Sundström 307 compressed air package is an airline-based respiratory protection system for demanding industrial use. It is designed for environments with high contaminant levels where continuous breathable air supply and full-face protection are required.

General information

The Sundström 307 system is designed for situations where filtering respirators are insufficient or usage duration is extended. The key functional benefit is the elimination of breathing resistance through compressed air, supporting more consistent work performance in demanding conditions.

The solution is particularly suitable for applications with continuous exposure where respiratory protection must operate reliably throughout the entire work period without performance degradation.

Benefits and differences compared to similar products

• Compressed air system eliminates breathing resistance compared to filtering respirators in long-duration use.
• SR 307 unit provides continuous airflow and includes a pressure drop warning function.
• SR 99 filter ensures breathable air quality independently from the compressed air source.
• Modular design allows the same full face mask to be used with different protection systems.

Intended use

The product is suitable for industrial users, supervisors and HSE evaluation in applications such as painting, heavy industrial work and other high-exposure tasks. It is intended for use where continuous air supply and full-face protection are required.

The product is not suitable without a compliant compressed air source or in environments where air quality cannot be verified. In practice, the system is selected when filter-based protection is insufficient due to exposure level or duration.

Asbestos removal 2025: regulatory robustness of respiratory protection

Regulation concerning asbestos removal is tightening, increasing the employer’s responsibility for ensuring adequate respiratory protection. Inspections focus on whether protection can be considered unequivocally sufficient in all conditions, not only permitted.

As a result, operators are transitioning to compressed air-based respiratory protection as a solution that does not require post-assessment interpretation. Compressed air systems provide clear compliance, consistent protection levels in demanding environments and improved user confidence.

• Clear regulatory robustness without ambiguity
• High and consistent protection level in demanding conditions
• User confidence in the protection solution

Implementation requires assessment of current respiratory protection and, if necessary, transition to compressed air systems before regulatory changes take effect to avoid urgent corrective actions.
