Sorry to thread-hijack but I figured the title was appropriate enough and generic enough to avoid creating another thread....
Does this look like a valid/safe setup for air intake?
Originally I was going to intake from the small window behind the workbench but flu-reversal concerns have me wondering if just running duct for the intake below the bench is a better choice? The workbench will be 5-sided to maximize airflow.
The back alley is long, I could probably get >15ft linear space apart and both duct runs would be straight with no bends.
Thanks!
