Purair laminar-flow hoods from Air Science, Fort Myers, Fla, are high-efficiency products designed to protect equipment and other contents of the work zone from particulates. The product line includes vertical laminar-flow hoods and horizontal laminar-flow hoods suitable for use with nonhazardous contaminants and when flexible access to the equipment in the work zone is desired.

All hoods in the series make use of the Air Science multiplex ultralow particulate air (ULPA) filtration technology to create a clean work environment over a wide range of applications.

The hoods feature a high-capacity air-handling system that delivers a flow velocity of 80 to 100 fpm, and an ULPA filter pressure gauge that measures filter performance.All models use ULPA filters, which are 99.999% efficient at removing particle sizes between 0.1 and 0.3 µm. Air cleanliness exceeds ISO Class 4 requirements, providing a sterile work environment for aseptic techniques.

The back walls of the vertical-flow hoods are perforated to reduce work-surface turbulence by removing some of the airflow to the rear. All models are equipped with a stainless-steel work surface. They are available in six widths from 24 inches to 96 inches.
