For applications that require a particle-free, compact clean room environment, the 40” Wide Portable Clean Room Hood may be an optimal solution. This positive-pressure benchtop hood utilizes a vertical laminar flow pattern and provides an ISO Class 5 clean room enclosure. A dual-stage filtration system comprised of a pre-filter and main filter supplies purified air into the hood to protect the process. The main filter is typically either a HEPA or ULPA filter depending on the efficiency desired. The HEPA filter is up to 99.97% efficient on particles 0.3 microns and larger, while the ULPA filter is up to 99.9995% efficient on particles 0.12 microns and larger.

This unit has been used for a variety of applications that require a clean environment, including stem cell therapy practices and other medical applications, compounding, tissue culturing, data recovery, clean room applications, manufacturing, cleaning processes, and much more.

This unit is equipped with a Variable Speed Controller for air volume management and a fluorescent light for interior illumination. A UV light is also available for sterilization purposes. The 40” Wide Portable Clean Room Hood offers energy-efficiency and quiet and low maintenance operation for a variety of applications that require a compact, particle-free environment.
