Did you know that the air compressor market is expected to be worth more than $40 billion by 2024? Air compressors are used in almost every industry for a variety of purposes, from extracting gas and oil to producing electronics.
If you want to benefit from compressed air technology in your business, you may be wondering which compressor is best for you. After all, there are many types of air compressors on the market.
Keep reading our in-depth article below to see what is available in 2020.
1. Displacement Compressors
There is an air compressor for every type of task. Portable air compressors can be taken on to sites or from workshop to workshop. Others have a specific specialty such as lightweight construction.
Displacement compressors offer very high pressure in a small frame. They contain a cavity that is filled with air or another gas. This cavity then begins to shrink.
The pressure on the gas is increased as its volume decreases. An example of this is a piston compressor. As the piston travels up the cylinder, the volume of gas is forced to shrink.
This type of compressor has many advantages. It is able to achieve high levels of compression.
However, since this is created by a moving part, the level of pressure can be easily regulated. In the case of a piston compressor, you simply halt the progress of the piston when it reaches the pressure you desire.
2. Rotary Screw Compressor
A rotary screw compressor is also known as a double rotor compressor. This uses a different technology to the displacement compressor.
In a rotary screw compressor, the air becomes trapped between male and female rotary profiles. As the engine turns and contracts, the air is pushed into a smaller and smaller space.
This process compresses the air until it can fit into the compression chamber cavities. This air is then stored in compressed form until used.
3. Dynamic Compressors
Industries that use high volumes of air may use dynamic compressors to achieve their goal. This is the same technology that is used in jet and turbo engines.
This process maintains the consistent movement of air. An impeller initially speeds up the flow of air and directs it through a diffuser.
In the diffuser, the airflow is slowed down, which results in an increase of pressure. This pressurized air is then redistributed as needed.
The kinetic energy within the air is converted into air pressure. This type of air compressor is typically used in the automotive and petrochemical industries.
4. Oil-Free Air Compressors
Most air compressors require a chamber with moving parts to contract the space that holds the air. However, the moving parts require lubrication.
Often engineers apply oil to seal the process to efficiently compress the air. A problem arises when the oil mixes with the air. Microscopic drops of oil can be expelled with the air and land on the product that the air impacts.
An oil-free compressor from commercialaircompressor.ca will use similar technologies to those we describe above but may use alternative sealing chemicals.
Manufacturers may also add filters to ensure that the machine expels the minimum amount of pollutant materials.
Oil-free compressors may be more expensive initially. However, the cost of running the machine is usually lower than other types of compressors.
5. Variable Speed Driven Compressors
If you are regularly using air compression in your work, you will need consistent pressure and efficiency. This is easier to say than to do.
In a traditional air compressor, there is a simple on and off switch. When on, the machine is creating compressed air. When off, it stops.
However, when working, you may need different levels of air pressure. You may also want to be able to leave the machine running without creating compressed air but not suffer significant loss of energy and fuel.
Variable Speed Drive (VSD) technology can help you to do just this. A VSD unit will actually adjust the motor to the amount of air required. When you need a lot of highly compressed air, it will increase the engine speed.
When demand decreases, it will reduce the engine speed to save on energy and fuel. This can lead to significant savings.
6. Reciprocating Compressors
If you simply need a compressor for occasional or lightweight work, a reciprocating compressor may be for you. You can typically find these in garages and personal workshops.
These are small units with a piston that moves inside a cylinder to create pressurized air. Depending on the need, the compressor may have a single or multi-stage option.
The latter allows for a greater degree of control of pressure levels.
A multistage compressor will allow for higher levels of pressure. A single-stage compressor may be ok for personal projects. However, if you will be using your compressor for woodworking light construction, you will need a multi-stage compressor.
These can provide up to 30 horsepower (HP) of pressure.
7. Axial Compressors
Finally, if you need extreme pressure levels, look no further than axial air compressors.
These are not your ordinary workshop compressors but can create the thousands of horsepower high level of air pressure that is needed for ships and planes
