Multi-layered clean-film full sticky layers form mats that effectively capture dirt and dust from foot-traffic and equipment wheels before they enter the controlled environment. Each of the numbered layers of the mat peels off easily to reveal a new clean surface. Independent testing shows that mats represent the most effective particle reducing system for significantly reducing traffic-borne contaminants, removing up to 95% of particles at the .30 micron range. An Acrylic sticky is used which does not support microbial growth. Mainly used for electronics, computer, instrument, medical- device, pharmaceutical, aerospace and nuclear industries.
