down draft vs. water

I am happy to send you some pics, I think the future is down draft table, the future is green, for instance in Europe our colleagues use 99% down draft table...I have been many times at Euroblech in Hannover in Germany, the world's largest industrial trade show I never seen a water table. Euroblech starts next week and I am pretty sure that nobody will have water table, the new environment rules will not allow watertables anymore I think. Sideros Engineering The company I purchased my tables is exhibiting at both trade shows, just take a look of it, ask a quotation if you need.

I have a smaller 5x4 water table and one nice benefit that I didn't even think of is vibration absorbtion. I didn't have the capability to make a real heavy steel frame so the added mass of the wwater has really helped out. I'm able to run detailed work at 200 ipm and high acceleration rates with very little vibration. There is a noticable difference without the water.

I don't see how a downdraft table that pumps the smoke in to the air is that much greener than a water table.

I love being able to pull parts right off the table with bare hands and when I get a tip up on thinner sheet and can reach in and deal with it without fear of burning mayself.

The water tables are fine when the realities are small. WHen you have 3 or more machines with a good turnover, if you stop the machine for 2 days to clean it you loose thousand of $ in maintenance and cleaning.
On the contrary a down draft table never stops working, because there are self cleaning systems, for instance the RAPIDCLEAN by SIDEROS ENGINEERING, which allow you to empty the slag container keeping to work with the cutting machine.
On the other hand The dust collector are perfectly green. For instance, I have 6 Sideros' dust collectors, I keep all of them inside the building and the emission are 0 nano grams per ft2, I checked with my air pollution meter.
In addition They keep warm the building especially in our cold winter ))

Bye see you!!!!
