What are the advantages of using a gravity feed spray gun?

Gravity feed spray guns offer several benefits. They typically require less air pressure than siphon feed guns, which can result in less overspray and better material transfer efficiency. The gravity design also allows for more complete use of the paint in the cup, as it feeds directly into the gun. Many find them easier to clean as well, since the fluid path is shorter and simpler. Brands like DeVilbiss offer gravity feed cups in various sizes to suit different project needs.

What size gravity feed cup should I choose for my spray gun?

The ideal cup size depends on the size and type of project. Smaller cups (8oz - 20oz) are well-suited for touch-ups or small parts, as they keep the gun lighter and more maneuverable. Larger cups (20oz+) are better for larger surfaces like car panels or furniture, reducing the need for frequent refills. Consider the material you're spraying as well; thicker materials might benefit from a larger cup to avoid constant refilling. For example, Sharpe Manufacturing Co offers a 20oz aluminum gravity cup suitable for a variety of coatings.

Are gravity feed cups interchangeable between different spray gun brands?

While some gravity feed cups may appear similar, they are generally not directly interchangeable between different brands due to variations in thread size, cup angle, and sealing mechanisms. Attempting to use an incompatible cup can lead to leaks or improper gun function. Always use a cup specifically designed for your spray gun model or a universal adapter if available. DeVilbiss, for example, offers specific gravity cup lids designed for their cups.

What is the purpose of the fluid strainer in a gravity feed spray gun cup?

The fluid strainer, or paint filter, prevents contaminants and dried paint particles from entering the spray gun and causing clogs or imperfections in the finish. It's a crucial component for achieving a smooth, professional-quality spray. Regular replacement of the filter ensures optimal paint flow and prevents damage to the gun's internal components. DeVilbiss offers fluid strainer kits specifically designed for their gravity feed cups.

What material is best for a gravity feed spray gun cup: aluminum or plastic?

Both aluminum and plastic gravity feed cups have their advantages. Aluminum cups are typically more durable and resistant to solvents, making them suitable for a wider range of materials. Plastic cups are often lighter and easier to clean, and are a good option for water-based paints. Consider the types of coatings you'll be using most frequently when making your choice. Some manufacturers, like Binks, offer durable plastic lids for their gravity cups.

How do I properly clean a gravity feed spray gun cup?

Proper cleaning is essential for maintaining your gravity feed cup and ensuring optimal spray gun performance. Immediately after use, empty any remaining paint and rinse the cup with the appropriate solvent for the coating you used. Use a brush to scrub away any residue, paying attention to the threads and corners. Ensure the cup is completely dry before storing it. Always consult the paint manufacturer's recommendations for the appropriate cleaning solvent.

What should I do if my gravity feed spray gun cup is leaking?

A leaking gravity feed cup can be caused by several factors. First, check that the cup is securely tightened to the gun. Inspect the cup lid and gasket for any damage or wear, and replace if necessary. Ensure that the correct lid is being used for the cup. If the threads on the cup or gun are damaged, the cup may need to be replaced. Always refer to the spray gun manufacturer's instructions for troubleshooting and repair guidance.

Can I use disposable liners with my gravity feed spray gun cup?

Yes, disposable liners are available for many gravity feed cups. These liners offer a convenient way to reduce cleanup time and minimize solvent use. They also help prevent contamination when switching between different types of coatings. Ensure that the liners are specifically designed for your cup size and shape for a proper fit. Check with the spray gun or cup manufacturer for compatible liner options.
