Contamination on feet and wheels contribute over 80% of the particulate carried into a controlled environment (3M Study). Placing a mat outside the entry will eliminate up to 100% of this contamination threat before it ever gets into the cleanroom. This allows laminar flow and filters to work more efficiently. Polymeric matting is designed to attract, collect and retain contamination, preventing particles and microbes from getting into your critical areas. Permanently installed, it is the most effective way of controlling all forms of foot borne and wheel borne contamination.
