Abstract: A skull mounting system for headgear, preferably a respirator hood, includes a headband with a front headband and a rear headband. The front headband extends around at least the front of the head of the wearer and the rear headband is found on the back of the head of the wearer, and at least one upper headband is provided that extends over the top of the head of the wearer. The upper headband has higher elasticity than the front and rear headbands.

Abstract: A skull mounting system for headgear, preferably for a respirator hood, is described. The skull mounting system comprises a headband with a front head strap, which extends around the front of the head of a wearer, and a rear head strap, which is found on the back of the head of the wearer. The rear head strap is connected to the front head strap by means of two swivel joints. The swivel joints are at least partially freely rotatable in a corresponding adjustment position and are not rotatable in a corresponding locked position.

Abstract: A temperature-control device for heating and/or cooling gases or gas mixtures. The temperature-control device includes at least one air inlet, at least one air outlet and at least one vortex tube. The vortex tube(s) each have a vortex tube inlet, a hot air outlet and a cold air outlet. The at least one air inlet is connectable with at least one vortex tube inlet of the at least one vortex tube. The at least one air outlet can be connected at least in one flow direction with at least one hot air outlet and at least one cold air outlet of the vortex tube(s). At least one control element selectively adjusts the amount of air flow between the at least one hot air outlet and the at least one air outlet or between the at least one cold air outlet and the at least one air outlet.

Abstract: A temperature control device for heating and/or cooling gases or gas mixtures, in particular for use in the respiratory protection sector. The temperature control device has a housing, a compressed air input, a supply output and a vortex tube with an air inlet, a hot air outlet and a cold air outlet. The vortex tube is installable in at least two final assembly arrangements. In a first arrangement, there is a fluid-conducting connection between the cold air outlet of the vortex tube and the supply output of the temperature control device and, in a second arrangement, there is a fluid-conducting connection between the hot air outlet of the vortex tube and the supply output of the temperature control device. By this configuration, the temperature control device is both a device for heating and cooling respiratory air from mainly the same components with little additional outlay on production and little additional effort during assembly.

Abstract: An activated carbon adsorber, in particular an activated carbon adsorber for use by a user of an externally ventilated breathing mask or breathing hood. The activated carbon adsorber includes a housing for accommodating a filter cartridge, and the housing has the following features: an air inlet supply port to receive compressed air from an air supply unit; a connector for connecting to a breathing mask or hood; a unit which can be fastened to the body of or to or on the housing of the activated carbon adsorber and which is capable of forming a detachable connection with another component in particular a sliding or slip connection.
