What is a pressure feed spray gun?
More specifically pressure fed spray guns that utilize a pressure tank with dual regulators. A dual regulated pressure tank gives you precise control over pressure of fluid both to the material and to the air that breaks the material up (the atomization air).
What PSI should I run my paint gun at?
10-15 psi when trigger is pulled for base coat is what most say to set your gun at. Personally I spray at about 17 psi when spraying base coat and 20-25 for clear coat using the low volume low low pressure spray guns. The normal scfm that these guns use is 5-7 scfm cubic foot per minute.
How much air pressure does it take for a paint gun to paint a car?
Look for a minimum of 15 psi, with some applications, such as clear coat, better-suited to 20 or 25 psi. Horsepower: For auto painting, a 10hp compressor will typically suffice. However, higher horsepower compressors may operate more efficiently, and can be used for other tasks.
Are gravity fed spray guns better?
Summary. In most cases, a gravity feed paint spray gun is the better choice thanks to its efficient and versatile design. Although HVLP is a requirement in most areas, whether or not you use an HVLP gun, gravity feed offers the advantage over conventional feed because of the lower air pressure requirement.
How much pressure does a HVLP gun need?
HVLP, or High-Volume/Low Pressure, uses a high volume of air (typically between 15-26 CFM) delivered at low pressure (10 PSI or less at the air cap) to atomize paint into a soft, low-velocity pattern of particles. In most cases, less than 10 psi is needed in order to atomize.
How does a pressure feed spray gun work?
Pressure and Siphon-feed guns are the oldest of designs. In pressure guns the fluid is pressurized, allowing it to flow out (these aren’t used much anymore). In siphon guns the movement of the air inside creates a siphon that pulls paint out of the reservoir. The Air Cap is the part that does the real work.
What PSI should I spray clear coat?
When spraying base coat clear coat systems, you want to spray at 26-29 PSI. You measure this PSI by pulling the trigger and letting air flow through the tip of your gun with your dial or digital readout saying 26-29 PSI.
What is the advantage of a gravity feed spray gun?
Gravity feeds require less air pressure to atomise the paint, providing the direct benefits of lower overspray, less paint wastage, and a greater level of control for the painter. Thanks to these advantages, the gravity feed gun typically delivers better finishes.
How can you tell the difference between HVLP and conventional spray guns?
The high pressures of conventional spray guns turn paint into a finely atomized mist, giving you a thinner, finer application. HVLP spray guns produce a thicker coat due to their lower pressure, producing large droplets.
Does a spray gun make a difference?
Deciding between a budget spray gun and professional Spray Gun. The professional spray gun offers greater performance and the potential to finish your work faster. It also offers greater control of your painting. However, you do have the additional initial cost.
Can a pressure feed spray gun be used?
A pressure fed air spray gun can also be used at literally any angle which is not possible with gravity feed or suction feed spray guns because the paint cup on the spray gun will either leak or at extreme angles paint will not enter the spray gun.
What should the pressure be on a base coat gun?
10-15 psi when trigger is pulled for base coat is what most say to set your gun at. Personally I spray at about 17 psi when spraying base coat and 20-25 for clear coat using the low volume low low pressure spray guns. The normal scfm that these guns use is 5-7 scfm cubic foot per minute. Volume of air used at 40 PSI.
Can a spray gun be attached to a pressure pot?
It is generally not possible to achieve these flow levels of fluid using a siphon fed spray gun. An easy check to see if your siphon feed spray gun may work attached to a paint pressure pot or double diaphragm pump is to test the spray gun attached to your pressure tank or pump with water.
Why do you need a suction fed spray gun?
Atomization will occur naturally as air required to feed material to the spray gun will automatically create the atomization you need Wood finishing is a frequent use for suction fed spray guns due to the natural tendency of a suction fed spray gun to create proper atomization because of the guns air requirements to feed material to the gun
