​If you are looking into buying a replacement or your very first air compressor, check out Porter-Cable CMB15 Fully Shrouded Compressor the subject of this review.

​What are the important aspects of the Porter-Cable CMB15 Fully Shrouded Compressor?


The Porter Cable CMB15 is definitely under the portable air compressors because it is designed to be moved around efficiently with its built in handle. The 1.5 tank gallon is fully shrouded so it makes it easier to carry, despite the weight.

The exact weight of this air compressor is 20 pounds, so you’ll definitely have no trouble moving it around the house or outdoors, wherever you plan to use it.

Power Source:

This machine is powered by electricity. Check your home’s outlet to see if it can support or matches with the machine’s 120 volts.

Otherwise, you might need to use an electric transformer. Electric air compressors such as the Porter Cable may be powerful enough to use tools for household jobs but it might not be enough for big tools for extensive jobs.

If you are looking at doing heavy tasks, which involves the use of multiple tools, or you need to power them up for extensive periods, you might need an air compressor powered by gas. These are more powerful and can withstand long usage.

There are downsides though as these may be a bit costly and difficult to maintain. Not to mention the emissions so you can’t use it inside your home.

Performance Rating:

The capability of an air compressor to support pneumatic tools is measured in terms of Standard Cubic Feet per Minute, or SCFM. Air tools also come with SCFM so if you want to know the right choice for air compressor, you need to check the tools that you’re planning to use with it and compare it with the SCFM of the compressor.

The Porter Cable has an SCFM of 2.0. This measurement is too low if you’re planning to use big tools, or if you’re going to use multiple small tools at the same time. In general, smaller tools usually require between 0-5 SCFM, while larger tools can require 10 or more SCFM.

As mentioned, the SCFM of multiple tools that you plan to use must be added to compare it with the air compressor’s SCFM, to know if it would work.

Tank Size:

The tank size determines how long you’ll be able to use the air compressor for. Porter Cable has a 1.5-gallon tank with 90 psi allowing for quick compressor recovery time. It also has a 150-psi max tank pressure that allows storage of more air for longer tool runtimes.

Porter Cable’s relatively small tank only allows for use of small tools. It also can’t promise continuous tools because the average requirement for using pneumatic tools should be around the 2-6 gallons range.

Additional Features:

This air compressor has a durable oil-free pump for long life and no maintenance. It has a low noise motor at 79 dBA, so you can use it inside your home without disrupting anyone.

The package comes with a 25-Feet coil hose and an 8 pc accessory kit that facilitate a number of inflation tasks. For added peace of mind, your machine comes with a one-year warranty on compressor components.

​What other things should you know about the Porter-Cable CMB15 Fully Shrouded Compressor?

This product is a good price for the sturdy and reliable machine you’ll get. It doesn’t need any assembly and can be used right out of the box.

Few people however noted that the air hose is quite cheaply made but poses no problem as any hose from a hardware store can easily replace it. The airflow rate and usage lasts enough for you to complete a couple of jobs before you take a break for the compressor to refill the tank.

It’s also lightweight; you can just grab it from the storage room with ease, plug it, and use it. Moving it around the house is also easy because of the built in handle atop. Only con for this product is the fact that it’s built for light usage with small pneumatic tools.

For its low price compared to other air compressors of this range and size, the Porter Cable CMB15 delivers a punch. It can power up a number of pneumatic tools and fill tires and other flotation devices fairly quick.

It’s also very quiet while operational, which means there’s no problem using it inside the house. The sturdy materials used for the parts make it a reliable home-level compressor that you can rely on.

​​​Before buying this air compressor, make sure to check all the air tools you’re planning to use it with because this compressor can only power a number of small pneumatic tools. When you say small tools, think brad nailer or airbrush. This is definitely not for the hardcore builders and DIY enthusiast.

It’s good to have around the home for minor builds and repairs, as well as for filling air, but if you expect to use it more than that, you’ll be disappointed.

​The Verdict

​The Porter Cable CMB15 may be considered as the best and durable air compressor there is if it is just right to suit your needs and preferences. It does no problem with powering up small tools and filling tires but you’ll run into trouble if you get more ambitious than that.

This is because the machine is designed to take only a little bit of work and is considered consumer-grade. If you need more power, look elsewhere.
