Blobel - Model Type BL/BDD-PM -Retention Barrier
Suitable for crack-free surfaces with up to 20 mm (± 10 mm) of floor/ground unevenness, e.g. concrete, corrugated sheet metal, tiles, stones, etc. The Retention Barrier is comprised of two trapezoidal, integral hollow aluminium profiled sections (elements). A compressible, highly adaptable special seal is affixed on its lower sides and end faces.
Both swivelling devices are securely mounted and sealed to the floor/ground and wall next to the opening to be protected. The closure bodies, firmly bolted in the hinges, are reinforced in the centre and provided with a mounting eye for pneumatic cylinders. A thrust-type tension device is also mounted on one of the closure bodies. Pneumatic cylinders are linked to the special mounts. Operating pressure 4-10 bar.
Barrier bodies and mounting fixtures are furnished with a red paint finish, preferably “traffic red” RAL 3020. The remaining metal components are galvanized or made of aluminium.
