Supplied-air respirators

Supplied-air respirators (SARs) are specialized protective devices that deliver clean, breathable air from a separate source, such as a compressor or stored cylinder, directly to the user through a hose. They are used in environments with hazardous airborne contaminants, such as chemicals, dust, or toxic fumes, where standard masks are insufficient. Unlike filter masks, SARs provide a continuous supply of purified air, enabling users to work safely in dangerous atmospheres for extended periods. They are commonly employed by professionals in industrial settings, firefighting, and rescue operations to ensure respiratory protection.
