Nozzle size decides the material, whatever the badge says
A spray gun is matched to two things: the material and the compressor. Nozzle size does the first — makers publish ranges, broadly finer nozzles for base coats and larger ones for primer and filler — and a gun bought with one nozzle covers one job. Air consumption does the second: HVLP guns move a lot of air at low pressure, and the stated liters per minute have to sit inside what your compressor actually delivers, not its peak figure. LVLP designs exist precisely for smaller compressors. We compare nozzle sizes available, HVLP against LVLP, cup type and capacity, needle and nozzle material, and what comes in the box. Not one of these listings publishes an air consumption figure, which is the specification you would most want.
HVLP · 3 stainless nozzles 1.4, 1.7 and 2.0 mm (0.08 in) · conical air cap · mesh filter
Three stainless nozzles covering base coat through primer, with a mesh filter that keeps dirt out of the fluid passage.
Best for: A first spray gun for a small job, where nozzle flexibility matters more than refinement.
Two guns · nozzles 0.8 mm (0.03 in) and 1.4 mm (0.06 in) · cups 125 ml and larger · sorting case
Two guns rather than one gun with two nozzles: a 0.8 mm (0.03 in) detail gun and a 1.4 mm (0.06 in) panel gun, each with its own cup.
Best for: Spot repairs and small panels, where a full-size gun is too much.
HVLP · 3 copper nozzles 1.4, 1.7 and 2.0 mm (0.08 in) · 360° rotatable · aluminum body
The same three-nozzle format in copper rather than stainless, in an aluminum body — and the nozzles rotate, which lets the fan be turned without moving the cup.
Best for: Someone spraying solvent-based materials who wants fan control.
HVLP set of 3 guns · stainless nozzles · aluminum case · stated low overspray
Three guns in an aluminum case with stainless nozzles — the set that covers primer, base and detail without changing anything.
Best for: Someone equipping for a full repair rather than a single coat.
LVLP · complete set with pressure regulator and oil/water separator · stated high transfer efficiency
An LVLP gun sold as a complete starting kit: regulator, oil and water separator and gun together — the three things a spray job actually needs.
Best for: A first spray setup on a small compressor, where the accessories would otherwise be a second order.

The quality of the nozzle and air cap decides how fine the spray is. That is what separates a smooth finish from orange peel.
An entry-level gun lets you learn the settings on test panels before investing.
A gun asking for three hundred liters a minute spits behind a compressor that delivers two hundred. The stated air consumption is compared with the compressor's delivered flow, not with its label.
Flow matters more than pressure: these guns consume a lot of air continuously. An undersized compressor runs out of breath mid-pass.
Absolutely: moisture in the air causes craters in the paint. A water separator at minimum, a dryer ideally.
Immediately after use, fully stripped, with the solvent for the product used. Paint dried in a fine passage is very hard to remove.
It depends on the product: primer, color and clearcoat do not have the same requirements. The product manufacturer states the suitable range.
Product too thick, insufficient pressure, or too great a distance. All three give the same defect and are corrected differently.
A constant distance, movement parallel to the surface and an even overlap. Consistency of movement does more than the settings.
A cartridge mask suited to solvent vapors, never a simple dust mask, plus ventilation. Some products call for enhanced respiratory protection.
Thick primer wants a wide nozzle, clearcoat a fine one, and a single nozzle does neither well. The stated nozzle sets decide the gun's real versatility.
Air flow matters more than pressure: an undersized compressor degrades the spray mid-pass. Clean immediately and fully stripped — paint dried in a fine passage is irreversible — and solvent vapors call for a cartridge mask, not a dust mask.
A column is opened only if four tools in five publish its value. Otherwise the table would compare what nobody has measured.
