to 8,000 x 7,800 millimetres, the EFA-STT® is suitable for a wide range of applications. In addition, you can customise the laths and thus adapt the door to the desired application. All transparent sections of the EFA-STT® are made of PVC-free acrylic glass as standard. Upon request, any desired combinations of grey and transparent laths can also be supplied.

High-end safety technology Open

As the world’s leading manufacturer of high-speed doors, it is our aspiration to also be pioneers in the field of safety: All EFAFLEX products meet the highest standards and protect both people and the goods as well as the door itself.
It is not only our industrial doors that impress with their state-of-the-art safety technology, but also the associated systems: EFA-SCAN®, for example, is the world’s first laser scanner for use on doors, which is a reliable pulse generator and safety system in one.
