MSR are self-contained chambers installed strategically at entrances to clean rooms and other controlled environments. They minimize particulate matter entering or exiting the clean space to mitigate the risk for cross-contamination.

Personnel and materials entering or exiting the controlled environment are “scrubbed” with H14-filtered air by high-velocity air jets running at 18–30 m/s (3543–5906 fpm). Contaminated air is then drawn through the base within the unit, filtered and recirculated.

MSR is the pioneering company for the manufacture and construction of clean room air showers with different applications in the following areas:

• Micro-electronics
• Semiconductors
• Pharmaceutical
• Spray painting
• Laboratory animal research
• Food markets
