The Three Basic Types of Air Compressors

The Three Basic Types of Air Compressors

Air compressors come in three basic types: oil-free, rotary screw, and natural gas. Let’s discuss the differences between each. Which one is best for you? Then, decide how you will use it. The right choice for your needs will depend on the application. Read on to find out the pros and cons of each type of compressor. They can help you get the job done. Axial and rotary screw air compressors are the most common.

Natural gas

One type of air compressor is made from natural gas. This gas is compressed and used in industrial settings. Furthermore, there are two types of natural gas compressors: screw compressors and reciprocating compressors. Each type works in a slightly different way like the Air Compressor Products Jacksonville, FL. They can be used for various applications, depending on the gas volume and the pressure required. Natural gas compressors may be used for different pipeline stages, including a wellhead, gathering system, and instrument supply.

There are several advantages to natural gas air compressors. Moreover, they are extremely efficient and emit virtually no carbon monoxide. They produce nearly 45% less CO2 than coal and oil. They are also relatively cheap, with many experts predicting continued decreases in the cost of gas until the year 2035. Additionally, the compressors are heavy-duty and offer high efficiency. As a result, they can save up to 50% in utility costs each year.

The natural gas stream is directed to the individual compressors through yard piping. Computers regulate the flow of gas to match the number of compressor units with the required air pressure. Most compressor units work in parallel, providing additional air pressure and restoring full operating pressure. Naturally occurring gas is abundant in the world. It’s the second most abundant fossil fuel after oil. As a result, there are a lot of uses for natural gas.

Oil-free

The market for oil-free air compressors is growing at a considerable pace across the globe. As the need for clean air grows, manufacturers focus on reducing operating costs and maintaining quality products while minimizing environmental impact. Oil-free air compressors help meet these goals, offering lower energy costs and reducing the risk of entrained oil carrying over. They also reduce the possibility of product contamination. To gain a competitive edge, manufacturers should invest in oil-free air compressors.

Oil-free air compressors are quieter than oil-lubricated units and require less maintenance. They are also easier to transport since they have fewer moving parts, reducing the risk of breakdowns. And, since they have fewer moving parts, they produce lower noise and vibration. Therefore, oil-free air compressors are an excellent choice for businesses that require a high degree of air purity.

The lubrication process in an oil-free air compressor differs from that of an oil-injected unit. The lubrication process in an oil-free air compressor involves an oil cooler or filter that removes dirt and debris that can clog the gearbox. Moreover, since oil-free air compressors are usually air-cooled, they don’t require oil to operate. In addition to this, they are also commonly equipped with an external fan that reduces noise and vibration.

Rotary screw

A rotary screw air compressor works by compressing air through a two-rotor design. The main rotor and secondary rotor mesh together within a dual-bore one-piece housing. Helical lobes and grooves characterize them. The inlet and discharge ports are located at the top and bottom of the housing, respectively. This inverted diagram shows both ports. A rotary screw air compressor can operate in a variety of extreme environments.

Typical oil-injected rotary screw air compressors inject liquid into the compression chamber to keep the screw unit cool and reduce the risk of leaks during the discharge process. Oil-injected rotary screw air compressors are most commonly used. The oil serves several purposes in this system, including lubricating the components, cooling the compressor, and trapping contaminants. Therefore, synthetic oil is recommended for the rotary screw air compressor. In the oil-injected rotary screw air compressor, lubricating oil is injected into the compressor’s motor.

The efficiency of a rotary screw air compressor is the primary reason they’re more popular than their reciprocating counterparts. They’re capable of keeping up with high demand and are generally used around the clock. Some models are even Energy Star rated. These compressors use twenty to thirty percent less energy than comparable reciprocating air compressors. Their rotors are manufactured to tight tolerances. Variable speed drives, turn valves, and on/off-line/off-line controls allow the compressor to adjust its speed to the demand.
