I want to get into spraying and have decided on an HVLP turbine unit - details TBD. I plan to spray waterborne finishes with the exception of shellac, which would be done in the garage or outside.
The main obstacle I have is where to do my spraying. My shop is in an unheated/uncooled garage and I don't really have the space for a spray booth. I also don't want to deal with moving and storing a tear-down booth.
I have a room in my basement that is well-lit, dry, and available. I would like to set up a booth in there, but there is no ventilation. Ideally my booth would be 5' x 5', with 7' ceiling. I can make it open at the entrance, or enclose it.
I could run a duct outside from this room with a dust collector or some sort of inline fan to pull air out, but I don't like the dust collector route because of the noise. I do not have the space for more than about a 6" duct (i.e. I can't put a big fan in the wall).
Wearing a respirator with the appropriate cartridges is a given, and the room is well enough sealed and insulated that I am not worried about toxic stuff spreading elsewhere in my home.
My questions are: would a 200-300 cfm inline fan provide enough airflow to vent the harmful stuff? Would it offer any assistance with overspray? Would two inline fans increase the airflow? Anything else I should be thinking about? Any other suggestions?
Thanks.
