A good unit of HVLP turbine system i have been seeing goes close to $1k. Mine is an older $150 deal. With a better unit it probably would be a different story. I am going to see a compressor today. Seller listed it 30 gallon 5hp, if it turns out to be a decent unit i may grab it set it up. i believe oilless direct drive units are more desirable. I dont know the CFM rating and i hope its written somewhere on the unit. I let u guys know if i get it and we take it from there to figure out the rigt set up this time. Thanks |

Oiless direct drive units are too noisy for me but I have never seen a 5HP oiless compressor. 5 HP compressor will need an AC 240V supply. Each HP is about 750W. _________________ Steve

Hi i went over and picked up the compressor, a CL deal, 5 hp 30 gallon. Plugged in and started to demonstrate. Tomorrow i will hook it up and go over the components to make sure it operates without an issue. The tag says
9.1 SCFM at 40PSI
7.1 SCFM at 90PSI
120 VOLT/240 CAPABLE
125 PSI MAX
Single Cyl/Oilfree
Do i need the spray gun type that is being referred "conventional"? |

Check the specs
on the gun. It will tell you the cfm at psi it needs. You really need to do more research on painting a car via pro you tube or other painting sites. This info is all over the internet. We can help but this is not a great place to learn how to paint your bus. The
painting forum on the samba has a
lot of info. BTW all the turbine advice you have gotten is not from folks who
paint cars, rather furniture. I know
of zero car painters who use a low dollar turbine unit. _________________ Dave O

Hey westina this morning I wrote great missive in regard to your issues. It took me about an hour to compose, then i hit enter and it all disappeared.
I'm not doing again. You will figure it out. _________________ I succeed because I fail. |

I know the feeling happened to me few times. No worries. Tomorrow, i expect to be in business again. My mistakes/lack of preparation caaused me to waste some paint material and time. |

I honestly think that turbine system correctly matched to the gun/needle/tip would have worked. I also agree there are benefits such as no overspray, no fume, dry air...But at this point, compressor seemed to be a more proven method to me. BTW that video helped to understand some basics

Westina,
Most likely you have missed what I have stated. For a 120V compressor, the most it can delivered is 2HP as each HP needs 746Watts. 2HP is 1492 watts and if you use 125V supply, you will need 11.9A. The starting current of the motor is much higher than 11.9A. Standard outlet can give you 15A (or 20A if you use a 115V 20A wall plate and wiring ). So if you compressor can use either 115 or 240V, your motor is only 2HP as you will not get higher HP by changing to 240V. The old way they used to spec the compressor is to state the HP of the motor when it started to stall so you get a higher HP. Read the printing on the actual motor itself and you will find the true HP of the motor.
However, the compressor you bought may still work for your gun as long as you limit the spray pattern. Buy a pressure gauge that mount at the inlet of the gun and adjust the compressor output to the gun psi spec ( at the new gauge and not at the compressor output ) when the trigger is pressed. . _________________ Steve

You are being optimistic. I think they clamp the motor shaft in a #900 vise and record the amperage at the moment it bursts into flames. Anybody who thinks their 120vac shop vac pulls 5hp is deluded. That's why you need the pressure gauge at the gun inlet so you can actually know what is happening. I also recommend you run the gun with a solvent for as long as you think you need to maintain a constant spray pattern to see if the compressor can actually produce the necessary volume at pressure. You may need to gang some additional storage in the form of dead hot water heaters to get what you need. |

When you are done with them fill them with natural gas and set them off as redneck Roman candles.
Don’t transport them full, it’s dangerous. The can fall over and pinch toes. _________________ .ssS! |

Hi. I have notice what you have said about the HP rating, its just what it states on the unit, thats the biggest one i can get. I am a one man show, loading, unloading even though it was a smaller unit, it was a biatch. This is it. Whatever result i get, i ll settle with it. I can just name the van "zebra" and claim i did an art work. |

i also swinged by the HF and grabbed the chepo purple gun $10 with a coupon. I did this because its not an air hog like the one i have. 6CFM at 40psi.
https://www.harborfreight.com/20-oz-high-volume-low-pressure-gravity-feed-spray-gun-47016.html
In line regulator, few connectors and a moisture filter...I have some sanding to do and after that i ll experiment some and try to figure out what works best or if its going to work at all. |

Dave, while there are indeed low dollar "turbine" paint systems on the market (remember the old Kirby or Electrolux vacuum ads where a painting spray gun was part of the accessory package?) I have indeed painted vehicles with a turbine system....... with very good results. Of course my unit was a $2,000 spray system when new.

Turbine didn't go well for me. Didn't have the right nozzle/needle set for the spray gun. Long story short we have a compressor now.
i have set the whole system today. Compressors tank holds up air really well around 120psi. Took the chepo gun apart and cleaned the famous silicon/grease and installed the inline valve with gauge and the disposable moisture filter. I have wet sanded most of the van with 600 grit, according to the paint manufacturer. Tomorrow i expect to finish the prep work and practice on my spray/gun adjustment. |
