Small portable air compressor


For an impact wrench, the air capacity of a compressor isn’t very important.


Even if you find a compressor with an impressive specification, you may try to evaluate its service life. Compressors work under lot of stress, so the design and quality of materials are crucial for its long trouble free service.

This means buying a compressor with a well known brand name is pretty much the way to go when you want to run it for a long time. Indeed, you’ll reasonably save money and your time since you can rely on it instead of having to often maintain or repair or even replace your tool.


The compressor is a real helper when it can be easily moved where it is needed for a job. Since there’s only a limited amount of line associated with your tool, chances are you’re going to have to reposition your compressor at least once in a while.

For most people unless you have a shop you will tend to want something with a smaller capacity to keep the weight down.

Wheels and handles are pretty much essential to making sure that you’re able to get things where they need to go.


How much you want to spend on your compressor depends largely on the way you are going to use it. It’s always worth to spend some more dollars, when you’re going to work with the compressor nearly every day.

On the other hand, if you have only weekends for this work you can save a little bit money with a lower price model.


We hope this review helped you make up your mind, what compressor to look for. It can be frustrating when you’re looking for that perfect tool but with a little bit of thought you can make sure that you have exactly what you need.
