The 18 in. wide Portable Clean Room helps protect sensitive applications from outside contamination by creating an ISO Class 5 Cleanroom workspace. This system creates a positive-pressure environment by supplying filtered air to the hood in a vertical laminar airflow pattern. The compact and portable design makes this system ideal for field testing applications. Other applications suitable for this PCR include IV bag infusion, stem cell therapy, optics assembly, laser cleaning, tissue culturing, and many other laboratory applications that require a sterile work environment. Approximate Air Volume: up to 111 CFM. Filters Available: HEPA Filter [up to 99.97% efficiency on particles 0.3 microns and larger] and ULPA Filter [up to 99.995% efficiency on particles 0.12 microns and larger].
