Atlas Copco Oil-Injected Air Compressors

Picture yourself behind the wheel on a scorching day. The dashboard warns of low oil, signaling that an oil change is imminent. As the engine heats up, you perform the oil change, allowing it to circulate and cool down the vehicle. The engine runs more smoothly now, benefiting from the lubrication, which ensures it operates efficiently and reliably.

Now visualize an air compressor in a furniture manufacturing setting, towering six feet high and five feet wide. By using oil to lubricate the air compressor motor, the entire manufacturing process functions seamlessly. The air, which heats up during compression, is kept cool by the oil. As a result, the compressor operates optimally, ensuring the furniture production is smooth and efficient while reducing energy usage and streamlining the manufacturing workflow.

This exemplifies the application of an oil-injected air compressor! These machines play a vital role in driving a multitude of applications across various industries—many of which would struggle to operate effectively without oil-injected compressors.

Types of Rotary Screw Compressors

There are two categories of rotary screw compressors. The first type utilizes oil for sealing and lubrication of the screws, commonly known as oil-injected compressors. These compressors are generally more affordable and provide higher power because the mechanism can be driven by turning just one screw rather than two. The oil also serves as a sealant, preventing air leaks.

Oil-injected compressors are more complex due to the fact that they perform dual functions: they must compress and release air while simultaneously pumping, cooling, separating, and refining the oil utilized in the compression process. The oil is reused continuously through recycling.

Conversely, oil-free compressors do not employ oil in their compression process. Instead, the screws are spaced closely to form a sufficient seal for compressing air. Due to the possibility of air leaks, these compressors generally possess lower power compared to oil-injected models. Nonetheless, they are essential in applications where air contamination is unacceptable, such as in medical research and semiconductor fabrication.

Advantages of Using a Rotary Screw Compressor

Rotary screw compressors are fascinating because they provide a constant flow of compressed air. This feature eliminates the need to pause for the machinery to re-pressurize, making them ideal for power tools like jackhammers that win construction workers uninterrupted power.

Furthermore, these compressors usually operate at lower noise levels compared to alternatives on the market. Although some noise is produced during the air compression by spinning screws and subsequent filtration, this sound is generated continuously, leading to a more manageable noise level over time.

Additionally, rotary screw air compressors can produce large quantities of air at elevated pressures. Unlike piston compressors, which are constrained by the volume of their piston chamber, rotary screw compressors do not rely on pistons, allowing for a continual flow of pressurized air without storage limitations. Typically, these compressors can achieve pressures around 125 psi.

Disadvantages of Using a Rotary Screw Compressor

Although rotary screw compressors tend to have a higher initial investment than others on the market, their advanced and robust engineering justifies the cost. It's not uncommon for these compressors to exhibit remarkable durability. Investing in a more expensive option may yield a lifespan up to four times that of a cheaper competitor. Therefore, many manufacturers offer generous warranties, including lifetime guarantees, to reinforce their confidence in product reliability.

Due to their intricate designs, rotary screw compressors can necessitate skilled technicians for repairs. While malfunctions are infrequent, correcting them can prove costly and time-consuming. However, with a solid warranty in place, you can alleviate concerns about repair expenses.
