Air Compressor Buying Guide

Whether you are a home user, private contractors, or commercial enterprise, getting the best air compressor suitable for your needs is essential to accomplish your goals. For example, the average user will never need the size or cost of an industrial compressor, while the private contractor should have done a full unit but is flexible enough to working in a variety of environments.

About Pneumatic Tools

Compressed air is a great way to use almost any type of electric tools. No matter what place the compressor is used in, you will always have the ability to use a variety of tools with a single tap, making it possible to run an air flow on a desk or area labor and then quickly discussed. Pneumatic tools are quieter and less expensive than personal aids. In addition, the use of air as the energy source for the tools do you use more secure and give you a way to control emissions. Pneumatic tools capable of strength and speed that may not be available in equivalent tools powered by electricity or liquid fuels.

Air compressors are ideal for:

  • Build
  • Process the wood
  • Painting and spraying
  • Torque precision applications
  • Sanding and Shaping
  • Inflationary
  • Many other applications

Calculator Basic Usage

On the surface, the Cubic Feet per minute average standard of a compressor seems to be the most important decision, because it determines how much air pressure you can expect at any given time. For commercial purposes and contractors, the SCFM of air compressors to meet or exceed the rating of the tools you plan to use. The simple calculation for this is to multiply SCFM highest assessment tools that you will use in 1.5. Since compression of the compressor is measured in pounds per square inch, comparing with the assessment compressor SCFM when tanks filled to 90 psi. Except for a small air compressor, you can set the desired psi on the tank up to the maximum rating of the compressor, which is why your initial calculation is multiplied by half the pressure forward want.

However, using a variety of tools and also will increase the amount of power necessary compression. To allow multiple tools, you will need to increase the SCFM of air compressors, speed can refill the tank based on engine horsepower compressor, or both. What the two characters mean it seems simpler: SCFM determine the frequency to increase engine power, while HP determines how long the motor has to run in order to fill the tank. Both factors will be influenced by the consideration actually first you have to make, size pool.

Select size tanks

Decide on the right size tank is simple once you have calculated your common needs as required or psi SCFM. Tanks larger size, faster and longer you can work. Once the tank is drained below installed psi. Where pneumatic tools are concerned, a tank that is too small will lead to engine “winding down” as the tank empties. It’s as simple as that. A higher horsepower can offset this slowdown a bit, with the cost of additional wear and tear on the compressor motor. Your goal is to work longer without forcing the compressor to run continuously. If your sole purpose is to inflate a tire on the occasion, you have little or no use of a pool at all.

To explain this, coin-operated compressor like you see in convenience stores not included any tank capacity at all, and a very low rated HP. It may take a few minutes to fill a 32 psi tire or higher with this type of compressor. In contrast, the compressor is used by a commercial tire company can increase a tire almost immediately, because the compressor has a tank that is filled with a larger volume psi desired settings. Think of the tank as a slower ball which release gases and slower as the initial psi drained, which means a large tank will maintain psi needed for a long time.

A small pool, 2-6 gallon, is good for the use of a single nail. If you intend to use multiple nailers, increase the size of the tank that amount for each tool. Similarly, if you use a pneumatic tool that operates at a constant speed, a larger tank will give you smoother, more reliable results.

Pumps weigh

There are four main variations on the type of pump used in the compressor. Each category is designed to provide a particular advantage. The type you need will depend on factors such as your usage and downtime available for maintenance. The required maximum psi for your project will also play a factor in whether you need a single compressor or two stages.

Single stage

Use one or more cylinders that fill-as a single function.

Two stages

The first phase creates an initial value is transferred thugh psi second stage to increase the value of psi. This allows for longer sustainable operation without loss of performance tools.

Free Oil

Lubrication system is provided by using special coated piston and rings. Oil free systems tend to be smaller and lighter, but also have a shorter life cycle than estimated before the compressor has to be rebuilt or replaced.


Like a lawn mower, this type of system has a lubricant tank moving parts of the engine compressors. lubrication system usually bigger and heavier, but is designed for a longer life cycle supply of oil is changed regularly and kept fluid design.

Electricity supply

There are two main ways to provide power an air compressor. DC-powered compressor is available, but not useful for any kind of serious applications. Such compressors do not offer high-speed or pressure you will need a pneumatic tool or spray.

Alternating current

AC compressors are available in both 110 and 220 volt models. Typically, 220-volt air compressor provides a higher rated hp, while 110 volt compressor is limited to 2hp or less. Electric compressors are best for limited-ventilated areas and situations where weight and portability is an insurance.

Electric compressors work best in settings such as:

  • Interior space
  • Uneven terrain or unstable
  • High spatial
  • Hobbies or Home


Compressors operating with liquid fuel strong trend, and has the advantage of being used in areas where DC power is not available. This type of compressor requires more ventilation. In addition, gas supply compressors need to be used at a level, stable environment.

Compressors work best in settings such as:

  • Remote locations
  • Home Building and Job Sites
  • Usage Heavy Duty
  • Commercial applications and industrial
  • Compressors Portability

Portable air compressors

This type tends to be smaller and lighter. Tank size is usually limited to 30 gallons or less. Portable air compressors may not be enough to supply more power pneumatic tools for a long time, but they are inexpensive and work well for home use and situations where the compressor will be needed set over the position on a regular basis.

Stationary air compressors

This type of compressor is fixed to a concrete slab or other platforms, with hose pipe to the different locations. Static compressors often have the containers 20 gallons or more, and can provide sustainable psi with a longer duration. This type of unit is more suitable for commercial applications and industry, where many pneumatic tools are required, or individual instruments must maintain a fixed level of performance for extended periods of time scaffold.
