A two-stage reciprocating air compressor in GA is ideal for most demanding industrial applications. They are much stronger than single-stage compressors and can handle more pressure and more capacity. Today we’re discussing how these compressors work.
Two stage air compressors: With two-stage air compressors, the air is compressed in two stages; in between the stages, the air is cooled.
Stage 1: Air is compressed to medium level, which is the big cylinder/piston. It moves a high volume of air, but at a low pressure.
Cooler: Air is cooled back to a much lower level, making the compressor more efficient and reducing stress.
Stage 2: The air is compressed further to the end pressure, which is the small cylinder/piston. It moves a lower volume of air, but at a higher pressure.
On some models, you can clearly see the two stages, while on others, the low pressure and the high-pressure cylinders are cast in one block, making it look like a single-stage compressor.
Pressure: You need to figure out how much pressure you need. two-stage reciprocating compressors in GA can get up to 175 psi. If you only need 125 psi, it’s better to choose a compressor with a lower maximum pressure, but at a higher capacity.
Capacity: Like with any type of compressor, you need to know (approximately) the amount of air that you will be using before making your decision. If you are unsure about what capacity you need, be sure to review the air compressor buying guide. two-stage reciprocating compressors go up to about 50 CFM (cubic feet per minute); if you need more, a rotary screw compressor might be a better option.
Duty cycle: The duty cycle of almost all two-stage air compressors is 100%, which is one of the reasons they are viewed as being more powerful and durable. This duty cycle indicates that the compressor can run nonstop, without needing time to cool down. In contrast, most single-stage air compressors have a duty cycle of 50% or 75%.
Electrical connection: Since two-stage compressors are much larger than single-stage air compressors, the correct electrical connection is very important. Make sure that you have an adequate power supply available at the place where you want to install your compressor; have it installed by an electrician when necessary.
Some compressors can be purchased with either a one- or three-phase motor, and you can typically choose between 200 volts, 230 volts or 460 volts. Make sure you choose the correct type for your application. Larger two-stage compressors are only available as three-phase machines. Keep in mind that most two-stage air compressors come without any wiring, so you have supply that too.

As with most pressure / splash lubed equipment, air compressors require lubrication to keep them operating efficiently and minimize the impact of wear and tear, as well as to cool and seal internal pump / airend components. By reducing friction, proper lubrication with Gardner Denver compressor oil in GA can reduce heat and lower the compressor’s energy consumption.
While there are oil-free compressors on the market, most models require the use of compressor oil to provide essential lubrication. What follows is helpful information regarding the different types of compressor fluid and how to select the best oil for air compressor products.
While there are several types of air compressor oil products for both rotary screw and reciprocating models, many manufacturers recommend using synthetic oils, as these contain no additives or sulfur that can produce a build-up on valve backs and faces. Key benefits of synthetic oils include the following.
Rotary screw air compressors: In rotary screw compressors, synthetic oils can provide up to 8,000 hours of extended oil service life. They can also reduce the sludge, varnish and other deposits that can inhibit compressor performance and lead to premature wear. Synthetic oils will produce cooler oil temperature and a cooler discharge of compressed air. What’s more, synthetic oils can lead to a reduction in overall oil consumption, which means you won’t need to add oil as frequently.
Reciprocating air compressors: In reciprocating air compressors, synthetic compressor oil will reduce the amount of carbons that accumulate on compressor valves, as well as significantly lower oil feed rates. They also feature higher flash points and higher auto ignition temperatures. Synthetic oils can prevent premature wear on piston rings and packings, adding to the equipment’s life.
When choosing Gardner Denver compressor oil in GA, the first thing to consider is the compressor’s oil viscosity requirements. A 30-weight oil is recommended for compressors that operate in conditions where the temperature ranges from 34° to 100° F. A 20-weight oil is the better choice for colder conditions.
Other factors to consider include:
While you should use the manufacturer’s specifications as a guide, choosing an oil that exceeds the minimum specs – such as Gardner Denver compressor oil in GA - can result in better performance and, ultimately, longer compressor equipment life.
People often forget the importance of keeping machines properly oiled. In the everyday world, people run their cars past oil changes all of the time and then wonder why they begin to see serious mechanical problems.
Industrial equipment and machinery is no different. If you want your industrial air compressor to run as efficiently as possible, it is important to change the oil frequently. Along with frequent oil changes, you should make sure you are using the right oil for your air compressor.
It is good to know why it is important to change your air compressor oil. Oil removes heat from the air compression - this is important to combat overheating in your air compressor and will also allow it to operate longer. Gardner Denver compressor oil in GA also works as a sealant to prevent air from leaking out of the air compressor. Air leakage will cause it to operate less efficiently.
In addition to these two functions, oil keeps all moving parts properly lubricated during operation. The last function of oil is to cool important operating parts of the compressor, another way to prevent overheating and extend the life of your industrial air compressor.
It is important remember that using the wrong oil will have negative effects on your industrial air compressor.
