Laminar flow hood: OS-N TechGen


The OS-N TechGen provides a Class ISO 3 workspace for perfect sample protection.

Air is drawn in from above through a pre-filter which limits clogging of the main filter. It is then blown horizontally into the workspace through an HI14 HEPA filter situated at the rear of the workspace.

The HEPA filter is fitted with a laminar flow diffuser in order to optimise homogeneous airflow velocity within the workspace.
