Fan set up for a paint booth

[porschercr]

I'd like to get some thoughts on a paint booth fan set up.

Here is what I know.

Voltage (Adaptor)AC 110V

Frequency50/60Hz

Working VoltageDC 12V

Current1.6A

Airflow9m³/min

Fan Power25W

Would that be enough to exhaust lacquer and enamel fumes, without any issue? I would of course have duct work.

Booth size would be  22" (W) x 18.9" (D) x 14.1"

On the exhaust duct hose, how long, diameter of the hose and is it level or elevated are also things to consider. One suggestion on the hose. I found that the aluminum exhaust duct hose that I found at Home Depot works great and is relatively inexpensive. The hose was originally designed as a universal vent hose for a home hot water heater. Should the filter start getting plugged up or the hose has a long run you might start getting paint fumes back out of the spray booth.

To me that's not a lot of blower, think shorter distance, free flowing runs. Many portable booths, not much larger than that, use dual blowers. Just FWIW. I'm not saying not to use it but just to use it sensibly. Some folks add a squirrel cage blower to the venting, especially for longer vertical runs up to basement casement windows.

I think we would need to know more about your setup to advise any further than that. Any more suggestions are shots in the dark hoping you can apply what is stated. Installation specifics help. Is the venting level or a big rise above the booth, or drop for that matter ?

Simply judging from the fan's power, it won't be strong enough. In my current paint booth, I use a ~75 Watt blower from a kitchen hood, and it's marginal. I have a 150 Watt blower waiting to be converted into a paint booth. I too use (acrylic) lacquers, and you really need a good paint booth for those.

Another thing is the ducting. The flow resistance it creates is expressed as 'back pressure' and reduces the flow. Search on 'blower back pressure graph' or similar to see what I mean.

Using OSHA rules for paint booths, plus the dimensions of your booth, you can calculate the required flow.

Thank you all for the comments, I've decided to forgo what I was going to purchase. https://www.amazon.com/VIVOHOME-Portable-Airbrush-Lights-Filter/dp/B08CKSJNP3/ref=sr_1_2_sspa?crid=UX8QHDBXRDAC&dib=eyJ2IjoiMSJ9.mX0OCxlBdE_nJHnWKuPGkEjmG6bv3v-e3QZ4aJlnIoH4758QMqExpmYesLqE4jb2rBbCWZwNzb0QHxhWiVS2m8OcpwxAYhcjhCe724W998aeMZgkI727LOf2lTtOOjMASjLiyTsFtl-a9_PwEyCOBaMFvWr39nxX5ij-W5yXEfPBH2veAe5vbQ47MiLdD8cbQfYyKh97UW2YrMuJwnZPxtcfyOhkO9TWsIePxBJob46c_tzRnunTylz8hfWam1fT6LWuyGvN-lMw_bBkpus-ZEiAnfeJqgLHyuTqwgs803A.j6KT6T8zbGEtTzN8bt9EaXonpt4y2VXDnOQoS2c5Ko4&dib_tag=se&keywords=VIVOHOME+paint+booth&qid=1718851178&sprefix=vivohome+paint+booth%2Caps%2C172&sr=8-2-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1

 

My current setup, (cross draft) is with a bilge blower, and works fine. Just need to rehab the structure. 

Thanks for the link Rob.
