Compressed air set Sundström SR 307

Sundström SR 307 compressed air attachment is a respiratory protection accessory used to connect a half mask or full face mask to a compressed air supply for continuous airflow operation in industrial, maintenance, and process environments. It is intended for applications with high contaminant levels, poor warning properties, or extended work duration.

General Information

The Sundström SR 307 is a compressed air attachment that converts a compatible facepiece into a continuous flow respiratory protective device. Its primary functional benefit is a stable airflow that reduces breathing resistance compared to filter-based use in demanding work conditions.

From a procurement perspective, it is essential to ensure availability and quality of compressed air as well as compatibility with the selected facepiece.

Technical Specifications

• PRODUCT TYPE: Compressed air attachment for respirators

Key Benefits and Differences Compared to Alternatives

• Converts a filter-based facepiece into a compressed air system without requiring a separate full system replacement.
• Belt-mounted control valve enables airflow adjustment during use.
• Suitable for explosive or flammable environments due to non-sparking construction.
• Allows combined use of compressed air and filter-based backup within the same system configuration.

Applications

The product is suitable for users, supervisors, HSE professionals, and procurement in applications requiring continuous airflow respiratory protection such as painting, process work, and maintenance. It is particularly applicable where contaminants are toxic or difficult to detect.

The product is not suitable for use without a compressed air system or where breathing air quality cannot be verified. Selection is based on contaminant type, duration of use, and available infrastructure.
