How to select An Effective Air Compressor

Here are 10 things to think about before you go to the store to buy a reciprocating compressor.

Types

Basically there are 3 types of compressors: Single stage compressor; two compressor stages; Twin compressor. According to best air compressor reviews, it is hard to define the best type of air compressor among three mentioned-above types.

Single unit compressor stage in a stroke, from ambient to pressure end. They usually go up to 20 CFM (cubic feet per minute) at a pressure of 125 psi

For more power, you will need a two-stage compressor. A two-stage compressors use a two-stage air compression end pressure. This means that your compressor will have two cylinder / piston.

The big cylinder is a low-pressure stage, while the small cylinder is the high season. In between stages air is cooled.

Whether you need a single compressor or the final two stages depending on the size (cubic feet per minute) you need.

The Capacity and Pressure

Capacity (CFM) and pressure of air compressors two specifications is most important.

To learn the features that you need, just add the air consumption of all air tools that you will use.

To find out what pressure you need, check the specifications of air tools you plan to use. The highest pressure requirements will impose pressure you need.

It’s always smart to buy a compressor has the capability to provide more than you need. You will probably add more tools in the future, and almost all of the compressed air system will have a leaky faucet or coupling somewhere!

Horse power

You do not need to know the capacity of the compressor.

The horsepower is a result of the pressure needed and capabilities that you need, not the other way around.

Do not look at horsepower. Looking at capacity (CFM) and pressure (psi).

Electrical connections

You will not be the happy owner of a new compressor first comes home with an air compressor which he was unable to wire up!

Voltage know that you have at home. To know the maximum current your wiring system can handle. Do you have a phase or 3-phase power supply?

Install additional wires (or even 3 phase electricity installed in your home!) There may be more expensive than its own air compressor!

Noise

A reciprocating compressors make a lot of noise. Always check the noise level of the compressor before buying one. If you buy a compressor in a store, ask them to run it, so you can hear what sounds like.

To reduce noise, you can make an enclosure around the compressor. Make sure you add enough vents a compressor generates a lot of heat, so cooling is required!

Swimming

Most reciprocating compressors come with a 40 – 80 gallon tank, which is good. A larger tank size is always better. A larger tank means having a larger pneumatic buffer.

A larger air buffer is useful when you use the major tools that use the air more than the capacity of the compressor. The pressure will fall slower with a larger air tank.

Pneumatic Filters

Pneumatic hot, wet and dirty. Depending on your application, you need to filter it and remove water and oil.

If you use compressed air to spray paint, you do not want oil, water or dust in your compressed air, the air should be clean.

If you only use it for powering air tools, you do not want water in your compressed air, but you do not really care about oil.

There are filters available for removal of water (drops), oil and dust. For even compressed air dryers, you need to get a compressed air dryer.

Other Options and Accessories

Pressure regulator – to adjust the pressure tank back pressure stability, low

The size and number of air connections: vertical or horizontal tanks; Manual or automatic drain

Weight

Most (online) stores will drop your new air compressor on your driveway. You will need to bring it into your garage or wherever you want to place it yourself.

Your new air compressor is likely to go on a wooden pallet. You can choose to keep it on the pallet, or removing the pallet.

Duty Cycle

The duty cycle is the percentage of time your compressor can run.

Most single stage compressor has a duty cycle of only 50%. This means that when you run your compressor for 5 minutes, it takes about 5 minutes to cool.

Most dual-stage compressor has a duty cycle of 100%. They can run 24 hours a day as needed.
