How does a paint sprayer work?

All paint sprayers function based on the same core principle: they turn fluid paint into numerous atomized, tiny droplets, which are then sprayed onto a surface. With pressure guns, the fluid flows out when pressurized. Gravity-feed guns rely on gravity to cause the paint to flow down.

Why is paint not coming out of my sprayer?

If your paint gun is not spraying paint at all, it’s most likely due to a clog either in the air vent hole or the hose. Clean any dried paint with a toothpick, and use a cleaning solvent to clear any remaining gunk. If you’ve cleaned your paint gun and find that it still isn’t spraying, take a look at the air supply.

How do electric sprayers work?

An airless sprayer works by pumping paint at a very high pressure, up to 3,000 psi, through a hose and out a tiny hole in the spray gun tip. The tip is designed to break up the paint evenly into a fan-shaped spray pattern of tiny droplets.

How big of an air compressor do I need for a HVLP spray gun?

HVLP guns require plenty of air, so you may have to buy a larger compressor. The manufacturer of the gun shown recommends a minimum of a 3-hp compressor with a 20-gallon tank. Although this is an added investment, you can use the compressor to power other tools.

How does a paint sprayer work and how does it work?

Within the compressed air sprayer, air jets direct paint to the air nozzle, which atomizes the paint and propels it onto the surface that you’re painting. The fluid nozzle controls the paint’s delivery, while the needle assembly is what causes the paint to flow.

What kind of pump does a paint sprayer use?

The pump, which powers the process, comes in two basic types: piston and diaphragm. Piston pumps can handle thicker paint, but diaphragms are often less expensive. Piston pumps sit at the spray head of the gun and are powered by the motors hydraulics. First, the piston moves up, creating a vacuum, which draws paint into the chamber.
