If painting a larger job, most of these guns can also be used with a paint tank or remote canister. In order to work properly, the gun must be set in siphon-feed mode to prevent pressure from entering the fluid hose from the wrong direction.
Because these HVLP spray gun are designed to work in a variety of set-ups, they spray well in each function, but not excellent. If a high-quality furniture or automotive finish is desired, it’s best to stick with a gun specifically designed for siphon, gravity or pressure-feed.
In a pressure-feed system, air is used to pressurize the material container, forcing fluid to the tip of the air spray gun, where it’s atomized by air passing through the air cap. Pressure-feed guns can be set up with an attached 1 qt. canister or by using a remote canister. Remote canisters can range from 2 quarts to over 10 gallons. With a remote canister, or pressure pot, the container is pressurized and material flows through a hose to the fluid inlet on the gun. A separate hose provides the necessary air for atomization.
