Horizontal Laminar Air Flow Bench Diagram
99 99 particle free air is forced in a back to front direction across the work surface.
Horizontal laminar air flow bench diagram. Read more about validation services offered by germfree. 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 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.
These clean benches provide product protection and were originally designed to provide a particulate free environment for manufacture of semiconductor components. 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. 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. Air flows in a uniform direction with a constant speed within the enclosed bench with little to no crossover air streams.
Horizontal laminar flow hoods. Horizontal vs vertical laminar flow hoods. Advanced horizontal laminar flow station he bz series hood is designed for the handling of materials in a sterile working environment. The work area is bathed by positive pressure horizontal laminar flow air that has passed through a high efficiency particulate air hepa filter.
Laminar flow hoods are designed to protect samples and parts from particulate contamination. Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation. The clean bench provides a class 100 m 3 5 environment. The unique design concept of the lf horizontal laminar flow clean bench consists of separate plenum and table.
What is laminar flow bench. A laminar flow clean bench provides a working environment that has its own filtered air supply. 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. 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.
Air is drawn through a hepa filter and blown in a very smooth laminar flow towards the user. Laminar flow benches and hoods. Laminar flow cabinets and booths. 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.
