Self-repairing door - AR 300

High-speed door designed to close indoor areas with a modest workflow. Self-repairing (or self-retracting) function. 

Evolution of the AR 600 high-speed door model, the AR 300 technical closure is suitable for small internal openings where a normal workflow is expected but without giving up the self-repair function of the closure. The high-speed door can therefore immediately resume operation thanks to the automatic restoring of the curtain. This model is excellent value for money.
