Down Flow Booth
NGT downflow booth provides the highest levels of operator protection from potentially harmful airborne contaminants generated during manual powder handling operations such as sampling, charging and dispensing.
The modular downflow booth operates on a recirculatory push-pull airflow principle providing containment by air movement. A clean, constant, turbulence free, unidirectional downflow of air is supplied from the ceiling, suppressing any dust clouds generated during open powder processing, removing and capturing airborne particles from the operator’s breathing zone.
Exhaust air grilles at the base of the rear wall capture the generated airborne contaminants. The exhaust airflow then passes through a series of filtration stages before returning through the booth ceiling plenum. A small percentage of air is discharged from the booth through the bleed exhaust port to maintain the working space under negative pressure, minimizing airborne contamination breakout.
