While there is no universally standard “MAS-22” microbial air sampler, you are likely referring to the specialized MAS-100 NT 6022, the leading Swiss-engineered system for indoor air quality and ventilation hygiene. It operates on the Andersen impaction principle, drawing air through a perforated lid to capture airborne microorganisms for testing.
The MAS-100 NT 6022 features:
- Airflow Rate: 100 Standard Liters per Minute (SLPM)
- Accuracy: ± 2.5% with a real-time regulated radial fan
- Compliance: Certified specifically for HVAC hygiene inspections in accordance with VDI 6022
- Capacity: Compatible with standard 90–100 mm Petri dishes and 55–60 mm contact plates
If you need to perform air quality checks according to European ISO standards or GMP guidelines, active air sampling is required to meet regulatory minimum volumes, typically 1,000 L in controlled environments.
