Reverse Laminar Air Flow is designed to provide Class 100 working environment at rest with built in scavenging system to ensure product, operator as well as surrounding environment protection. The RLAF bench finds Major applications in sampling and dispensing units. Idealy used for mixed airflow stream to control the hazardous emission of dust powder during dispensing or sampling process. This ensures to draw powder aerosols away from the operator and the operating environment protecting products and providing safe working conditions for personnel. The system operates on a recirculatory airflow principle providing containment by air movement. The prefilters at the base of the rear wall capture the airborne contaminants generated. Intake velocity at prefilters ensuring increased 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. Reverse Laminar Air Flow Unit is ready available in various standard dimensions also the cabinet can be custom engineered to suite any size. These Units are available in powder coated Mild Steel, SS 304 / 316 / 316L or a combination of both.
