What Are Air Compressors?
Air Compressors are mechanical devices used to increase pressure in different compressible fluids or in the air among other gases.
Large Air Compressor is usually used to supply a certain tool or an entire shop with air. The air is used to power air tools, abrasive blast equipment, paint sprayers.
In addition, a large air compressor is used by industrial refrigerants for air conditioning and refrigeration. The Air conditioning system depends on a steady stream of air to propel gas through the pipelines.
Types of Air Compressors
Compressors are divided into centrifugal (or dynamic or kinetic) and positive-displacement types, more often being the latter.
They can range in size from a few gallons to the gigantic machines found in pipeline service. This review will focus on the best 100, 120, and 200-gallon air compressors.
Users of Commercial Air Compressors
Air compressors are vital in many manufacturing processes. Furthermore, it is used in a wide range of industries, such as home and office construction, automotive, sports and recreation, commercial art, construction, purification services, and marine safety.
We’ll be reviewing these large air compressors based on the following criteria; engine speed and power, pump pressure (PSI), tank capacity and ultimately their price.

We ranked this product at the top because it features optimal air flow at maximum operating pressure. Air flow is indicated by the unit’s SCFM or standard cubic feet per minute.
As airflow goes up, pressure tends to drop. Please take into account the type of tools you will be using with the compressor to determine the correct SCFM and PSI regardless of which compressor you choose.
Buyer’s Guide – Important Things Before Your Buy Commercial Air Compressor
Before committing to a compressor make and model, ask the following questions:
- What is the air flow and pressure?
- How Much power?
- How durable is the compressor?
- Oil or oil-less?
- How good are the cooling systems?
- What about maintenance?
Air Flow and Pressure
As noted, the volume of air flow and the maximum operating pressure, measured in SCFM, should be taken into account. You need to consider the type of tools you will be using with the compressor to determine the correct SCFM and PSI.
Motor power is usually expressed in horsepower (HP). We don’t recommend going anywhere below 10 HP because these compressors are bound to have large tanks.
Plus, 10 HP produces greater pressure as well as greater compression. Determine the air flow and pressure before considering the power.
You need a robust, sturdy compressor because these large products are quite expensive for the most part. Cast iron compressors won’t rust easily. They are heavy duty and can usually tolerate the worst.
Oil vs. oil less
Oil is important in the operation of any compressor as it serves to remove heat generated by the compression process. It also provides a seal in many designs. Oil lubricates the crank and wrist-pin bearings and the sidewalls of the cylinder in the case of piston compressors.
Rings on the piston provide sealing of the compression chamber and control the passage of oil into it, as with piston engines.
Rotary-screw compressors inject oil into the compressor body to both remove some of the heat of the compression process and seal the two non-contacting rotors.
Rotary-vane compressors rely on oil to seal the minute space between the housing bore and the vane tips. Scroll compressors are known as oil-less because they do not normally use oil but, of course, their capacities are somewhat limited.
Centrifugal compressors are in a different league than their positive-displacement brethren and do not introduce any oil into the compression stream.
Makers rely on several approaches to create oil-free compressors. Piston-compressor makers can employ one-piece piston-crank assemblies that ride the crankshaft on eccentric bearings.
This design does away with a wrist-pin bearing on the piston. Piston-compressor manufacturers also use certain self-lubricating materials for the sealing rings and cylinder liners.
Disadvantages Of Oilless Compressors
There are compromises to make whatever you choose. Some of the disadvantages of oil-less compressors are increased wear, more frequent maintenance, heat-management issues, and reduced capacity. An oil-based compressor is a good idea if it is acceptable to filter out oil or simply live with it.
Cooling Systems Of Air Compressor
Large compressors can heat up very easily because they often face heavy loads. This is why you should always check how efficient a cooling system is. Most compressors are equipped with aluminum heads or fans for better heat dissipation.
Is maintenance easy?
You don’t want to be stuck with daily maintenance of such a complicated and huge machine. It’s a good idea to look for compressors that do not require much maintenance or are easy to maintain, as the rotating screw compressors.
Some Additional Factors To Consider:
- Sizing the compressor
- Air quality
Quiet Commercial Air Compressors
There are quiet air compressors out there that can give you the maximum performance you need to get any work done, whether at your worksite, the office, or at home—all without the noise. The quietest and most affordable models are those by Dewalt and California Air Tools. These are at least 50% quieter than the rest.
They also have great reviews from real-life users and product reviewers online. The low prices are another incentive to purchase. Manufacturers have decided to move the market towards quieter air compressors. A compressor doesn’t have to be loud to be good.
Best Commercial Air Compressor Brands

- Brehob Corporation
- Kaeser Compressors, Inc
- Eaton Compressor & Fabrication Inc.
- Werther International

Apart from them, do consider the manufacturers of the other products we’ve reviewed here. Some great 120-gallon compressors ship from China, for example.
The Outdated 100 Gallon Air Compressors
The 100-gallon air compressor is not very common in the U.S Market. Most manufactures discontinued the manufacturing of the 100-gallon air compressor for lack of demand. The 100 gallons is falling between the very popular 80-gallon air compressor, which is used mostly by DIY and small business owners.
The air compressor manufactures realized that most light users will most likely be using an 80-gallon air compressor or the 120 gallons (second best among light industrial users). On the other hand, the big industrial applications will require the 200-gallon air compressor.
Either Way, the 100-gallon air compressor does not have a large market share. Therefore, it was discontinued by most. In our quest, we managed to find only compressors that are shipped directly from China.
We don’t recommend users order those because parts and technical support might be very limited. We strongly suggest choosing a 120-gallon option.

The standard volume and working pressure of the Muye is 4.0-1.3. It can supply 2600 units a day. Produced in a licensed Chinese factor, this is a great quality air compressor tank with a volume of 100 gallons. The tank is for air compressor pistons.
Air receiver tanks are designed to provide a supply buffer to meet short-term demand spikes that can exceed the compressor capacity. They can also dampen reciprocating compressor pulsations, make the compressed air system easier to control and separate out particles and liquids. In some cases, installing a larger air receiver tank to meet occasional peak demands can make it possible to use a smaller compressor.
Air receivers in compressed air systems serve several important purposes:
- Eliminate pulsations from the discharge line.
- Separate some of the moisture, oil and solid particles that might be present from the air as it comes from the compressor or that may be carried over from the aftercooler.
- Decrease wear and tear on the compression module, capacity control system and motor by reducing excessive compressor cycling.
- Offer additional storage capacity made to compensate for surges in compressed air usage.
- Help reduce dew point and temperature spikes that follow regeneration.
- Contribute to reducing energy costs by minimizing electric demand charges associated with excessive starting of the compressor motor. It is good for motor lifespan increasing.
