We have a new laser cutting machine being installed shortly.
We chose not to purchase their extraction system
as it is installed in the factory right next to the laser
and does not remove the odour.
We will also be cutting a considerable amount of stainless steel & this should definitely be exhausted outside. Unfortunately the agent does not have any spec on what the extraction package was.
It looks like a 1 metre x 1 metre x 2 metre high box with
plastic cartrige filters 6 - 9 on each face about 140mm dia & has pulse cycle, is for dry solids only
Agent recomends 4000 CFM & outlet is 225mm OD-this doesn't
sound right to me i think they mean 4000 CFH ?.
they don't have a presure spec, the cutting table is
3 metre x 1.5 metre grid & is sectioned into 4 or 5 zones
along the 3 metre way & extracts only on the zone were the cutting is taking place.
(A lot of laser shops we visted did not buy the extraction
system & just extracted straight out the roof.)

Anyway they want $20,000 USD for their system.

some advice would be appreciated
