Paint booth heat

[Tsadkins102]

I’m renovating a garage right now and I’m trying to determine the best heat for the current setup. I have a 16x26 paint booth with air in from the top and exhaust out from the bottom.

The picture you see is the ceiling of the booth. The ducting that runs to the top is separated. Right now, the big duct in the middle is on its own duct with an hvac blower. The smaller ducts run to other ducts in the rest of the garage and to an opening in another room where I guess a furnace once was. I’m not familiar at all with hvac. But why have two separate duct systems? Don’t electric furnaces have a motor built in? Why the single blower on its own duct? Anyways, I’m wondering what type of furnace I should purchase and what type of system this current set up would be referred to. Again, it’s air in from the top and exhaust out the bottom. One duct has a blower and the other one would have a furnace with an additional blower. Would this just be a way to force the hot air back into the booth?

I'd be careful with paint fumes being around any kind of ignition source.

I would guess it has to do with needing anything electrical in contact with a a paint booth to be explosion proof.

The larger duct isn't necessarily for heat. it more for ventilation to remove the paint fumes from the booth. While the smaller duct would be HVAC. To heat or cool a paint booth takes ALOT of btu's

Many paint boothes I have seen have a heating system, both for maintaining a decent temperature in the booth and for curing the paint. In any event, they are make up air systems and aren't even close to something you could make from regular HVAC stuff.
