The following pneumatic and physical parameters from the manufacturer serve as guide values for system performance in factory-new condition:
- Inhalation Resistance (with particulate filter): Approx. 44 Pa at a continuous volume flow of 30 l/min (guide value for breathing comfort).
- Exhalation Resistance: Approx. 56 Pa at a volume flow of 160 l/min (ensures effortless escape of exhaled air).
- Permissible Operating Temperature: -10 °C to +55 °C (at relative humidity below 90 % RH). When using the explosion-proof fan unit SR 500 EX, a guide value of -10 °C to +40 °C applies.
- Storage Conditions: -20 °C to +40 °C in a clean, dry environment (< 90 % RH) away from direct sunlight.
The Professional Workflow: Donning the Mask Correctly
Respiratory protection only provides 100% safety if the mask seals perfectly against the face. Proceed systematically according to this guide before starting every shift:
- Check and Insert Filter: Choose the appropriate filter medium (e.g., particulate filter SR 510 P3 R or gas filter). Verify the expiration date. Press the filter into the mask connection so that the orientation arrows on the filter point directly toward the face. The filter edge must sit flush all around inside the inner groove of the mounting fixture.
- Prepare Harness Straps: Loosen the four elastic straps of the head harness completely by pushing the strap holders forward. Open the buckles of the upper two non-elastic straps.
- Position the Mask: Pull the head harness far upward. Place your chin firmly and centered inside the designated chin support of the mask body, then pull the straps backward over your head.
- Secure Harness Straps: Tighten the elastic straps evenly in pairs toward the back. The mask should rest flush everywhere without painful pressure points. Next, adjust the upper non-elastic straps and close the buckles.
- Fit Check (Negative Pressure Test): Attach the pre-filter holder along with pre-filter SR 221 onto the filter. Place your palm flat and gently over the opening of the pre-filter holder to completely block the airflow. Inhale deeply and hold your breath for about 10 seconds.
- Verify Face Seal: If the mask body draws noticeably against your face and the negative pressure remains stable, the mask is perfectly sealed. If air escapes or you feel a draft, readjust the straps or check the valves. Repeat the test until absolute tightness is achieved.
Troubleshooting
Should faults or leaks occur during practical daily operations, systematically check the following error sources and countermeasures:
• Measure B: Inspect the inhalation and exhalation membranes for contamination or distortion and clean the valve seats.
• Measure C: Increase tension evenly on the pairs of straps without distorting the mask body.
• Measure B: Check the upstream pre-filter SR 221. If it is visibly clogged or damp, replace it to extend the main filter's lifecycle.
• Measure B: Check the function of the three inhalation membranes inside the inner mask. If blocked, the airflow will not route correctly past the visor.
• Measure B: Verify the expiration date of the filter as well as the integrity of its housing. Dispose of damaged filters immediately.
Maintenance & Cleaning
Regular care ensures protective performance and keeps the mask ready for action over years. Adhere strictly to the following sequence:
- Daily Cleaning: Use Sundström cleaning tissues SR 5226 for quick intermediate cleaning after shift completion.
- Intensive Cleaning: For heavy contamination, dismantle all filters, adapters, the two exhalation valve caps with their membranes, as well as the three inhalation membranes and the head harness.
- Washing Process: Clean the mask body with a mild, warm soap solution (maximum +40 °C) and a soft brush. Rinse everything thoroughly with clean water. Important: Never use solvents!
- Disinfection & Drying: If necessary, the mask can be disinfected using a 70% ethanol or isopropanol solution. Allow all components to air-dry completely at room temperature before reassembling.
- Wear-and-Tear Part Replacement: Replace damaged or rigid membranes and straps immediately. Always use original Sundström parts to preserve equipment value. Always replace the valve covers along with the exhalation membranes.
Practical FAQ
1. How often should the respiratory membranes be replaced?
According to the maintenance schedule, an annual visual and functional inspection is recommended. The membranes must be replaced at the latest if they exhibit hardening, tears, or sticky residues to guarantee proper airflow control function.
2. Can I use the SR 200 full face mask if I wear glasses?
Standard eyeglass temples breach the seal line, causing severe leaks. Sundström provides the specialized spectacle frame SR 341 for this purpose, which fixes directly inside the mask and accommodates prescription lenses without compromising sealing security.
3. What is the difference between the glass visor and the polycarbonate visor?
The laminated glass visor (SR 365, Class 2) is extremely unsusceptible to aggressive chemical solvents, wiping actions, and mechanical abrasion—perfect for standard coating tasks. The polycarbonate visor (SR 366, Class 3) provides superior impact resistance against heavy fragmentation risks but is more sensitive to chemical solvents.
4. Why do I need to use pre-filter SR 221?
The pre-filter traps coarse particles and dust before they reach the actual particulate filter (P3 R). It does not function as an independent protective filter but significantly extends the operating life and cost-effectiveness of the primary filter.
5. How can I tell if my gas filter is saturated?
As soon as you notice the distinctive smell or taste of hazardous chemicals, or if irritation occurs despite a correctly fitted mask, the filter must be replaced immediately. Ideally, establish fixed replacement schedules based on operational exposure measurements.
Conclusion
The Sundström SR 200 full face mask with glass visor represents a premium investment in active occupational health and safety. Given the uncompromising solvent resistance of real glass, combined with unmatched wearing comfort and straightforward maintenance, it serves as the ideal tool for professional coaters. When donning and cleaning workflows are executed consistently, this system provides dependable safety at the highest industrial level.
