A spray gun is an essential tool for applying paint finishes regularly to furnishings, and there is a wide selection of spray guns to choose from on the market. Understanding what type of spray gun will work best for your application takes a lot of guess work out of the buying one. Read these steps before you purchase a spray gun.
1. Consider how much spraying you intend to do. Many Industrial spray jobs are done with air-assisted airless spray systems, which are more expensive but also fast and efficient. For light to medium spray work, you can choose a less expensive system like a turbine HVLP (high-volume, low-pressure) or a compressor HVLP.
2. Take into account the tools you currently have in your workshop. If you already have an air compressor or have other tools that require a compressor to operate, buy a compressor HVLP gun. Make sure your compressor can produce enough psi (or pounds of air per square inch) to power an HVLP gun. Check the spray gun and compressor specifications to determine a suitable match.
3. If you don’t have an air compressor or intend buying one you have the option of purchasing a turbine HVLP system. Select a three- to five-stage turbine with at least a 6 psi capacity if you intend to spray clear finishes.
4. Establish the type of cup you want for your spray gun. The cup supplies the gun with finish and comes in three main types: remote pressure-fed, gravity-fed and pressurised siphon-fed. Select a remote pressure-fed gun if you do a lot of spraying and want a large container to hold your finish. Choose a pressurised siphon-fed if you only intend to do minimal spraying and have a turbine HVLP. Select a gravity-fed cup if you do small amounts of spraying and have a compressor HVLP.
