Unified protective section UZS-25

The unified protective section UZS-25 consists of a support frame (1), a door frame (2) (welded from profile steel), and three UZS-1 sections mounted on the door frame. The support and door frames are connected by hinge and locking mechanisms. These mechanisms allow adjustment of the door frame’s tightness against the support frame, with a rubber gasket placed between them.

To ensure airtight sealing between the base and the support frame, rubber gaskets are installed. For mounting the UZS-25, the support frame has eight holes for anchor bolts with a diameter of 16 mm.

The blast-proof protective section UZS 815x2200 is installed in air intake and exhaust ducts when passage through them is required. The door frame of the UZS 815x2200 opens to the right when viewed from inside the shelter. If left-hand opening is required, the blast-proof protective sections should be rotated 180 degrees: remove the sections and reinstall them with the blades facing downward.
