The DraftMax Ultra is a workbench that provides extraction and filtration for welding and grinding applications.
The DraftMax Ultra features a work grid, a three-stage pre filtration system for optimum spark arresting and two self-cleaning main filter cartridges. Both pre and main filters have pull-out dust drawers underneath. The filter cleaning system starts automatically each time the fan is switched off (offline cleaning) and also when the pressure drop reaches a certain maximum value during use (online cleaning). The filter cartridges are individually cleaned from the inside by compressed air-shots. An integrated buzzer indicates when the filter cartridges need to be replaced.
For welding and grinding applications the DraftMax Ultra should be fitted with a backdraft kit for optimum division of the extraction capacity (approx. 80% backdraft, 20% downdraft). Filter exchange and service (except for the membrane valves) can be affected from the front side.
This unit is similar to the DraftMax Basic. In addition, cleaning starts automatically as soon as the fan is switched off. It also offers the possibility of an automatic start/stop device making the unit even easier to operate. This unit monitors the compressed air and pressure difference permanently to ensure optimum extraction.
