SR 500 Respirator unit with standard battery.

The low weight and ergonomic design of the respirator and belt provide a high level of comfort.

Easy single-button control. Two airflows, +175 and +240 l/min, to ensure a high level of protection. These values are kept constant throughout the operating time by the unit’s automatic flow regulator.

Long operating time, up to 13 hours, in combination with fast-charging lithium-ion batteries make for disruption free use without unnecessary interruptions.

Automatic flow regulation compensates for clogged filters. Self-calibrating based on choice of mask and filter.

Unique alarm system with vibrating, audio and visual alarms when airflow is obstructed, the filter clogged or battery level low.

Ball-bearing fan motor with balance fan wheel ensures long and reliable operating time.

EMC approved electronics which emit minimal electro-magnetic radiation and unaffected by electro-magnetic fields.

Removable intelligent lithium-ion battery for rapid charging without the need to discharge.

The SR 520 face shield, SR 500 battery-powered fan and approved filters are included in the Sundström fan-assisted respiratory protection system.

The breathing hose from the face shield is connected to the filter-equipped fan.

The overpressure formed in the screen prevents particles and other contaminants from entering the shield.

The equipment can be used as an alternative to filter protection in any situation where it is recommended. This is particularly true in the case of heavy, hot or protracted working situations.
