Sundström SR 200 Airline with Glass Visor: Compressed Air Respiratory Protection for Heavy-Duty Use
The Sundström SR 200 Airline with a glass visor is a compressed air-supplied full-face mask designed for demanding tasks where high breathing comfort, reliable protection, and a clean air supply are critical. It is particularly suitable for long or physically taxing activities, as well as situations where pollutants are difficult to detect or especially hazardous.
What is the SR 200 Airline?
The SR 200 Airline is a respiratory protective device with a continuous airflow for connection to a suitable compressed air supply. Positive pressure is created inside the mask, reducing the ingress of contaminated ambient air. The version with a glass visor is intended for robust applications where clear vision and a durable design are essential.
Product Overview: Use, Advantages, and Variants
| Feature | Practical Benefit | Note |
|---|---|---|
| Compressed Air Operation | Continuous airflow for long-duration work | Check breathing air quality and system capacity before use |
| Backup Filter Option | Can provide support when moving between work areas or during air interruption | Only with suitable filter and correct seal check |
| Glass Visor | Robust visor for demanding applications | Glass visor is listed as a variant/accessory in product documentation |
| Warning Whistle | Warns if the air supply falls below the recommended range | Safely leave the contaminated area if warning sounds |
Recommended Basic Settings as Guidelines
The following values are practical guidelines and do not replace a risk assessment, operating instructions, or national regulations.
- Airflow: minimum 150 l/min; for higher exertion, adjust as needed up to approx. 320 l/min.
- Working Pressure: 5–7 bar at the connection to the control valve.
- Breathing Air: must meet breathing air requirements; if in doubt, use a suitable compressed air filter.
- Hoses: use only approved Sundström compressed air hoses individually; do not combine them.
- Temperature: operation within the specified range of approx. -10 to +55 °C.
Professional Workflow: Start Safely in 7 Steps
- Visually inspect the mask, membranes, sealing surfaces, head harness, and filter connection.
- Check the nominal capacity of the compressed air system and the number of connected users.
- Connect the breathing hose to the control valve and correctly attach the compressed air hose.
- Check the airflow with a flow meter; the marker must at least be reached.
- Put on the mask, tighten the head harness straps in pairs, and ensure a comfortable, tight fit.
- If using a backup filter, perform a seal check and rule out leakages.
- Adjust the airflow at the control valve according to the workload and watch for warning signals during work.
Troubleshooting: Typical Problems and Measures
1. Airflow too low
- Hold the flow meter vertically and check that the ball moves freely.
- Check hoses for kinks, twists, or blockages.
- Verify the capacity of the compressed air supply and the number of connected users.
2. Mask won't seal
- Readjust the head harness and repeat the seal check.
- Check the inhalation and exhalation membranes and valve seats.
- Avoid eyeglass temples, stubble, or hair in the sealing area.
3. Warning whistle sounds
- Stop work and safely leave the contaminated area.
- Check the air supply, control valve, hose routing, and system pressure.
- Only reuse equipment after a successful functional test.
4. Vision or comfort decreases
- Clean the visor and check for damage.
- Clean the mask with a mild soap solution; never use solvents.
- Use original spare parts in case of wear and tear.
Maintenance: 5 Points That Matter in Practice
- Perform a visual inspection before and after use.
- Conduct a functional test before use, especially regarding airflow and tightness.
- Clean after use; for heavy soiling, use a mild soap solution up to 40 °C.
- Keep exhalation membranes and valve seats particularly clean.
- Replace membranes, head harness, and damaged parts promptly with original parts.

View product nowFAQ about the Sundström SR 200 Airline
What is the SR 200 Airline particularly suitable for?
For heavy or long-duration work where filter devices would be recommended, but more breathing comfort via compressed air supply is desired.
Can the mask be used with a backup filter?
Yes, the SR 200 Airline is designed for filter backup. This is particularly relevant when changing work areas or in case of an unintended interruption of the air supply.
What airflow is required?
The minimum airflow is 150 l/min. Depending on the workload, the airflow can be adjusted up to approx. 320 l/min.
What to do if the warning whistle sounds?
The signal indicates insufficient air supply. The contaminated area should be safely vacated and the system inspected.
Can I wear normal glasses under the mask?
Normal eyeglass temples can cause leaks. It is better to use a compatible spectacle frame designed for the mask.
Conclusion
The Sundström SR 200 Airline with a glass visor is a powerful solution for professional compressed air respiratory applications. Consistent checking of airflow, seal, breathing air quality, and maintenance provides a comfortable system for demanding work with a clear focus on practical use.
