Purair FLOW Laminar Flow Cupboards

Purair FLOW laminar flow cupboard

Purair® FLOW series laminar flow cupboards are designed to protect the work surface, products and materials from particulate contamination. Room air passes through a HEPA 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.
