Turbo speed for full transparency
When speed is the first priority, you will find no better solution than the transparent clean room door EFA-STT®-CR. Thanks to the patented spiral, this high-speed door opens and closes reliably with up to 2.5 m/s. It is particularly suitable if the exchange of pressure and atmosphere are to be minimised, e.g. during the inertisation for try fire prevention. Compared with a normal EFA-STT®, its tightness in use for clean rooms is achieved by means of so-called labyrinth packings.
The fixed door leaf which is made of single-walled transparent laths is kept in a certain distance during winding up. Thus, the EFA-STT® of the CR series remains transparent for many years - also for door sizes of 4x5 metres!
