The most preferred air compressor types are:
- Reciprocating (piston) air compressor
- Rotary screw air compressor
Other types consist of scroll, turbo, rotating vane compressors; however those are mainly utilized for details applications. You can ignore those for now; let’s focus on both primary types of air compressors: the reciprocating compressor and the rotary screw compressor.
THE RECIPROCATING COMPRESSOR
The reciprocating compressor compresses air with using one or more cylinders/pistons. The pistons go up as well as down means reciprocating inside the cylindrical tubes to press the air. For a detailed description, take a look at my reciprocating air compressor.
- Can be low to very high stress, 7-1000 bar or 100-15.000 psi.
- Are of low capability.
- Are created for periodic usage.
- Reciprocating compressors are fairly small compressors. They increase to 10 HP or 7 kW. They are frequently discovered at, or utilized for:
- Do-It-Yourself/in the house.
- Small businesses.
- Building and construction .works).
THE ROTARY SCREW COMPRESSOR
The screw compressor compresses the air inside by two screws or blades that turn in the opposite direction inside the real estate. Air obtains caught in between the blades, and it is pressed. For an in-depth explanation, look into fluidairedynamics.com website.
Rotary screw compressors:
- Are of low pressure, 7-15 bar or 100-215 psi.
- Are of high ability.
- Are developed for constant usages, such as 24 hours a day.
Rotary screw compressor are used for industrial machines. They begin at about 10 HP or 7 kW and rise to greater than 1000 HP or 700 kW. The largest device is almost of 2000 HP or 1500 kW monster of an air compressor!
HOW TO KNOW WHAT’S THE RIGHT KIND OF AIR COMPRESSOR FOR YOU
When your requirement is a small amount of air and doesn’t need much use of compressed air constantly, get a reciprocating compressor, for example in a workshop, for air tools. If you do have some huge tools that require a great deal of air, however, you utilize them just occasionally, it’s much better to mount a bigger pressed air receiver than to buy a bigger reciprocating compressor or perhaps a rotating screw compressor.
If your compressor stalls greater than 60% of the moment, it’s typically better to get a reciprocating compressor. Piston compressors do not mind stalling, even like not to run regularly. However, you should always remember that when you do use compressor air, the capability of the reciprocating compressor is big sufficient.
If you need high stress above 1500 psi, a reciprocating compressor is the only way to go. Screw compressors just go up to about 150 psi (10 bar) maximum.
