How to Use the Sundström SR 570 with SR 507 Correctly
The Sundström SR 570 with SR 507 compressed air respiratory protection system combines high wearing comfort with a reliable breathing air supply for demanding industrial and coating work. In this practical guide, you will learn how to connect the system correctly, check the airflow rate, and avoid common mistakes.
Product Overview
| Feature | Description |
|---|---|
| System Type | Compressed air respiratory protection with continuous airflow |
| Compatible Headtops | SR 570, SR 580, SR 540, SR 520, SR 530, and other Sundström headtops |
| Airflow | Approx. 175–260 l/min depending on valve setting |
| Applications | Painting, coating, grinding work, industry, chemicals |
| Standard | EN 14594 Class 3A/3B |
Always check the airflow using the supplied flow meter. The ball should at least reach the upper mark. Insufficient airflow can significantly reduce protection.
Recommended Basic Settings
The following values serve as practical guidelines and should be checked depending on work intensity, hose length, and compressed air supply.
| Setting | Guideline Value |
|---|---|
| Baseline Airflow | At least 175 l/min |
| High Work Intensity | Use increased airflow up to approx. 260 l/min |
| Compressed Air Quality | Use breathing air low in oil and pollutants |
| Recommended Additional Filtration | SR 99-1 compressed air filter if air quality is uncertain |
Pro Workflow for Safe Use
- Check the compressed air supply and the number of connected users before starting work.
- Connect the adapter to the breathing hose of the headtop, then connect the control valve.
- Check the airflow with the flow meter. The ball must at least reach the upper mark.
- Put on the belt and position the valve on the side of your body so it remains accessible at all times.
- Put on the headtop and carefully adjust the headband and fit.
- Regulate the airflow to match your physical exertion during work.
- Leave contaminated areas completely before removing the system or disconnecting the couplings.
Common Problems & Solutions
| Problem | Actions |
|---|---|
| Airflow too low | Hold the flow meter vertically, check hose connections, open the valve further |
| Unpleasant odor in breathing air | Check compressed air quality, use a compressed air filter, check the compressor |
| Moisture in the system | Check dew point, check air treatment, dry hoses |
| Uncomfortable fit | Readjust headband, optimize hose routing, adjust belt position |
Maintenance & Care
- Perform a visual inspection before each use
- Repeat functional tests regularly
- Clean with a mild detergent or Sundström cleaning wipes
- Do not use aggressive solvents
- Allow components to dry completely after cleaning
