vevkészülék

A vevkészülék, commonly translated as a breathing apparatus or respirator, is a device designed to supply breathable air to an individual in environments where the air quality is compromised or insufficient. These devices are crucial for safety in various hazardous conditions, including firefighting, diving, mining, and industrial work where toxic fumes or oxygen deprivation may be present.

There are several types of vevkészülék, broadly categorized into supplied-air respirators and self-contained breathing apparatus (SCBA). Supplied-air respirators draw air from a clean external source, often through a hose, while SCBA units carry their own supply of breathable air in a tank. The choice of vevkészülék depends on the specific application, duration of use, and the nature of the hazard.

Key components typically include a facepiece or mask that seals to the user's face, a regulator to control airflow and pressure, and for SCBA, a compressed air cylinder. Filters can also be incorporated to remove specific contaminants from the air. Proper fit, regular maintenance, and thorough training are essential for the effective and safe operation of any vevkészülék. Their primary purpose is to protect the wearer's respiratory system and ensure they can breathe safely in dangerous atmospheres.
