The laminar flow principle involves double filtration of air through pre-filters (up to 5 microns) and HEPA filters (down to 0.3 microns) for filtration of biological and particulate contaminants unidirectional airflow is drawn from the atmosphere and passed through pre and HEPA filtered on to the work surface. Tabletop covered with laminated sheet or SS sheet (optional) side panels are fixed and are made out of the transparent acrylic sheet. The front door is also made of an acrylic sheet. The superior motor is used for the blower. Laminar Air Flow Vertical Unit is supplied with a manometer, UV tube, and fluorescent lighting tubes.
