It is an ATEX certifi ed vacuum cleaner specifically designed to inertize reactive and potentially explosive metal powders with liquid.
This kind of metal powders are used in laser sintering in 3D printers.
The special liquid bath (water or oil) ensures that the dust that will be aspirated can not react and ignite, or worse, explode.
Inside the tank then, a special float has been placed which interrupts the suction in case the inertizing liquid is absent or too little. This greatly increases the safety of the
machine, and of the operators and its use.
The practical drain tap placed on the tank, allows to empty the machine from the liquid without effort by the user. The parts in contact in brushed stainless steel, in addition to making the appearance of the machine extremely pleasant, guarantees a longer life of materials and an intrinsic safety from the risk of shock ignition.
A safety (or vent) valve is located on the tank to ensure that, when water is used as an inerting liquid, the dangerous hydrogen concentration (developed through
hydrolysis) is expelled if aluminium powders are recovered.
The vacuum cleaner then has a coalescence fi lter that retains any vapours that might be generated as a result of turbulence produced by air refl ux.
