An old benchtop downdraft booth was being used for mixing and weighing processes.
However, this was in very poor condition. Additionally the extracted airflow was drawn down into a grille on the bench just in front of the operator and a lot of valuable product was being dropped into the filter and lost.
A bespoke “backdraft” style downdraft booth was installed to draw dust away from the operator. Two-stage particulate filtering provided excellent operator protection and improved working conditions.
This had a much higher design airflow to ensure the heavier contaminant was adequately controlled.
