Great video! Normally I have to search around and watch multiple videos to get all the info I need. But this video was all I need. Gravity gun is what I’m going to go with 👍🏻
I use pressure spray guns at work. Sure the clean up is a bit of a hassle (though honestly, I kind of enjoy cleaning my gun). The other big benefit other than the ones you've mentioned is that the gun itself is lighter since the tank is detached, which when you have to paint all day, is much nicer for the ol' arm!
The 1.8 mm tip on the siphon gun is better used for Lacquer, Polyurethane and oil based finish paint.
This is The Best video on various types of spray guns. Thank you.
Thank you for providing us with this information.
Good video, clear explanation! Thank you.
Where the pressure pot really shows it's versatility is that you can tilt the nozzle in any direction whereas the siphon and gravity feed guns limit the nozzle angle. Gravity feed works well until you are spraying upwards and the paint can flow away from the port. Siphon feed works well pointing up but can pose a problem pointing down when the paint level is low. Pressure fed nozzles can be pointed up, down, and sideways.
I still thin paint for the pressure pot because straining a thick paint through a mesh can take a long time.
A flexi pipe on the gravity feed system is a hack for spraying overhead, but two hands are required for holding the pot and gun.
@@the_famous_reply_guy, I had ideas about that.
The siphon spray gun can put out more material than shown the tip used in this video is a 1.8 which is a bit small when it comes to siphoning mateiral. As paint gets highly viscous like above a latex consistency you typically have to thin a bit more to get a good amount of material or use a larger tip.
Not certain about the points made but ,if anyone else wants to uncover car spray painting tips try Sovallo Auto Painting Fixer (just google it ) ? Ive heard some awesome things about it and my work buddy got cool results with it.
which is much better?
Very helpful, thank you very much.
This guy knows his products and paint guns for sure
Great explanation of the 3 types!
Thanks for the video.
Will the gravity HVLP will work painting trailer with rust-oleum oil based. Gloss black
i usually use a 2.5 or 2.8 mm tip for thicher materials on my gravity gun eliminating 30 percent thinner
thank you so much. huge help
Excellent data share! Thank you.
Very useful information. Thanks for sharing
Kun Huang glad it was helpful!
Which one of these has the least overspray?
Great video, thanks
Hi can we use it for house paint
Does a gravity feed gun cup can leak? Or can a siphon feed cup can leak?
thanks for this information
I was painting a bicycle frame and dound out gravity fed is not way to go .gotta save up to get a compressor to use the binks
thanks for this video brave man
I'm about to Plastidip my man's car. With as thick as the material is what type of spray gun do you suggest? I've only ever used basic automotive paint. This will be a first for me.
I have a boat (the entire boat, hull floor, sides) and boat trailer (top and bottom) to paint. My first time using a gun. Would you recommend siphon or hvlp ?
I may go airless with a fine finish tip depends on the paints you choose any paints chosen yet

Thanks for the demo. I just had a 700 square foot wooden deck installed on the back of my house. In about a month it will be time for water seal. Which of the three spray gun methods do you recommend for water seal/staining a deck? Thanks for your time
We like LVMP for wood finishes but generally a wood deck will often be done with an airless
Brush is the answer not spray
@@arturo4700 *I vote hudson sprayer and back roll....wonder what he did...?
Instead of cleaning the pressure feed pot, can I just put the whole can of paint inside? Will the pressure itself spill out the paint into the pot?
They aren't available in HVLP?
Great vid! Very (very) far from Pittsburgh, so can't repay you with our custom, but thanks anyway!!
Clear and concise video. I bought a dual head syphon gun for spraying PU foam (A+B 1:1) the material looks thinner than 'brush on' paint, is it HVLP or LVLP ? Also can't decide on the size, type of compressor.
Most plural guns are conventional tho would need the model to confirm you usually want 20 cfm or more for volume
@@PittsburghSprayEquipmentCo Thx for reply. The gun; Power Aero Nova CS-10 HVLP by Ntools. it’s reviewed here;th-cam.com/video/3Zsa8CA3ui8/w-d-xo.html. It’s supplied with 1.4 nossles. I’ve never done any spray/compressor painting before . The material is in 2x2.5L containers so I’ll have to do some ‘adapting’ to make two syphon take up containers. Thx
@@PittsburghSprayEquipmentCo What do you think? (above) what do you think about two smaller pressure pots?
@@stevesculptor1 plural you usually use 2 piston pumps but could try the pressure pots mix ratio will have limited control
@@PittsburghSprayEquipmentCo I'm going with two adapted pots syphon take up. You say 20 f/pm where I am that is 550 L/pm That's quite big but if it's what you say OK. Thx
Where i can bay this shop .i am life in hongkong .
how much ???
Whats the diffrence between airbrush and spray gun if you don't mind
An air brush is for small detail work while a spray gun is for painting products
Thanks for your soon respond and great video .
QUESTION; 3:33 do you think if the suction tube in the tank is longer then it needs more pressure to suck the paint up?
