Paint gun hose length?

Does having a very long hose to the air compressor have any effect on an HVLP paint gun? I am wanting to setup a paint booth, and the best place i have is the back yard, but the compressor will be in the garage..

Please advise

You don't want the compressor in the same room, they kick up dust while spewing little particals of oil into the air and niether are ok around wet paint.

Milo is right on, I learned this the hard way!! If it must be in the garage vent it outside and enclose the area with plastic when you spray

Yes, Yes, yes the hose length will effect the VOLUME of air needed for an HVLP. Plumb the "booth" from the compressor with 3/4" PIPE and keep your hose (3/8") to a 25ft max for best results.

I built a booth out of PVC tube and cheap clear plastic from the Hardware store.

Attached is the basic layout of the PVC pipe. At the corners where a 90 and a T meet up I just used short sections of pipe and I duct taped everything together. I also screwed eye hooks to the ceiling and tied off the poles to the eye hooks. For a temperary setup it seems to be working reasonably well, and the price wasn't too bad.

I don't mean to hijack the thread but what would you guys recomend for compressor hardline setup, I really don't want to solder anything and I'm only talking about 15ft or so. I've heard people talk about "black pipe" can you use threaded fittings without leaks. I've got a water seperator already I'm looking for a cheap setup for a rookie, I'll only be shooting epoxy primer so I don't think I need a real trick setup. Any Pointers.....?

You want 25 ft MINIMUM with 35 ft or so much better. The air needs to cool off before the water trap so the trap can trap all the moisture. Use galvanised pipe, black pipe is made for gases and will rust with the moisture found in compressed air.

A long hose will cause a loss of CFM from the tank to your gun.

Having incorrect or poor quick connects on the hose will add to this even
more. When you get a hose try stick with a 25ft hose if possible. I use
a 50ft Amaflo 3/8" ID hose with good connectors that do not restrict the
air flow. I found the actual connectors to make more of a difference than
the additional 25ft of hose. You had posted questions on air compressors
before look at that thread for info on the type of connectors to use.

Thanks. X
