Below: how each system works, the gear in this guide, and how to pick the right one for your next paint job.
Pressure pot vs airless paint sprayer: how each one works
A pressure pot system starts with a sealed pot that holds the paint. Shop air pressurizes the pot and pushes paint through a hose to the spray gun, and the gun adds air to atomize the paint into a fine mist. The Ouya R77P lists three adjustable valve knobs for precise paint application, an operating pressure of 58 to 94 PSI (4.0-6.48 bar), a spray distance of 250mm (9.84 inch) and a pattern width of 350mm (13.78 inch). The STARY gun lists three adjustable valve knobs, an operating pressure of 3.0 to 3.5 bar (43 to 50 Psi), a spray distance of 150-200mm (6-8 inches), a pattern width of 135mm (5.3 inch) and an average air consumption of 3.0 cfm. A pressure pot suits work where the finish matters more than raw speed: cabinet doors, trim, panels and detail work.
An airless sprayer works in a different way. A pump pressurizes the paint itself and forces it through a small tip at high pressure, so no compressor feeds the gun. The Graco Magnum X5 lists 3000 PSI with adjustable pressure control for interior and exterior work, and the InoKraft NEO lists 3000 PSI with a flow rate of 0.26 GPM. The InoKraft title also states thinning-free spraying for latex paint and stain, and a 10-min cleanup. An airless sprayer suits large flat areas where coverage speed is the priority: walls, fences, ceilings and big panels.
| Point | Pressure pot | Airless sprayer |
|---|---|---|
| How paint moves | Shop air pressurizes a sealed pot and feeds a spray gun | A pump pushes paint at high pressure through the tip |
| Finish | Fine atomization with adjustable valves for control | Fast, heavy coverage; the tip sets the pattern |
| Speed | Steady pace for detail and smaller work | High output for walls, fences and large areas |
| Air supply | Needs a compressor and shop air | No compressor at the gun; the pump does the work |
| Cleanup | Clean the gun, hose and pot after the job | Flush the pump, hose and tip after the job |

The listings below are ranked by Shop Score, with the full-data pressure-feed guns ahead of the title-only airless sprayers. Each one is described from what its listing states, and nothing more.
Ouya R77P pressure-feed spray gun
The Ouya R77P lists a 2.0mm nozzle, an operating pressure of 58 to 94 PSI (4.0-6.48 bar), a spray distance of 250mm (9.84 inch) and a pattern width of 350mm (13.78 inch). The listing states a one-piece all steel gun body with three-layer nickel-chromium plating, a stainless steel nozzle and a solid brass cap, plus three adjustable valve knobs for precise paint application. It mates with a pressure tank or a diaphragm pump, and the set includes a 1/4 inch US Quick Connector, a cleaning brush and a multi-size wrench. The listing gives dimensions of 5.5 inches x 0.8 inches x 6.2 inches. The wide pattern suits large area painting work.
STARY pressure-feed spray gun
The STARY gun lists a 2.5mm nozzle in its title and in the spec table, while the bullet text states a 1.3mm nozzle size: the listing disagrees with itself on nozzle size, so confirm the nozzle before ordering. It lists an operating pressure of 3.0 to 3.5 bar (43 to 50 Psi), a spray distance of 150-200mm (6-8 inches), a pattern width of 135mm (5.3 inch) and an average air consumption of 3.0 cfm. The listing states a one-piece all steel gun body with three-layer nickel-chromium plating, a stainless steel nozzle, a solid brass cap and three adjustable valve knobs. It works with a mating pressure tank or diaphragm pump, and it comes with a 1/4 inch US Quick Connector, a cleaning brush and a multi-size wrench. The listing gives a weight of 1.14 pounds and dimensions of 6.62 inches x 0.71 inches x 6.22 inches. The narrower pattern suits smaller panels and touch-up work.
InoKraft NEO airless paint sprayer kit
The InoKraft NEO is a title-only listing, so the facts below are all the listing states: 3000 PSI, 0.26 GPM, lightweight, thinning-free spraying for latex paint and stain, aimed at DIY beginner house painting for interior walls and cabinets, with a 10-min cleanup. No dimensions, no weight, no hose or tip details are stated in the listing data. The stated flow rate and the thinning-free claim are its concrete points.
Graco Magnum X5 airless paint sprayer
The Graco Magnum X5 is also a title-only listing. The title states Model X5, 3000 PSI, adjustable pressure control, and interior and exterior use. No further details are stated in the listing data: no flow rate, no dimensions, no weight and no cleanup details. The adjustable pressure control is the one stated feature that sets it apart.
How to choose between a pressure pot and an airless sprayer
Start with the finish you need. When a smooth, controlled coat matters most, a pressure pot gun with adjustable valves gives you that control, and the Ouya and STARY guns both list three adjustable valve knobs. When the job is mostly square footage, an airless sprayer moves faster, and the Graco and InoKraft listings both state 3000 PSI. Check your air supply before choosing a pressure pot gun: the STARY listing states an average air consumption of 3.0 cfm, and the Ouya listing states an operating pressure of 58 to 94 PSI, so your compressor has to cover the gun you pick. An airless sprayer needs no compressor at the gun. For cleanup, the InoKraft title states a 10-min cleanup; for any sprayer, follow the manual and the paint maker’s instructions, and clean the gun or pump, hose and tip before the paint sets. Our picks for the best pressure pot for paint and the best airless paint sprayer compare real models side by side.

FAQ: garage tools
What is a paint pressure pot?
A paint pressure pot is a sealed pot that holds paint under air pressure and feeds it through a hose to a spray gun. Shop air pressurizes the pot, and the gun adds air to atomize the paint. The Ouya and STARY listings both state that their guns mate with a pressure tank or a diaphragm pump.
How do you use a pressure pot paint sprayer?
Fill the pot, seal the lid, connect the air line, and set the pressure to the listing for your gun: the Ouya R77P lists 58 to 94 PSI, and the STARY gun lists 3.0 to 3.5 bar (43 to 50 Psi). Hold the gun at the listed spray distance, 250mm for the Ouya and 150-200mm for the STARY, then clean the gun, hose and pot after the job. Follow your sprayer’s manual and the paint maker’s instructions.
What pressure does a pressure pot spray gun need?
It depends on the gun. The Ouya R77P lists an operating pressure of 58 to 94 PSI (4.0-6.48 bar), and the STARY gun lists 3.0 to 3.5 bar (43 to 50 Psi). Check the listing for your gun and set your regulator to match.
Can an airless sprayer spray latex paint without thinning?
The InoKraft NEO title states thinning-free spraying for latex paint and stain. That claim covers the InoKraft listing only: check the listing for any other sprayer before assuming it handles unthinned latex.
Pressure pot vs airless paint sprayer: which one fits cabinet doors?
A pressure pot gun fits cabinet doors well: the Ouya and STARY guns list three adjustable valve knobs and fine atomization for a smooth, controlled coat. An airless sprayer covers large flat areas faster, so it fits walls and fences better than small detailed work. Pick the pressure pot when the finish is the priority, and the airless sprayer when speed over a large area is the priority.
