To help make your decision easier, we’re going to share some of the top 4-gallon compressors on the market today. When comparing these models, keep the following things in mind:

  • Tank Style: Does the compressor have a vertical, horizontal or twin-tank design? The design of the tank doesn’t necessarily affect its performance, but it does have an impact on the compressor’s portability. Choose a style that suits your needs best.
  • Air Flow Rate: The air flow rate determines the power and efficiency of the compressor. A higher flow rate generates more power, but may not offer as long of a run time as a model with a lower flow rate.
  • Quality: The quality of the compressor is one of the most important things to consider when comparing models. Obviously, you want a quality compressor, but judging quality can be difficult when you can’t take it for a test drive. One way to judge quality is by the brand’s reputation. Reputable brands put out quality products (typically), so choosing a model from a well-known and respected brand is a great place to start. Also, look at user reviews for the product. If users have great things to say about the compressor, it’s likely a good choice. If the compressor has numerous complaints, it may not be the ideal option.
