Usage And Functions Of Laminar Air Flow Cabinet

Laboratories need to carry out some specialized tasks and experiments, which include pharmaceutical, medical, biotechnology, etc. These specialized tasks need dust-free and sterile areas. Here comes the role of the laminar airflow system to make the working area free of particles and contaminants. This system provides continuous and uniform airflow in both velocity and direction.

Uses

Laminar air flow cabinets are equipment used to give unidirectional airflow in a restricted designated space. They blow out air via a filtration system and exhaust it across the work surface to make the working area contaminant-free.

Such cabinets are enclosures made to flow HEPA filtered air with uniform direction and velocity and to sustain sterility and avoid cross-contamination.

Functioning

Before relying on laminar air flow cabinets, make sure you understand the functioning. A laminar air flow cabinet involves a fan, a filter pad, and HEPA or High-Efficiency Particulates Air Filter). Here, the fan is used to draw air via a filter pad, where the dust is trapped. This pre-filtered air crosses via a HEPA filter and contaminants like fungi, bacteria, and microparticles are eradicated. This way, the contaminant-free and sterile air flows into a working environment to make sure the entire process can be done with no contaminants. Depending on the need, one or more HEPA filters are included in these cabinets.

While choosing a laminar flow cabinet, you must consider factors like work type, work surface design, clearance requirements, process location, and operator safety.
