Reverse LAF

Reverse Laminar Air Flow Unit

sterireverseTM is designed for providing highest level of protection from airborne RLAFcontaminants generated during powder handling operations such as sampling, charging & dispensing.

sterireverseTM provides :

  • Operator Protection
  • Product Protection
  • Environment Protection

 

The downflow booth operates on a recirculatory airflow principle providing containment by air movement.

A clean, constant, laminar downflow of Class 100 air is supplied in workarea suppressing any dust clouds generated during open powder processing, removing and capturing airborne particles from the operator’s breathing zone.

 

The Prefilters at the base of the rear wall capture the airborne contaminants generated. Intake velocity at prefilters 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.

 

sterireverseTM is available in powder coated Mild Steel, SS 304 / SS 316 / SS 316L or a combination of both.
