I have been spraying with an Astura Eco/S gravity gun for years. My 60 gallon 2 cylinder compressor is good for 15 CFM in the PSI range HVLP guns operate so I have enough air for a wide range of guns.

I broke the needle and need to buy a new one, along with a new air cap as it’s just worn out. I’ll rebuild the Asturo gun but also started looking at adding a pressure fed or siphon gun to my lineup.

The C.A.T. guns seem like a good option. The Qualspray guns also look good but I don’t like the scenario of having to buy replacement reparts from Homestead alone… single source anything is problematic. The 3M (Accuspray) 125 gun has a delrin body buy it’s not clear to me what the advantage of that is.

My question is: what would you recommend for an HVLP conversion gun that I can spray general woodworking finishes with? I don’t want to spend more than $500’ish and would like to get feedback on how easy it is to clean the guns, availability and price of replacement parts, and most importantly, how does the gun setup and shoot.

My first question is are you doing this as a professional using a spray gun a lot or as a sometimes home woodworker?
$500 is a lot of money for a sometimes use. If you are a home type woodworker I would recommend an HVLP gun I use and often see used in some of the shops on the Velocity channel (an automotive “rebuild” program. It is also sold at Rockler for twice the price of the link below. I have older (1970’s) Binks and DeVilbiss siphon guns and this HVLP dun is of superior machining and I swear by it for a beautiful fine spray. And if you are a professional, I wouldn’t knock it until you have seen it and tried it.

I like the Porter Cable PSH1 gravity feed. It is my go-to gun for lacquer and poly.
You will have $400 left over though.

I also have the Wood River gravity feed gun. It looks identical, but doesn’t come with a pressure regulator.

I also have the gun Planeman referred to. It is very similar to the others, but I haven’t used it as much.

I already have a gravity gun (the aforementyioned Asturo Eco/S). I want to add a siphon or pressure fed gun.

Nick, I have been using an AccuSpray 12S for the past 6 years or so. I spray Target Coatings products exclusively so YMMV. I am very satisfied with this gun. It has never given me any trouble whatsoever. I think the advantage of Delrin is that finishes don’t stick to it. I spray soapy water, then clear water, then DNA through it to clean it and that is all that has been necessary. I will let the finish sit in the gun for up to 4 hours before cleaning it. I haven’t need any replacement parts yet so I can’t answer that question. I usually just turn the finish and air knobs 1.5 to 2 complete revolutions to test and adjust from there if necessary. I think the advantage I have is using the Target products all the time so I don’t have a lot of fiddling to do because of differing viscosities. HTH

Thanks Art.

I also shoot a lot of Target product (EM9000), but lately have been using General Enduro-Var. Both have similar viscosity so my gun settings rarely change.

The delrin body in the Accuspray guns caught my attention and I was hoping the feedback would be that they are easy to clean. I can’t say that the Asturo gun has been a big chore in this area but once every 4-6 weeks I need to tear it down and give it a good cleaning just to get all the material that did stick to the aluminum. I’ve been meaning to switch over to the PPS system, maybe this is a good opportunity to do that as well.

Nick,

My primary gun is an Iwata LPH-400LV (gravity feed), and it is very, very, very good. My second gun is a CAT pressure feed, and it is also excellent. Both guns are near the top end of your price range

The Iwata is a lighter gun, nice when having long spray session. It will spray everything but latex/acrylic paint with fine atomization at low pressures. I’ve had no issues with internal build-up in the 4 years I’ve had the gun, although I clean thoroughly after each session. The controls for fluid and fan work through a wide range, and have very predictable adjustment.

The CAT is a bit more versatile in that the pressure feed helps with the really thick finishes. I don’t use it as often due to the pressure setup being heavier and needing more cleanup time. But the spray is as flawless as the Iwata.

And if you haven’t gone to a.disposable cup setup like the 3M PPS, you should. The ability to spray with the gun at any angle is very useful.

Thanks Mark.

Are you using the PPS system with the CAT gun? Also, what CAT model are you using? I’m curious to know how much more cleanup effort is needed compared to the Iwata. Thanks again.

Nick,

The CAT gun is the Fe-Line LCFM. I’ve got a big compressor at the shop, but the low CFM spec is useful for site work.

The PPS system for the CAT is a pressure system, here http://3mcollision.com/3m-pps-type-h-o-pressure-cup-16124-large-1-cup-per-box-2-boxes-per-case.html. Gun cleanup is harder because you can’t just swap out to a.standard cup and run a bit of water or lacquer thinner through. Otherwise, disassembling the gun for cleanup is the same.

Thanks Mark. Very helpful.

I’m going to go with the CAT Lynx L100H. I shoot waterborne finishes 90% of the time. The all stainless steel passages is a good idea. I’m also going to upgrade to the PPS system, which puts me over my budget but is worth it.

You certainly won’t regret going with the PPS system. Despite that they’re marketed as disposable, you can rinse and reuse the lids and cups. Rip off the filters built into the lids after the first use, as they tend to clog after the first use. Just make sure you use strainers when filling the cups.
