Sundström SR 99-1 Compressed Air Filter – Clean Breathing Air for Professional Respiratory Protection Systems
The Sundström SR 99-1 compressed air filter was designed to convert ordinary compressed air into clean, breathable air. Particularly in paint booths, industrial coating work, or workshops with high pollutant levels, the system ensures reliable air purification and protects users from oil, particles, vapors, and odors.
Why a Compressed Air Filter for Breathing Air is Indispensable
Normal compressed air from compressors often contains oil particles, moisture, dirt, as well as odors or vapors. This air quality is not sufficient for respiratory protection systems. The SR 99-1 filters coarse and fine particles as well as gaseous impurities, delivering significantly cleaner breathing air for professional applications.
The filter system operates with a pre-separator, particle filters, and an activated carbon section. This reduces even very small impurities. Additionally, the device features an automatic drainage system to reliably discharge accumulated liquids.
Product Overview
| Property | Details |

The compressor's intake air should be positioned as far away as possible from paint mist, exhaust fumes, or solvent vapors. This significantly extends the service life of the filter system.
Recommended Basic Settings
The following values serve as practical guidelines and should be checked depending on the compressed air system and connected devices:
- Supply pressure: approx. 6–10 bar
- Recommended airflow: up to 900 l/min
- Minimum 11 mm internal diameter of the supply line
- Regular inspection of the drainage system
- Change the filter element at the latest if odors occur or if there is a significant weight increase
Professional Workflow for Daily Use
- Position the compressor at a clean air source.
- Check compressed air lines for leaks and contamination.
- Connect the SR 99-1 correctly and check the operating pressure.
- Check the automatic drainage.
- Connect the respiratory protection system or pneumatic device.
- Monitor for odors or pressure drops during operation.
- Check the filter and drainage after finishing work.
Practical Troubleshooting
1. Air smells of oil or solvent
- Check and replace filter element if necessary
- Check compressor intake
- Check compressed air quality
2. Pressure loss in the system
- Check lines and couplings
- Avoid insufficient line diameters
- Check filter for contamination
3. Moisture in the compressed air
- Clean the drainage system
- Check compressor maintenance
- Check pre-separator
4. Unusual air noises
- Check couplings
- Close filter housing correctly
- Check hoses for damage
Maintenance and Care
- Regularly clean the exterior with mild soapy water
- Regularly check the drainage container
- Keep the pre-separator clean
- Replace seals if damaged
- Regularly weigh and document the filter element
