Garmat USA’s AlumaSAFE 50 provides the isolation for welding or other aluminum repair processes. The Aluma-SAFE 100 and AlumaSAFE 500 expand on isolation by adding a fan unit that allows both of these models to be used for grinding operations as well. The AlumaSAFE 100 is a non-pressurized system featuring recirculating crossdraft airflow, Fortex spark arrestor panels and three stages of high-efficiency filtration including HEPA. The AlumaSAFE 500 pressurizes the unit and adds a fully lit ceiling for an improved working area.
