Reverse Laminar Air Flow Unit designed with precision for providing highest level of protection to Product, Operator as well as to environment from airborne contaminants generated during powder handling operations such as sampling, charging & dispensing.
Furthermore, Reverse Laminar Air Flow can be customized to suit the precise requirements of the clients. The down flow booth operates on a Recirculatory airflow principle providing containment by air movement.
A clean, constant, laminar down flow of Class 100 air is supplied in work area suppressing any dust clouds generated during open powder processing, removing, and capturing airborne particles from the operator’s breathing zone. The Pre filters at the base of the rear wall capture the airborne contaminants generated. Intake velocity at pre filters increases to ensure scavenging effect.
A small percentage of air is discharged from the booth through the bleed exhaust HEPA filter to maintain the working space under negative pressure.
