For evidence storage, forensic analysis, tissue inspection and other investigation practices where airborne contamination control is vital, why not bring ultra-clean air to the worksite with a system that is mobile, reliable, flexible, quickly installed and in minutes obtain cleanroom conditions for your procedures. From enclosed mini-environments to creating clean air zones to setting up positively pressurized portable verifiable ultra-clean chambers, Airex is your answer. A Certified HEPA filter with 99.997% efficiency at particles greater than 0.3 micron is used with extended life provided by an activated charcoal prefilter. For use where hazardous materials are being handled and user safety is critical, a negative pressurized chamber can be added to trap hazardous pathogens such as anthrax, keeping them out of the workplace.
