Introduction
Compressed air is a vital utility in many industries, from manufacturing to healthcare. However, the presence of oil in compressed air can lead to contamination, which can be harmful to both machinery and products. Oil-free compressors are designed to provide clean compressed air, free of any oil contamination. In this article, we will explore the considerations to be taken into account when buying an oil-free compressor for your specific application.
Advantages of Oil-Free Compressors
1. Avoidance of Contamination
Oil-free compressors eliminate the risk of oil contamination in compressed air systems. This makes them ideal for applications in industries where air purity is crucial, such as food and beverage, pharmaceuticals and healthcare.
2. Low Maintenance
Oil-free compressors do not require oil changes, which reduces maintenance costs and downtime. Also, they do not generate oil mist, which can settle on surfaces and machinery, resulting in additional cleaning costs.
3. Environmentally Friendly
Oil-free compressors do not emit any harmful chemicals or greenhouse gases, making them a more environmentally friendly option than oil-lubricated compressors.
4. Energy Efficient
Oil-free compressors are designed to operate more efficiently than their oil-lubricated counterparts. This translates to lower energy consumption, which can result in significant cost savings over time.
5. Longer Life Span
Oil-free compressors are less prone to wear and tear than oil-lubricated compressors. This results in a longer life span, which reduces the need for replacement and associated costs.
Working Principle of Oil-Free Compressors
Oil-free compressors use a variety of methods to generate compressed air without the use of oil. Two common types are scroll compressors and screw compressors. Scroll compressors work by using two interlocking spirals to compress the air. Screw compressors use two rotating screws to compress the air.
Choosing the Right Oil-Free Compressor for Your Application
1. Determine the Required Airflow
The first step in choosing the right oil-free compressor is to determine the required airflow for your application. This is typically measured in cubic feet per minute (CFM) or liters per minute (LPM).
2. Consider the Required Pressure
Another important consideration is the required pressure for your application. This is typically measured in pounds per square inch (PSI) or bar.
3. Evaluate the Duty Cycle
The duty cycle is the percentage of time the compressor will be in use. Some applications require continuous operation, while others may only require intermittent use. This will affect the type of compressor required.
4. Assess the Noise Level
The noise level of the compressor is another important factor to consider, especially if the compressor will be located in a noise-sensitive environment.
5. Check for Any Additional Features
Additional features, such as air dryers or filters, may be required for specific applications. Check if the compressor has these features or if they can be added as an optional extra.
Installation of Oil-Free Compressors
Installation of oil-free compressors is similar to that of oil-lubricated compressors. However, as oil-free compressors do not require oil changes, the installation process is simpler. It is important to ensure that the compressor is located in a well-ventilated area with sufficient clearance for maintenance and repairs.
