Horizontal Laminar Air Flow Bench Diagram

Laminar flow benches and hoods.

Horizontal laminar air flow bench diagram.

What is laminar flow bench. All horizontal laminar flow products are designed to provide product protection by creating a particle free working environment in accordance with eu gmp grade a. Horizontal vs vertical laminar flow hoods. Air flows in a uniform direction with a constant speed within the enclosed bench with little to no crossover air streams.

The clean bench provides a class 100 m 3 5 environment. A horizontal flow hood requires additional depth to accommodate the rear mount filter fan unit with some additional rear clearance to allow air to enter the system. Used in a variety of applications including medical research laboratories hospitals manufacturing facilities and other research and production environments clean benches direct hepa filtered airflow across the work area to provide iso class 5 class 100 virtually particulate free work area for. Horizontal laminar flow hoods.

The bz series of horizontal laminar flow hoods meet or exceed iso 14644 1 federal standard 209e for iso 5 class 100 air and ies recommended practice for laminar flow clean air devices. Laminar flow hoods are designed to protect samples and parts from particulate contamination. A laminar flow cabinet laminar flow bench or laminar air flow hood is a bench or workstation designed to prevent contamination of semiconductor wafers biological samples or any particle sensitive device. Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation.

The lf horizontal laminar flow clean bench is a completely self contained multipurpose vibration free clean bench that supplies a laminar flow pattern of hepa filtered air. All units are nrtl listed with met labs to comply with ul 1262. Laminar flow cabinets and booths. Room air in red enters the system from behind the hepa filter.

With horizontal laminar flow clean benches hepa filtered air flows horizontally across the workspace directly toward the user see diagram at end of this chapter. A laminar flow clean bench provides a working environment that has its own filtered air supply. 99 99 particle free air is forced in a back to front direction across the work surface. Horizontal flow hoods are most commonly used with the more costly vertical flow hoods being reserved for agents that may produce an environmental hazard e g.

These clean benches provide product protection and were originally designed to provide a particulate free environment for manufacture of semiconductor components. Air is drawn through a hepa filter and blown in a very smooth laminar flow towards the user. The work area is bathed by positive pressure horizontal laminar flow air that has passed through a high efficiency particulate air hepa filter.