Hi sorry we didn't see this question typically it shouldn't need much more pressure with a long tube but if the tube is to long it can become blocked because its touching the bottom of the pressure pot
How about a video on tip, needle sizes
we can eventually do that what would you be interested in ? A video that would cover general tips on finding the right tip size for say a standard spray gun and/ or an airless (this may be two videos)
Yea i would agree
Did you end up making the tip vid?
can u use siphon with the paint pot? if you unscrew the pot and connect hoses
AFFLICTION08011 hi if you want to use a siphon cup you would have to choose a spray gun air cap that is siphon feed and change the fluid line to a suction cup so yes it is possible but you need a siphon air cap and separate cup to siphon out of
Pittsburgh Spray Equipment Co may have confused us... i want to use a paint pot for upholstery glue... i bought a siphon gun. its sprays like a hose. even when i unscrew air and fluid pressure on pot. wondering if its my gun or if the thinner im test shooting too thin? wondering if i need a hvlp gun or maby just guidance
Ww2 they used bottom feed and they used on helmets and vehicles to
You're videos are so good! I've learnt alot quickly about the variety of spray guns, and their pros and cons.
There's something I am a bit confused about though. Could you please provide an explanation of what exactly DEFINES an HVLP, say, from a conventional sprayer/LVLP/LVMP. At the moment they're kinda merging into one, and I think a definition of how they work would help explain what makes them different. I realise you touch on it in your videos but you don't really provide a detailed definition of their physical differendes that make them unique?

What would be considered "Airless"?
Airless uses high pressure against a tip to break material up and is what is most commonly used by residential and commercial contractors for painting . In general air spray guns give a finer finish than airless spray guns
Pittsburgh Spray Equipment Co Let me see if I understand this somewhat. I have a 5 HP 20 gal Craftsman air compressor and I can't remember the CFM rating but I'm sure it's not very high. My understanding is that you need a decent size 2 stage compressor to use a HVLP spray gun effectively. At least if your painting larger things like cars etc. I don't paint things that large, I would only be doing things around the house like a go kart frame, mini bike frame and a long locker room style metal bench for now anyway. Would a siphon feed spray gun be more suitable for my needs or will an HVLP gun work? What about just a gravity feed gun that's not HVLP? I'm a little confused about what would better suit my air compressor for now.....A bigger compressor maybe down the road but not in the budget right now and also don't really have the room for a bigger compressor at the moment.....
Jeff Stone you will be able to spray for a short amount of time most gravity guns are hvlp conventional will suit you better for a small compressor a siphon feed is limited with thick materials if a pressure pot is available it would give you more versatility
Pittsburgh Spray Equipment Co Thanks for the info, I've recently learned about LVLP spray guns and am considering those, they also sound like they would be more compatible with a smaller compressor....
Yes LVMP spray guns will use about 11 - 15 CFM and tend to break paint up a bit more effectively
I'm sorry but you're wrong about siphon fed guns. I used a Binks #7 for years and it sprayed as well, if not better than any gravity fed gun I used. I'll take a HVLP siphon fed gun anytime over a a gravity fed one. As a matter of fact the last gun I purchased was a Devilbiss Finishline Siphon fed and it is fantastic.
Hi Dan conventional siphon do spray like a gravity the 7 would be conventional the flg siphon setup is a conventional cap to the flg has both hvlp and conventional caps. Hvlp itself tends to not make great siphon but can be done
This guy reminds me of Matthew Lillard., you know from scooby doo and other stuff...
I'm Indian man
thanks
I wanna buy gravity for my car but I wanna make sure I can spray latex. What's the issue with diluting latex paint - I don't get it? You say the atomization is good, so why not spray latex with gravity, it's faster, more control ...
You have to thin it alot. Thats the problem this guns are made for latex but you could use it for it. But requires extra procedures. Even on the box it says not for latex painting
@@miguelledezma1394 I found a gun QualCom (HomeSteadFinishing, they are rebranded Asturos - good Ita company) and the seller has a painting pack which includes a 2.5mm tip. It has worked well - esp for acrylic based paints from Benjamin (Stix primer, Advance).
?
I wish turbine units had the gravity option.
Hi there are gravity fed turbine options like the Fuji t75 or maximum elite by titan they are both gravity fed
That stuff u used is bad for your cooling system.
So you explain the most basic mode of operation of the different paint spraying devices. I don't know why you completely left out the airless. Since that's probably the most common method for applying paint by the DIYer today. An explanation of the finish left by the different devices would be nice. This video just doesn't have enough information for me. GOD bless you and you reading and watching!
Hi we cover the difference between airless and spray guns here th-cam.com/video/1_3fkZi5xxk/w-d-xo.html
That was so funny
We could appreciate videos being more detailed, longer to have more of your experience, knowledge! Usualy painting videos (or other ) are more like to be just to show everybody your cool new equipment and stylish pants, not this useful info for knowledge - seekers :)
