摘要： A method and system for controlling ventilation in a welding helmet is provided. The invention may be adapted to a wide variety of system types, and may reduce or eliminate the need for a shroud or barrier around the head and neck of the welder, of the type used in PAPR systems. The airflow system includes forward and rearward air streams, directed onto the face of the welder, onto the top of the head of the welder, and toward the back of the head of the welder. The air streams help to cool the welder, provide a fresh source of air for breathing, and create a positive pressure system that reduces or excludes entrainment of contaminated external air into the forwardly directed air flow. Certain embodiments may include streams that are filtered, split or redirected via deflectors and conduits to achieve the aforementioned goals.

摘要： An airflow system is provided for a welding helmet. The airflow system includes an air intake with a filter, a blower, and a battery mounted to the rear of headgear for a welding helmet. A manifold wraps around the side and front of the headgear and directs air from the blower to the front of the headgear. The manifold includes a lower vent for directing air onto a user's face and an upper vent for directing air over a user's head toward the rear of the headgear. The vents are intended to create positive pressure to impede the entry of unfiltered air into the user's breathing zone. The manifold further includes a portion of flexible tubing for adjusting the size of the airflow system in conjunction with adjustment of the headgear diameter. The airflow system generally conforms to the structure and shape of the headgear to maintain a location close to the user's head.

摘要： Various embodiments comprise apparatuses and methods for capturing particles from a particle-laden airstream. An embodiment of a device includes an inlet air passage to direct a particle-laden airstream, an outlet air passage, an impaction nozzle in fluid communication with and downstream of the inlet air passage, and a channel in fluid communication with and downstream of the impaction nozzle and upstream of the outlet air passage. An open portion of the channel is oriented substantially toward the inlet air passage and has a cavity at least partially covered with a substrate material. A base of the substrate material is substantially normal to an incoming direction of the particle-laden airstream. Other embodiments of the device and a method of using the device are also provided.
