![]() ![]() ![]() Maintenance of a laminar flow hood device with a HEPA filter involves a cyclical filter test and periodic replacement. In order for a cleanroom to continue operating seamlessly, the equipment needs to meet the sterility levels requirements. A HEPA filter can eliminate 99.97% to 99.99% of particles that are no larger than 0.3 microns. Possible applications include IV preparation, non-biological tissue culturing, electronic or optics assembly, non-hazardous drug compounding, and parts inspection. It’s suitable for an ISO 5 cleanroom environment (Class 100) as well. In a horizontal cabinet, air blows directly toward the operator. Vertical workstations can be used for liquid/powder filling, washing operations, transferring samples from one place to another, and storage of material under Class 100 environment (meaning, an environment that contains less than 100 particles 0.5 microns per cubic foot of air). They can also vary in size to suit a specific application or the size of the product.ĭepending on the airflow direction, they are categorized as vertical or horizontal. These systems remove 99.97% of the particles from the air, such as dust, pollen, mold, bacteria, and any airborne particles with a size of as little as 0.3 microns.Ī laminar flow hood with a HEPA filter can be used for general lab, particularly, to filter the air for medical, pharmaceutical, electronic, and industrial use. ![]() The filtration mechanism consists of a pre-filter as well as a high-efficiency particulate air system (or several ones depending on a model). In essence, air enters the filtration system from the outside and gets exhausted across the working space in a unidirectional airflow. The working principle of a HEPA filter inside a laminar flow hood is as follows. The reason is that filtered air over the work area keeps particle sensitive samples “clean”, i.e., free of contaminants that could damage them. In industry, these are often called clean benches.
