HVLP Sprayer Options | Cups vs Pressure Pot

What happens here

The video discusses the efficiency of material usage. For small amounts of expensive material, a gravity feed cup is advantageous as it allows for nearly all the material to be sprayed out. In contrast, bottom-cup (siphon) systems will always leave a residue of material at the bottom because the pick-up tube cannot reach every last drop, especially when it's no longer immersed. However, a gravity cup prevents spraying upside down without material going into the air tube unless a specialized bag system (like 3M PPS) is used.

Tools and materials

  • Gravity Feed Spray Gun
  • Remote Pot System (e.g
  • 3M PPS)
  • Siphon Feed Spray Gun

pull pull it up with the gravity and that's one of the nice things is you can just put a little bit of M Paint in here just to do a small job and be able to spray it out could you spray upside down uh with the gravity cup not very well and that I mean so to some extent we get a good seal on the gasket here so you can tilt them to a side in many cases you would I ever want to go upside down no because I'm now going to have the material going back into my air tube right the only way you could go upside down is if you wanted to introduce a a remote um or a bag system for the gun which would be similar to like the 3M PPS and then you eliminate this uh contact with the air and the paint together and then we're able to use that to be able to tilt the gun in any direction we want but as a traditional cup both the bottom and the Top Cups uh do seal pretty good so you can tilt them to an angle but you wouldn't ever want to put it upside down I think uh you know I've been spraying you know with a siphon cup uh you know for quite a while now I think I I just personally prefer it because I think the gravity cup just gets in the way of my view a lot it also has a lot to do with um the types of things that you're finishing too so if I'm just going to spray a tabletop and I
