Things You Need to Know Before Buying 

Compressor Type

There are two main compressor types to choose from single-stage and two-stage air compressors. The choice of either one of these will mainly depend on the intended application. Single-stage air compressors are comparatively small in size, and capacity. 

This makes single-stage compressors suited for simple, light-duty applications like airbrushing. Even with single-stage compressors, you still need to choose the size and capacity that you find appropriate, as discussed below. Two-stage air compressors are suited for garages and manufacturing facilities.

Milwaukee’s two-stage compressors are powerful enough to run multiple pneumatic tools simultaneously. As compared to single-stage models, two-stage air compressors are larger and more expensive. 

Air Compressor Grade 

Compressor Pressure Range and Airflow Based on their capacity and power, air compressors can be classified into three different grades as follows: 

  • Consumer Grade Compressors – These are small, often single-stage compressors that are suited for DIY home applications. They may also be used in small garages to power a single pneumatic tool at a time. 
  • Contractor Grade – These are comparatively larger, but still portable air compressors. Contractor Grade compressors that have larger tanks come with a set of wheels or are mounted on a cart-like vehicle. They may be used to power small tools at a construction site, including roadside repair tools and nail guns. 
  • Commercial Air Compressors – Milwaukee commercial air compressors are really powerful. The Milwaukee 2840-20 M18 FUEL 2-Gallon, for instance, is suited for heavy-duty compressed-air applications. Such compressors are powerful enough to power multiple pneumatic tools simultaneously and feature large storage tanks for uninterrupted operation. 

Compressor Pressure Range and Airflow 

To understand the capacity of your preferred Milwaukee air compressor model, you should consider its pressure range (PSI), and airflow rate (CFM). The right PSI and CFM will depend on the type of tools you will be using the compressor to power. If you intend to be using several air-powered tools with your compressor, it is advisable to get one with a higher CFM value. Consider the type of tools you are currently using and the ones you may need to use in the future. 

Your preferred air compressor must meet the PSI and CFM requirements of each pneumatic tool you will be using. Determine which of the tools requires the highest CFM at the highest PSI. For marginal safety, you should get a compressor that delivers 50% more CFM than the CFM requirements of your tools. 

Power Source 

The leading air compressor models in the industry are powered by either electricity or run on fuel.  While shopping for the right air compressor, these are the two power sources you should consider:

Electric Air Compressors 

Most Milwaukee air compressors run on electricity. Regardless of their size, electric air compressors are more efficient, quarter, and friendlier to the environment. They are the perfect choice for places with a regular supply of electricity. Since they do not have large engines and gasoline tanks, electric compressors are lighter and easier to carry around. However, electric compressors are less powerful as compared to models that run on fossil fuel. Again, larger industrial electric air compressors may also require you to buy a 400V or 3-phase supply transformer. This will add to the buying cost and make the compressor bulky. 

Fuel-Powered Air Compressors 

The more powerful industrial air compressors are powered by either gasoline or diesel. As compared to diesel-powered models, gasoline air compressors are lighter, more affordable, and quieter in operation. Diesel-powered models, on the other hand, produce more horsepower and torque. Diesel-powered air compressors may be costlier to buy but are relatively cheaper to maintain in the long run. All in all, Fuel-Powered compressors are best suited for heavy-duty, outdoor applications. 

Mode of Operation 

With regard to their operations, air compressors use two main mechanisms: rotary screw and piston methods. Most piston air compressors are often used in the automotive service industry. Such models are known to deliver lower air quality and output flow rate. Piston air compressors are also noisier in operation and operate at a higher temperature. As a result, they may be costlier to maintain per given duty cycle. Piston compressors will also consume more power per unit output. For enhanced reliability, durability, energy efficiency and improved air quality, you should get a Milwaukee rotary screw air compressor. 

Final Verdict 

best milwaukee air compressorMilwaukee is a leading manufacturer is an assortment of electric and pneumatic tools. Their range of air compressors is just as efficient, reliable, and durable. Their M12 compact inflators are suited for home applications and inflating tires of all sizes. The M18, 2840-20 model, on the other hand, is ideal for heavy-duty applications. All their models feature a compact, lightweight, and portable design for easy transportation and storage. Regardless of the intended application, Milwaukee air compressors will offer you a reliable, and flexible cordless experience.
