Air Science Purair Laminar Flow Cabinets

from $1,699.00

Purair® FLOW™ Series laminar flow cabinets are designed to protect the work surface, products and materials from particulate contamination. Room air passes through a HEPA (High Efficiency Particulate Air) filter then uniformly by laminar flow through the cabinet interior to protect the work from unfiltered air. The airflow is oriented to exhaust airborne particulate introduced by the user.

The Purair® FLOW™ Series product line employs the Air Science exclusive Multiplex™ HEPA Filtration Technology to sustain the contamination-free environment.
