The Sundström SR 500 is a belt-mounted Powered Air Purifying Respirator (PAPR) that supplies a continuous flow of filtered air to the user's breathing zone, creating positive pressure inside the head-top or facepiece. This positive pressure significantly reduces breathing resistance while helping prevent airborne contaminants from entering the respiratory system, making it an ideal solution for prolonged use in challenging work conditions.

Powered by a high-performance lithium-ion battery, the SR 500 offers up to 13 hours of operating time, depending on battery selection and filter configuration. The intelligent airflow control automatically compensates for filter loading, air pressure, and temperature changes to maintain consistent airflow throughout operation. The unit also features an easy-to-read display with visual and audible alarms that notify users of low battery, reduced airflow, or blocked filters, ensuring maximum operational safety.

One of the key strengths of the SR 500 is its modular compatibility. A single blower unit can be used with multiple Sundström headtops—including hoods, face shields, safety helmets, welding shields, half masks, and full face masks—allowing organisations to adapt quickly to different applications while reducing equipment costs. The system supports particulate filters, gas filters, or combined filters, making it suitable for a wide range of industrial hazards.

Manufactured in Sweden with exceptional engineering standards, the SR 500 delivers outstanding durability, reliability, and user comfort. It is trusted in industries such as pharmaceuticals, chemical manufacturing, healthcare, laboratories, painting, metal fabrication, emergency response, and hazardous material handling.
