Dispensing booth, also know as reverse laminar air flow (RLAF),  sampling booth, weighing booth or down-flow booth, is mainly applicable to pharmaceutical, food and healthcare industries. it is designed to provide vertical laminar airflow to work area, most of air is recycled within booth, partial air is exhausted, so as to make working area in negative pressure state, thus containing particles or powder from overflowing outside of booth when weighing or sampling raw materials are conducted inside booth. More importantly, the negative pressure booth can protect worker’s health from inhaling particles or powders.
