A high-pressure connector (10), for a fluid-communicating connection of a breathing gas source (200) of a respirator to a pressure reducer (110), includes a connector upper part (20) with a connector upper part duct (22) with an inlet opening (24) for the inflow of breathing gas from the breathing gas source (200). A connector lower part (30) has a connector lower part duct (32) with an outlet opening (34) for the outflow of breathing gas into the pressure reducer (110). The connector upper part (20) is fastened reversibly with a fastening interface (26) to a counter-fastening interface (36) of the connector lower part (30). The connector upper part duct (22) is in fluid-communicating connection with the connector lower part duct (32). A filter device (40) is arranged in the connector upper part duct (22) in at least some sections for filtering solid particles out of the breathing gas.

A user-wearable breathing apparatus is disclosed. Air may be passed through an air irradiating chamber coupled to an ultraviolet light source and configured to irradiate the air irradiating chamber with ultraviolet light. An ultraviolet-opaque cover substantially surrounding the user-wearable breathing apparatus may be provided. A hose may be passed through an opening in the ultraviolet-opaque cover to direct processed air to the user. The hose may be configured to attach to an optional head-wearable breathing assembly. In some embodiments, the air may be passed through the apparatus in response to the user’s breathing, while in other embodiments, fans are used. In other embodiments, the oxygen content of the processed air may be increased by techniques such as nitrogen scrubbing and injecting oxygen into the air while it is being processed.

A breathing tube (1), for a respirator (2), includes a flexible tube body (3) with a tube axis (4), with a first tube end (5) and with a second tube end (6). A molding (7) is formed at the first tube end (5). The molding (7) extends at least partially along the tube axis (4) away from the first tube end (5) of the tube body (3). A respirator (2) may be provided, including the breathing tube (1), a breathing unit (14) and a breathing air supply device (15). A breathing tube port (16) is formed at each of the breathing unit (14) and at the breathing air supply device (15) for connecting the breathing tube (1). A mounting device (17) is formed at at least one breathing tube port (16) for mounting the molding (7) of the breathing tube (1).
