Fine powders such as flour, sugar, toner and metal dust load a filter fast. The BL 20 JC DEX combines the sealed brushless head of the BL range with a large antistatic cartridge and the JetClean system, so the operator can clear the filter in seconds without opening the machine inside the zone.
To clean, the sliding damper is closed over the inlet and the flap on the head is opened: outside air rushes back through the cartridge and drops the dust into the 20 litre stainless bin. An H14 secondary filter sits downstream as the final stage.
