The Kemper Dusty has a high vacuum ability making it ideal for welding smoke extraction.
Using one of the 45mm elephant hoses to connect to and gain fume extraction at source from a MIG torch or when required the possibility exists to operate with either one or two suction nozzles (not included) - for temporary / occasional extraction in say a repair environment or for mobile use when and where a full time extraction MIG torch is not used or required. The primary inlet is used for a single inlet hose and single extraction nozzle / fume extraction MIG torch the secondary inlet opens when a second hose has been fitted to the front panel which enables fume extraction from both sides of a weld where repair work is being undertaken or it is awkward to gain access with a large MIG extraction torch.
The Kemper Dusty has been designed for low to medium amounts of dust.
The filter may be cleaned manually, the filter is KemTex® ePTFE , the fact that the filter may be cleaned manually makes the Kemper Dusty very economical. The very efficient filter membrane means that manual cleaning is safe and contamination cannot be blown back into the work area. The Fume extractor indicates when the filter requires cleaning, when the filter indicator shows that cleaning is required the top is simply un-clipped which removes the motor and then an airline is used to simply blow the filter clean, the dirt particles are contained and fall down harmlessly into the bottom tray. Once the filter has been blown clean the motor is refitted and clipped to the top, the bottom tray is then un clipped and the dirt particles may be collected and taken away for disposal.
As with a filter unit the filter will need to be changed, depending on use probably every 3 to 6 months.
The Kemper extraction unit has a stepless variable speed control and may be set to suit the extraction application.
Generally the Dusty will be used with a single extraction MIG torch or with either a single or two fume extraction nozzles various shape & size nozzles are available.
Should you decide to fit and use two extraction MIG torches to your Dusty Fume extractor then the filter unit will require cleaning twice as often and replacing more frequently.

Our quick video clip shows welding with the Holch torch extraction "on" followed by the Kemper MiniFil vacuum having been turned "off" so you see the normal fume as a direct comparison, then the Vacuum turned back "on" the close up didn't work as my stills camera doesn't refocus easily. We will reshoot later. The Headux 250C Welder was operating at 230 Amps welding with 1,0mm mild steel ESAB G3Si MIG wire with the wire speed at 16,5 m/ min.
The Holch MIG torch is the MHS350 air cooled version which has the same front end as the water cooled MHS 450.
