When welding, grinding or dust source capture is necessary away from a fixed work station, both Maxiroll and Maxicart units are easily moved to the desired location with the help of swivel casters and push handles. Cartridge cleaning is a snap. Simply push the palm button to discharge the compressed air from the integrated air tank. Both units have large dust trays at the bottom and are emptied when needed. Backward inclined fans deliver great air volume while the foam insulated steel cabin ensures quiet running. MAXIROLL and MAXICART portable units can be equiped with Maxair arms. The units may also be connected to a ductwork arrangment for remote source capture.
