Sundström SR 500 / SR 520 M/L PAPR complete respiratory protection system with fan unit, protective hood and P3 filters

The Sundström SR 500 / SR 520 M/L complete system is a high-performance powered air-purifying respirator solution for demanding working environments. The combination of a blower unit and a lightweight hood offers reliable protection whilst ensuring high wearing comfort – ideal for long and physically demanding operations.

The system operates with a battery-powered blower that directs filtered air into the hood via a breathing tube. The resulting positive pressure effectively prevents the ingress of harmful substances and ensures a consistently safe breathing zone.
