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 Reverse Laminar Airflow Bench finds a major application in sampling and dispensing. Majorly 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.
Reverse Laminar Air Flow Unit operates on a re-circulatory airflow principle providing containment by air movement. 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.
Reverse Laminar Air Flow Unit is with a variety of standard dimensions also our cabinet can be custom engineered to any size. Reverse Laminar air flow are available in powder coated Mild Steel, SS 304 / 316 / 316L or a combination of both.
