For some comparison, this is approximately the same sound output as a food blender. Most modern electric compressors are in the high 60’s to low 80’s decibel range. Large engines will usually come with a higher cost and increased weight making the compressor less portable.Īnother issue when selecting the motor size is what is the accompanying noise produced? Manufacturers will provide the level of noise as measured in decibels (dB). However the more powerful the motor, the faster it can fill the tank and keep up with high-demand air tools. Note that the motor power isn’t directly related to the performance of the air tools. The motor size is typically measured in horsepower. Pancake compressors offer a great compromise between usability and portability with a compact, efficient design. Horizontal tanks offer the ability to be moved around with a set of wheels on one end but tend to take up more usable space. Vertical tanks are great if there is an appropriate location in the garage or shop as it takes up less floor space, as long as it rarely needs to be moved.

If you plan on constantly moving it around and your air tool demands are not excessive, go with the lightest, most compact design possible, this will make your life much easier.Ĭommon tank shapes include pancake, vertical and horizontal (also called a hot dog tank). However, if it is very heavy the wheels won’t help when loading into a truck. Some models include wheels which can make it easier to move around the same area. If you plan on just keeping it in the corner of the garage, a larger compressor can provide the flexibility to use a much greater ranger of tools. How will you be most often using the compressor? Hauling it to the job site every day? Always keeping it in the garage? Here are some features to look out for when selecting a model: If you need more reserve air, for example, if you are working away from a power source, you may need a larger tank. This is why the size of the tank is important. When the air in the tank is depleted the motor automatically turns on and replenishes the used air.
