Key To Choose Air Compressor For Your Needs

choose air compressorChoose air compressor depend on your job demands. Before you decide which type, please define how and where will you be using your compressor? If you want to use for heavy duty use in your workshop, you can choose a model with powerful motor and larger tanks (>30 gallon). If you just want to inflate tires and handle occasional home projects you can get the smaller consumer models.

Key To Choose Air Compressor

Below we will explain the factors to choose air compressor, so you can choose the Best Air Compressor for Home Garage for your needs. There 5 factors to choose air compressor :

1. Portability

Portable model (2-30 gallon tank) are light enough to carry around or have wheels, but be careful you don’t sacrifice performance for portability. Stationary model are designed to be bolted into a fixed area and wired directly to a building’s electrical circuit. Generally, they’re equipped with 60-80 gallon tanks and 4-10 HP motors. It’s ideal for garages and workshops.

2. Power Source

There two type: electric or gasoline. Electric compressors are the most common. It’s easy to use in any area with a ready electrical supply. This model is better choice for indoor applications. Gas-powered compressors are a good choice for areas where electricity is limited or unavailable. Generally used by builders and remodelers because of there high output and convenience at the jobsite.

3. Airflow

Which is a combined function of the power and efficiency of the compressor and the capacity of the air pump. The volume of air a compressor delivers is measured in cubic feet per minute (CFM). The actual CFM changes depending on the pressure of the air in the compressor (measured in pounds per square inch, or psi ). Multiply the highest tool rating by 1.5 to get the minimum compressor CFM for your needs. Compressors generally have horsepower ratings (HP) which indicates how powerful the motor is. Usually higher horse power motors yield greater psi and are capable of carrying a heavier workload

4. Tank Size

Compressor storage tanks are rated in gallons. Larger tanks store more compressed air at higher pressures. If you will be using air tools that require a high volume of air for continuous use, than you should consider a larger tank.

5. Noise

Listen before you buy. It would be worth to buy an electric  compressor that usually less noise. If you want to buy gasoline compressor, please remind to choose Oil-lubricated compressors . The oil lubricates the moving parts in the pump to prevent excessive wear and also less noise.

Type of Air Compressor

Based on availability of tank to store compressed air, Compressor can be divided by two type of air compressor :

1. Piston-type compressors

This compressor have tank to store compressed air. Motor start to fulfill tank with pressured until pressure in the tank reaches a specified level, then the motor shut off . The motor restart again when pressure inside the tank drop.

There are two kinds of piston compressors:
1. Single-stage compressors have one piston that compresses air and delivers it to the tank.  Single-stage compressors are adequate for most home users since a maximum rating below 150 psi.

2. Two-stage compressors have two pistons that compresses and deliver air to the storage tank. The first piston compresses the air and pushes it through a check valve to the second piston. The second piston further compresses air and save it to air tank. The two-stage system is usually found on commercial heavy-duty compressors with maximum ratings above 150 psi.

2. Portable air compressors

Type Air Compressor - PortableThis compressors are the smallest and lightest compressors available. These compressors don’t have storage tanks, so they must run continuously to supply air. Portable compressors power caulk guns, glue guns, small spray guns, and can inflate sports equipment and tires.



After you well-known about type of compressor. We suggest you to know several factors when you are buying an air compressor.  But let us take a look at each of them in brief:

Source of power: There two alternatif: electric and gas. Electric air compressors are ideal for indoor applications.
Gas air compressor provide high performance but emit fumes so they are best used outdoors.

Portability:  There are two options: portable or  stationary. Please choose models based on what you intend to use it for and which one is more convenient to use.

Size: There are different tanks sizes ranging from 1 gallon to 80 gallons. The smaller size of the tank, the cheaper compressor for the money.
