Securing you: the EFAPROTECT Series


Based on nearly 50 years of industry expertise and market knowledge, we have further developed the EFAPROTECT Series, which has been designed to provide extra protection to safeguard people, and assets. EFAFLEX already has 5 high-speed doors in this range, which are certified according to DIN EN 1627 et seq, resistance class 2 (WK2). We are constantly innovating our products in order to meet the changing requirements of the market and above all the needs of our customers. The introduction of a high-speed door of resistance class 4 (WK4) was the logical next step. The new EFA-SST®-Secure can withstand an attack by even experienced perpetrators when using heavy duty impact tools such as electric drills.


Protection against attacks and burglaries


Why are security doors necessary? All buildings that have external exposure or exits such as windows or doors, have a weak or more vulnerable point where access can be gained at the moment of inadequate security or protection. In the worst case, this can happen faster than expected, as attackers are becoming more professionally equipped and well prepared. This our latest high-speed door solution will help protect human life and property against theft, vandalism or robbery. The door is designed for extreme demands. An automatic locking mechanism on both sides ensures that once the door is in the closed position, it cannot be lifted from outside, even with when put under considerable force, which makes it suitable for inclusion in complete security concepts: 

"The requirements for security concepts are becoming increasingly stringent which is why we are particularly proud that our new high-speed door meets the criteria: A unique offer that is only available from EFAFLEX", says Project Manager Klaus Manlig.

Works in record speed


We know wherever security is important, speed of action makes a difference. That is why our new security door opens and closes in the shortest possible time: The EFA-SST®-Secure opens with a maximum speed of 1.0 m/s and closes with a speed of 0.6 m/s and durable enough to operate up to 250,000 load cycles per year.
