Laminar Air Flow (LAF) unit is a specialized cleanroom equipment used in pharmaceutical, microbiological, and laboratory environments to maintain a sterile and particle-free working area. It works by supplying air through HEPA (High-Efficiency Particulate Air) filters in a unidirectional (laminar) flow, either horizontally or vertically, which continuously removes airborne contaminants.
The main purpose of LAF is to protect sensitive processes such as aseptic drug preparation, culture handling, and sterile sampling from contamination. It ensures that the work surface remains free from dust, microbes, and other particles by maintaining a constant flow of ultra-clean air.
