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.

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.
