Fume collection -laser cutting

[billvoughn]

Hello,
I have a question regarding a fume/particle collection system for my laser working with cutting some mild steels, stainless steel and also with ceramics. The working space is about 29Dx24Wx30H in (about 14.5 cubic feet).

I've been trying to find some exhaust blower to work for those aforementioned conditions. Given the fact that there will be some carcinogenic agents when working with mild and stainless steels, what kind of blowers should be used? The min cfm I am looking for is 170 cfm (air exchanges every 5s). I wonder whether it is enough. I should not worry to much about the fume system when working with ceramics, right? The main concern then will be particles?

The laser is located closely to a fume food so I am not looking for a complete duct system. But any suggestion would be highly appreciated.

Thank you for your help and Merry Christmas to all,

-B.

I don't have an answer on your flow requirements, but can caution you regarding ceramics. Processing of them will emit fine particulates and the concern here is prolonged exposure to them can cause silicosis. Thus I would suggest that you do have an exhaust or collecter when processing ceramic or silica-based materials.
