The first stage of the tandem version is our mini porter cyclone which collects nearly 100% of powders in the air stream. The benefit is prolonged vacuuming without filter cleaning. It is connected to our 60 litre vacuum, has a 2 metre x 38mm anti-static hose, 700mm long nozzle & is supplied mounted on a robust mobile platform for complete manoeuvrability. Other vacuum crevice tools, brushes etc. are available to order.
