There are a lot of different kinds of air compressors out there, so it can be tough to know which one is the best for impact wrenches. You'll want to make sure that the compressor you choose is powerful enough to run the impact wrench, and that it has a good tank size so that it can store enough air to keep the tool running for a long time. You'll also want to make sure that the compressor is easy to use and maintain, so that you don't have to spend a lot of time fiddling with it. One option that meets all of these criteria is the Makita MAC2400 air compressor. This compressor is powerful enough to run most impact wrenches, and it has a large 4.2 gallon tank so that it can store plenty of air. It's also easy to use, with an automatic shut-off feature that kicks in when the tank is full, and a drain valve that makes it easy to empty the tank when you're finished using it. If you're looking for an air compressor that can handle your impact wrench needs, the Makita MAC2400 is a great option to consider.
