The air compressor is an industrial tool that allows exploiting, for the most varied tasks, a jet of air at pressure, and therefore at a discharge speed, much higher than the normal atmospheric pressure.

Like many other tools that use air pressure, for example, high-pressure cleaners or as the large sector of pneumatic tools, the compressors are truly versatile tools capable of simplifying the work of the user.

Be it a simple hobbyist who needs the compressor to clean and remove dust from a particular surface, or a professional who requires high discharge pressures to inflating tires or lifting heavy materials, the compressor proves to be a fundamental aid every day.

Right here we have listed out some of the best and advanced air compressors that are listed below.

Buying Guide to Select the Best Air Compressors

Why Must It Not Be Missing in Our Home?

An air compressor is a versatile tool among the most useful that a hobbyist and a professional can use to do their job.

As for domestic use, they allow you to do small but valuable jobs, such as inflating the inner tubes of any vehicle, supporting the lover of do-it-yourself in their work. We think of painting, sandblasting, the possibility of engaging work tools that use pneumatic propulsion for their operation.

This aspect is not a detail, in fact, unlike an electric tool, a work tool that uses air pressure to perform its exercise guarantees more excellent reliability and can undergo higher workloads without suffering a drop in performance.

This has greater relevance for a professional, but it makes the difference for a DIY enthusiast who uses tools, perhaps of low power, which, however, need higher reliability and continuity of operation.

Imagine a precision mechanics laboratory with an amateur purpose, which involves the use of presses and cutting machines, professional column drills whose power is contained about the type of use, will have all the advantages of air supply.

For eliminating vibrations and noise while working—a fundamental characteristic of all those instruments that aim to provide a precision operating exercise. These machines are used for Cleaning the places with high-pressure air same like the Vacuum cleaners.

As far as the industry is concerned, they have a massive application, mainly to operate the most different work machines, such as pneumatic hammers or cutting tools that require a great deal of power from the compressor to run at full speed in a performing manner.

As we see, the areas of use are the same for a professional as a hobbyist, what changes is the nominal power, which the type of tool requires.

The field of use is broad and transversal, and highlighting a boundary between amateur and professional use is not simple and perhaps not even useful since the needs of both over time are increasingly approaching each other.

In this regard, we aim to describe both categories to give you further data useful for your evaluation of the purchase of an air compressor.

How Does a Compressor Work?

There are many classes and sizes of air compressors; we begin by defining what they are and what are the primary intended uses, then we will analyze in detail the main technical characteristics.

Let’s start with the basics: an air compressor is a tool whose operation is based on the production of air, which is compressed in a vessel and released at variable pressure according to the need for use. The free air can be used freely or as a propeller to operate the most various work tools.

Technically we can describe the operation of an air compressor in this way: they are machines that use mechanical energy to transform it into pneumatic power.

Once the operation is understood, it is easier to identify all the possible applications. They are mainly used to inflate inner tubes, to generate electricity, are the basis of the operation of refrigeration systems.

If we want to indicate the use of this high-level technology, with the sole purpose of highlighting its versatility, we can mean aircraft turbo-reactors.

Technical Aspects of Being Evaluated for The Purchase:

To choose an air compressor, we have to take into consideration various technical aspects that determine both the performance as the most suitable use for each model instead of another. Power is the main characterization feature of an air compressor.

Power:

Air Compressor up To 2 Cv: air compressors up to 2 HP are of modest power, this limits them to domestic use for small painting jobs, inflating mattresses, balls and the like.

However, let’s not be fooled only by the modest power; since it is not to be considered a defect, it would be completely useless to buy an extremely powerful air compressor for the domestic uses indicated above.

The power is functional to the intended use of the market that this type of air compressors are designed to serve.

Air Compressor up To 4 Cv: an air compressor up to 4CV is the best compromise if we are looking for an instrument that can serve us both for domestic use and for professional jobs that require higher reliability and above all, precisely, power.

Air Compressor Above 4 Cv: air compressors above 4CV are professional products designed and manufactured to serve the work of a professional.

Consequently, to this first distinction between air compressors as regards the power, and therefore the intended use, we go into detail by analyzing some critical technical characteristics.

The main technical aspects of an air compressor to be evaluated before purchase are 3:

  • how much air pressure is needed, this parameter is expressed in BAR;
  • quantity of air that can be compressed, i.e., the volume, and is expressed in l / min or m³ / min
  • what power do I need, given in CV, HP, or KW?

Air Pressure: it is the pressure with which the compressor works at full speed, measured in BAR.

Volume: it is the capacity that the compressor has to compress the air in a given space of time and is measured in liters per minute.

Power: this is the working capacity of the air compressor and is measured in hp or kW kW

In practical terms: the higher the power of the compressor, the greater the air that the instrument will be able to provide as a useful means for carrying out the work.

The most common standards work at 6.2 BAR, 6.2 BAR, and 8.2 BAR; of course, there are more and less powerful machines, but these indicated concern the largest market share.

As for compressed air, there are some consumption correction coefficients that we haven’t talked about yet. These can be:

  • Use Coefficient;
  • Simultaneity Coefficient;
  • Migration Coefficient;
  • Operating Cycle Coefficient.

When there are many instruments, of different powers connected, potentially or simultaneously, to the compressor, it is advisable to size the machine in the best way so as to be able to take care of the air supply that all the equipment requires if they started operating at the same time.

To avoid a drop in performance during the work, when choosing an industrial compressor, simply increase the consumption by 30% more, adding it to the general calculation that is carried out.
