Porter-Cable CMB15 Review

Basics and Specs

The CMB15 has one tank the total capacity of which is 1.5 gallons. It’s entirely shrouded that provides better safety and convenience. Moreover such design makes it easy to transport the unit and combined with its weight of only 20 pounds the compressor becomes significantly portable. In addition to that, it also has a convenient carrying handle that allows moving the unit around as you wish without much effort.

The 0.8HP motor and a single-stage pump can supply 2.0 SCFM at 90 PSI, or 3.0 at 40 PSI. The maximum pressure rate it can deliver is 150 PSI. Being designed specially for the lightweight household tasks, the compressor can help you out with inflating the tires of your car, cleaning, and nailing. It’s also powerful enough to manage some industrial jobs as well. Despite its small size, the compressor provides a decent airflow allowing longer running time and shorter recovery rate. As the model is oil-free, you won’t have to bother much about the maintenance as long as you use it according to the manual’s guidelines.

The compact size of the compressor (16″ X 13″ X 21″) allows storing it practically everywhere as it doesn’t require much space. It doesn’t need high voltage to start running; in fact all you have to do to turn it on is simply plug it into the electrical outlet. It needs standard 120Volts and drawing 10 AMPs while running. The compressor provides proper functioning even if you use extension cord or in cold weather conditions.

The unit comes with 8 accessories kit that makes it ready for instant use. The drain valve and rubber feet reduce the vibration and consequently decrease the level of noise it creates to 79dB. This feature is a great advantage of the product as not all of the more expensive models have the same noise reduction level. This is one of the quietest compressors available at the moment.

Oil-less Pump

The oil-free compressors gain more and more popularity. Such units don’t require careful maintenance and simultaneously they have a long lasting service life. The aluminum body of the compressor adds even more sturdiness to the construction of the unit together with the shrouded design eliminating the risks for users and unintended damage of the compressor’s components.


This is one of the biggest advantages of the model. Its small size and light weight make it perfect for using in small rooms, or transporting it from one location to another. Nevertheless, its compactness doesn’t compromise the performance rate as the compressor provides the strong and continuous airflow able to cope with the various tasks effectively and quickly. Therefore, this model offers almost the same range of features and technical abilities like its more expansive business rivals, but it is way more affordable than its competition.

w256h2561339252558DeleteRedIt’s important to note that it was very hard to come up with any disadvantages of the compressor. The only complaint we managed to find among the reviews from customers was the shrouded design of the compressor. Some people don’t like having the components of the unit concealed as they find it better to observe “what’s going on” inside. Still, this is more a personal preference that doesn’t have anything to do with the particular product’s features or performance rate.
