EFA-SRT-EX - Explosion-Proof Roll-Up Doors

In addition to a standard frequency converter and a microprocessor control system, the EFA-SRT EX for internal use comprises all the typical basic features of modern door technology, such as dynamic door tension and emergency opening via spring systems in the frame members. A hand lever on the frame member allows quick emergency opening of the door system in the event of a power failure. The door leaf is formed by a black, non-transparent special ATEX curtain.
