High-speed folding door of the type “EFA-SFT®” with electro-pneumatic drive, connection to compressed air with 4-6 bars and power 230 Volts, winged segments coupled and centrally divided. Wings can be opened up to 90 degrees each;
The door system mainly consists of:
Door leaf elements of special anodised aluminium profiles in module type, which are separated from the steel frame and which are bolted and therefore easy to exchange. Door leaves horizontally divided up into … fields, large window (up to 85% of the door surface) made of acrylic glass, about 4 mm thick, fully transparent. Steel parts galvanised as standard, aluminium parts E6/EV1 anodised, door leaves are sealed towards one another as well as towards the vertical steel frames and the opener box, floor seal with sealing brush, rubber profile sealings between the wing segments, main closing edge sealed with hollow chamber rubber, at the same time developed as finger pinch guard, no guide rails on the floor.
Universal joint technology for the even weight distribution over the whole working area.
