A down draft table for plasma cutting should have local ventilation, rather than table-style ventilation. Also, to handle smoke, a down draft table for plasma cutting should have HEPA filtration.
Yes – with the caveat that aluminum should not be “mixed” with other metals.
Yes – Tri-Mer’s Downdraft Workstation captures virtually all ferrous and nonferrous metal dusts .5 microns or larger at 99.5% efficiency or better
Self-contained downdraft tables are suitable for both carbide and aluminum. The downdraft table for grinding aluminum should be ducted to a wet collector – not a dry system, and it needs a hydrogen release valve. There are economical downdraft grinding tables that have these requirements.
The Tri-Mer Wet Station Downdraft Table is manufactured to aerospace specifications and is engineered for beryllium, titanium, magnesium and aluminum.
The solution is a downdraft table with wet particulate collector. The best down draft tables are 99% efficient at eliminating metal grinding dust hazards – and preventing the respiratory diseases created by those hazards.
The Tri-Mer downdraft table is suitable for all of these; if corrosives are present, polypropylene, rather than mild steel construction, is preferred.
Some downdraft tables would need enclosures – or barriers or silencers. Others well-within acceptable OSHA noise limits, and, are even quiet enough for normal conversation.
