You may find some twin-stack designs in a wheelbarrow configuration as well. Wheelbarrow – Some larger compressors have a larger pontoon style, but due to the weight of the tank and the other compressor components (such as the motor), they come with wheels and handles to help with moving them around the shop. This style is used to increase capacity in a compact space on portable compressors. Twin Stack – Same as a pontoon tank, but there are two of them as the name implies. They are mounted horizontally and are also used in compressors with smaller capacities. It has a horizontal cylinder that looks similar to the pontoons on a pontoon boat. Pontoon – This style is another common portable compressor design. The compact design helps with portability in a smaller package. Pancake – Pancake tanks are typically found on smaller (3 to 6 gallon) portable compressors. There are five general types of tanks that you may find: In contrast, using a small finish nailer to do some trim work in your basement would probably suffice with, for example, a small three-gallon tank. That requires more airflow, therefore a bigger tank can store a larger volume of air ( industrial compressors can have air tanks as big as 60 gallons or more). If you are using a tool that has a large air capacity, then a smaller tank size will not give you enough reserve air at the right CFM and PSI to keep the tool functioning as it should.Īnother way to look at it is to consider whether or not your tools will be continuous duty. Tank size is critical in order to keep the air supply at the right levels when you are operating a tool (or multiple tools, if you are in an environment where people are using more than one air tool at a time with a single compressed air source).Įssentially all of the air to power your tools comes from what is stored in the tank. This is much better for indoor uses where you may have to have conversations with others in the room. Newer designs take this into account in order to reduce the noise levels. Traditionally air compressors tend to be fairly loud. This is more a function of the overall design of the air compressor instead of relating to the size and capacity needed. Gas compressors are the perfect solution for outside work where there are no readily available electrical outlets.īesides…running a gas engine in an enclosed area is an extremely dangerous thing to do! The engine will emit dangerous combustion fumes that can be deadly (such as carbon dioxide). Indoor applications are almost exclusively handled with electric compressors. What kind of power source do you have?ĭepending on where you plan on using the compressor, the power source that you will have available in a particular environment is critical. They have the ability to run for long stretches without stopping. Continuous duty compressor pumps require a little bit of oil to keep their pistons moving freely. These oil-free compressors are designed to take frequent breaks to cool down. This means that they do not need oil added to them. Using a sandblaster means a constant air supply is required while the tool is in use, therefore needing more air capacity for proper operation. The nail gun is used in short bursts where the compressor can have time to replenish the air supply. This simply means “will your tool be compressing 100% of the time”.Ī good way to look at it is a nail gun vs. Smaller jobs inside your home would benefit from a small portable unit, while the more demanding needs of a shop would need a larger compressor that can manage several types of tools and has the capacity for tasks that may require more torque and power from your tools. Where Will Your Use It?Īre you looking to do some handyman work around the house, or are you setting up your own shop in your garage or pole barn? This allows multiple employees to operate multiple air tools without a drop in air supply. Generally a 30-gallon compressor will produce the power needed to run an impact wrench.īody shops and large cabinet shops generally run larger compressors that are 60 or 80 gallon in size. Mechanics tend to need a larger compressor. If you are just doing construction projects around the house, a portable pancake compressor that can produce 4 CFM can do everything you need. Here are other main things that you need to think about when looking for the air compressor that will be the best choice for your needs The CFM and PSI requirements for the air tools you plan to use are only one part of the equation. However, here are some of the well-known air compressor size requirements based on your tool type. You can check your tool for that exact amount. Most tools will have a CFM and PSI requirement. Air Compressor Size Chart By Tool (PSI/CFM) Generally this will be an 80-gallon compressor. You need 20 CFM of airflow to power sandblasters.
