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.

A hose that includes a main body portion that defines a lumen extending therethrough and includes an outer surface, at least a first axially extending protrusion extending outwardly from the main body portion, and at least a first axially extending slot defined in the outer surface of the main body portion. The hose defines a hose axis. A portion of the first axially extending protrusion is secured in a portion of the first axially extending slot.

A Personal Protective Equipment (PPE) ensemble made up of a launderable protective hood and an air dispersion protective headgear, is provided. In an exemplary embodiment, the PPE ensemble is made up of a launderable hood that is detachably affixed to and forms a gas-restrictive seal with a protective face shield assembly, an air-supplied protective suit having an air supply inlet/outlet assembly, and an air dispersion protective headgear releasably coupled to the air supply inlet/outlet assembly of the protective suit. The PPE ensemble provides a wearer with a protective hood with reduced or no lens fogging and reduced sound levels under the hood. The PPE ensemble also maintains or cools the skin temperature of the wearer's face during use and thus reduces wearer fatigue.
