1. Porter Cable PXCMF220VW – Best For An Affordable Budget

Porter Cable PXCMF220VWEditor Rating:

Porter Cable’s popularity is beyond question. When shopping for an air compressor, undoubtedly your eyes will land on this flashy and simple item first before everything else.
If you are in search for a powerful yet compact tool, Porter Cable PXCMF220VW and its 20-gallon steel tank will certainly do for you.

The gauge equipped can measure the pressure level of the air stored within its tank, which will be more than helpful in showing you how long it will be until the compressor is drained. The device’s capacity is 1.5 HP, a little bit higher than some models from the same product line.

Most of the time, motors of the induction type tend to last longer than those from the universal one. How come? Less intensity required per horsepower can result in just a limited amount of heat produced. This is the primary reason why this machine can retain its good condition for long.

As the manufacturers once said, the model’s pump can run over and over without stopping. However, if you plan to keep the machine functioning properly all the time, it is best to let the average duty cycle stay at just about 50% -75%. Keep it in mind that it would be a bad idea if the machine’s working period exceeds 45 minutes under any circumstances

The maximum pressure of this 120V machine is somewhere in the vicinity of 150 PSI. At 90 PSI, The air distribution would be 4.0 SCFM. PXCMF220VW comes with a range of punches which require 0-5 SCFM to work with compact-air tools, and 120 PSIG is the cutting compression. Meanwhile, so that the user has total control over the cycle of the compressor, the manufacturer has decided to add an automatic pressure switch. Quite thoughtful of them!

  • Does not require daily maintenance
  • CSA certified

How To Choose The Best 20-gallon Air Compressor?

So, if choosing the best 20-gallon air compressor is quite difficult for you, have a look at our buyers’ guides below

Define the Main Functions You Need

Define the Main Functions You NeedFirstly, choose the right-sized compressor for your area and identify the level of mobility you need. A 20-gallon air compressor occupies an average range so that you can find models built for both.

If you need an air compressor for your car jobs in garage, look for a design that mostly suites for installation instead of a high-end model on big wheels and a dependable vehicle. If you want to move it around, a lighter with bigger wheels and a more solid carriage is a big deal.


The engine is an essential component of every air compressor. Depending on how quickly your tank is depleted, your engine can get pretty much used. Find an air compressor combined with real compressors with high-quality motors.

Minimal maintenance and repair also should be considered, such as taking a motor connected to the compressor via a belt. Be aware of any fluid requirements your engine will need and how much it will cost to fix if it is broken.


NoiseAs you know, the air compressor is not quiet equipment. It is designed to run regularly during operation to refill your tank. Gasoline motors might not smoother than electric engines.

The place you want to use it will also affect a lot. For the tasks at the garden and you need to move your air compressor around, stay away from a bulky air compressor as it will make a louder noise than a compact one. You should also note that the noise will increase if you operate it in an enclosed workshop or garage.


Are you considering some similar models? Or if the budget is one of the things you are worried about, then the cost becomes an essential factor in getting the right air compressor for your workplace. Do not pay too much attention to the brand; if there are two models with the same functions and capacity, get a cheaper one. But have a look at its durability also.
