SR 500 EX

The SR 500 EX fan unit is engineered for safe operation in explosive and hazardous environments, delivering dependable performance where protection is critical. Designed as part of Sundström’s powered respiratory systems, it works seamlessly with compatible filters and head-tops to provide continuous, filtered airflow.

Ideal for intensive, high-temperature, or long-duration tasks, this fan unit reduces breathing resistance and enhances user comfort compared to traditional filter-based solutions. It draws in contaminated air, passes it through high-efficiency filters, and delivers clean air via a breathing hose to the head-top.

By maintaining positive pressure inside the head-top, the system effectively prevents harmful particles and gases from entering, ensuring a safer and more comfortable working environment for professionals in demanding conditions.
