Is there any advantage to using a turbo driven HVLP over a compressor driven HVLP? and if so, how bout some of your favorite recommendations.

Thanks for posting this John,

You beat me to it because I've been contemplating the same thought. I've been using a compressor driven unit.

Waiting to learn

I'm only surmising, but my thought is that one might have less of an issue with hot air with a compressor version vs a turbine.

As you likely know John, Gravity has nothing to do with the difference between turbine or conversion HVLP equipment. Gravity and or Siphon refer to the way the gun receives the media. Gravity feed the gun has a reservoir above the intake and gravity allows the media to flow into the gun. Siphon feed the gun supplies a siphon suction line into a reservoir below the gun and draws the media from the reservoir via that suction line. Either type of feed is available on conventional HP, conversion HVLP and turbine HVLP guns

HVLP Turbine units provide warm dry air and are not subject to air volume drops. Some are available with turbine speed control. Warm air is a good thing, not a bad thing at least up to a point. Turbine units require no additional moisture filtering. They are relatively small compact and very. The guns are simpler chambering and mix components and IMO simpler to keep clean.

My recommendations are Fuji Q4, MiniMite3 and or MiniMite4. MiniMites’ are the same as Q-series except no silencer.

Conversion guns come in a wide range of quality the use compressed air. Someone use to conventional spay guns will feel more at home with a conversion gun. Conversion guns are a bit more finicky to set up. They have a more complicated and smaller porting and are tougher to clean IMO. The also require a water filter upstream of the gun to prevent compressed air condensate from entering the gun.

By the way gravity feed is the way to go!!!

Right you are Michael, I do know that and should have just said the difference between turbine driven and conversion. Anyway, I have been using a conversion system for most of my building career and the moisture problem is precisely why I am thinking of going to the turbine. Thanks for the inputs guys!! I'll take a look at your recommendations.

John,

I've been using a syphon feed Turbinaire HVLP system (which has a variable turbine speed) for many years and still love it. Over the time it takes to spray a guitar, the air doesn't get noticably warm, but I have the optional cooling section of pipe fitted to mine. Everyone else I know who has a Turbinaire loves it too.

Cheers,
Dave F.

I use a hvlp siphon feed gun with a 80 gal. tank compressor.and don't have any problems with moisture.I always leave the lines and tank drain open 24 hrs. before i spray and use a trap at the tank as well as a filter at the gun.
