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.

Application: for internal use only

Opening speed: 0,7 m/sec

Standard metal structure:
top cross member in die-bent sheet metal made of galvanized steel thickness 1.5 mm, non-self-supporting, equipped with fixing plates to be bolted. Galvanized steel lateral jambs, fitted with slotted fixing brackets for adjustment.

Curtain: Tear-resistant, PVC, 900 g/m². At eye level, one row of transparent heat-sealed inspection windows. Electrowelded side sealing hinges.
