Vertical laminar air flow

Vertical Laminar Flow Unit is designed specifically for product protection. The Cabinet is a clean bench which provides ultra clean sterile HEPA filtered class 100 air in an isolated area for operations requiring a particulate-free environment where the highly sensitive process activities are carried-out. The Vertical laminar air Flow Unit draws air in through the top of the unit through a pre-filter, through a plenum and vertically down over the work-surface and past the lap of the operator. It has the advantage of not pushing air into the face of the operator as in a horizontal laminar air flow cabinet. The laminar air flow cabinets are used for work with low-risk substances and materials, when protection of working material from environment is required or work with item requires a sterile working zone. Cabinets are used for equipment of local workplaces in medical, pharmaceutical and other institutes with high requirements for air cleanliness in the working zone.


High product protection by provision of ISO Class 5 particle free work area.

Able enough to handle critical process.

Proven protection for the samples and processes.

The work area is continuously supplied with positive pressure HEPA filtered vertical air flow.

Vertical unidirectional airflow peed prevents contamination from operator and environment to work area.

Laminarity of the flow handles cross contamination between the items in the working space.
