Venting my spleen... or atleast my airbrush

Working in HVAC has definitely brought more info to me than I would have been privy to without other people with experience related to what I’m planning. So, what the spray booth really boils down to what is known as a filter rack and have a spring loaded door for easy filter replacement. This particular fitting is pretty easy to build as I’m told by the more senior guys in the shop. From what I see it seems to be the case. I just need to figure out what fan I’m going to buy and then install inside. Looking at the specs that are provided on the fan for the BV300SD there are plenty of units to look at and consider with care given to the relative noise and approximate size.

Something else I’ve thought about is the filters used in videos I’ve watched. Realistically for me the replacement of these filters would be a pain as they look to be a general poly fiber material, the likes of which you’d use in a fish tank, with “bird wire” mesh covering them. I’ll be ditching the poly fiber idea. I’ve seen the ventilation of pharmaceutical plants and office spaces during my security work in the past and I know what kind of pain it might be to make it economical on the small scale. I’m going to be using pleated filters used for home heating. So far the MERV 11 rating catches all the overspray from my airbrush and I’ll stick with that. The size will depend on the fan motor and rack area. Premade filters will be a great boon as I’ve taken other filters and cut them to fit my small portable Chinese made spray booth.

Now I need to get info on the ducting as I think a hose fitting and a hole for the switch on the side will also need to be planned for in future for plotting on the plasma cutter. The other fittings like a handle and rubber feet I can probably add with self tapping screws. This might be a good time to learn about electrical wiring as I need to have it run on something other that an orkish Gestalt field.
