Laser airflow rates

Hi All

I’m interested in what the airflow rate is needed, even as a minimum, as I’d like to extract straight outside.
I have 25mm diameter hose that I’d like to hookup to the laser head.

Thanks in advance.

Didn’t see initially this was talking about extraction directly from the laser head. The flow from the fan is likely in the ballpark of 10cfm, assuming it’s roughly a 4015 sized.
