Abstract: A paint gun for atomizing (in particular by way of compressed-air-assisted atomization) and applying a coating material such as a paint has a material-guiding part, a non-material-guiding part, and a transmitting and/or receiving device for wireless signal transmission. In order to increase the functional reliability and provide optimal operability in the environment in which the coating material is applied, the transmitting and/or receiving device for wireless signal transmission is arranged at a distance from the material-guiding part and is associated with the non-material-guiding part. Alternatively or additionally, an increased functional reliability is achieved by designing the transmitting and/or receiving device for wireless signal transmission in accordance with two different radio standards. Furthermore, a material application system comprising such a paint gun as well as a method for operating same are described.

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.

Abstract: A portable breathing apparatus for protecting a user against contact with the contaminated surrounding atmosphere. The breathing apparatus can be supplied with fresh breathable air via an air tube connected to an air supply system having an overpressure. The breathable air flows out of a body which is connected to the air tube and has at least one defined outflow surface for the breathable air.
