Abstract: A respirator includes a head unit configured to be received on a human head and a purifying unit configured to provide purified air to the head unit. The purifying unit includes a first housing portion having an interior side defining a blower cavity, an exterior side defining a partial filter chamber with a filter sealing surface, and an inlet hole circumscribed by the sealing surface and extending between the interior and exterior sides. A second housing portion has an interior side defining a blower cavity. The first and second housings are attached to each other to form a housing such that the blower cavities are opposite each other to define a blower chamber within the housing. A blower is disposed in the blower chamber. A filter covers over the inlet hole and is disposed against the sealing surface such that air entering the hole passes through the filter.

Abstract: A cold ambient battery chilling mode of an electric vehicle may be implemented if the vehicle battery is being charged when the ambient air temperature is low and a temperature of the battery is elevated. During cold ambient charging, coolant flows through a heater core and through a battery heat exchanger. Cold ambient air may be utilized to cool the coolant flowing through the heater core, and coolant from the heater core flows through the battery heat exchanger and cools the battery during charging. A battery chiller may be deactivated when the cold ambient battery chilling mode is activated to reduce energy consumption.

Abstract: A powered air-purifying respirator (PAPR) assembly includes, among other things, a tube extending from a filtration unit to a headpiece system. The tube is biased toward a looped position where the tube includes a loop. A PAPR manufacturing method includes, among other things, reorienting a tube to have a loop by placing the tube about a mandrel, heat-treating the tube, and removing the mandrel from the tube. The tube is biased toward a looped position after the removing due to the heat-treating while the tube is reoriented to have the loop.

Abstract: An air duct system for passing an air flow emanating from an air outlet to a measurement device for detecting parameter measurement values for at least one parameter of the air flow, includes at least one collecting unit for collecting the air flow emanating from the air outlet. That one collecting unit can be disposed on the air outlet so that a contact surface of the collecting unit encloses at least one outlet opening of the air outlet circumferentially. The collecting unit includes a wall defining a continuous air duct with an inlet end section and an outlet end section.
