Series S - STT by EFAFLEX

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. 

The door leaf consists at 70% of crystal clear acrylic glass
