What Is Oil Free Air Compressor
An oil-free air compressor operates without using oil in the compression chamber. This distinction is crucial for applications where air purity is paramount. Unlike traditional oil-lubricated compressors that rely on oil to act as sealing, for lubrication and to cool the compressed air.
An oil-free air compressor is a type of air compressor that does not require oil lubrication. These compressors use advanced engineering techniques and materials to achieve frictionless operation, which eliminates the need for oil-based lubrication. Oil-free air compressors are commonly used in environments where oil-based lubricants are not permitted, such as in food processing, pharmaceutical manufacturing, and clean room environments.
Benefits of Oil Free Air Compressor
In certain industries, strict cleanliness standards must be met to ensure quality production. For applications like these, an oil-free air compressor isn't just beneficial, it's necessary. In order to ensure manufactured products are clean and safe, there can't be any oil particles coming out of the machine and contaminating them.
Oil-injected air compressors require regular oil changes, usually after every 200-500 hours of use. They may also need air/oil separation and filtration treatments to remove oil aerosols. All of that maintenance can add up and cause your business time and money.
Most oil-free air compressors are less expensive to begin with, but that can of course vary depending on which product, size, or horsepower you choose. However, since oil-free air compressors require less preventative maintenance, they can offer a much lower cost of ownership.
Oil-injected air compressors require more power to heat up and start working because oil is viscous and difficult to get moving, especially in cold conditions. With an oil-free air compressor, that extra start-up time isn't needed, so you can get production started without delay.
Oil-free air compressors are more environmentally friendly than their oil-injected counterparts simply because they don't release oil contaminants into the air. If you're using an air compressor for multiple projects a day, and for extended periods of time, going oil-free could lessen your environmental impact dramatically.
Type of Oil Free Air Compressor
Scroll Compressors
Scroll compressors are a popular type of oil-free air compressor that use a unique scroll design to compress air.
Piston Compressors
Piston compressors are another common type of oil-free air compressor. These compressors use a series of pistons to compress air, and are available in both single-stage and two-stage models.
Rotary Screw Compressors
Rotary screw compressors are a popular choice for large-scale industrial applications, such as power generation and oil and gas processing. These compressors use two rotors to compress air, and are highly efficient and reliable.
Centrifugal Compressors
Centrifugal compressors are a type of oil-free air compressor that use centrifugal force to compress air. These compressors are known for their high flow rates and are often used in large-scale industrial applications, such as chemical and petrochemical processing.
Diaphragm Compressors
Diaphragm compressors are a type of oil-free air compressor that use a flexible diaphragm to compress air. These compressors are often used in applications where high levels of purity are required, such as in the medical and pharmaceutical industries.
Oil free air compressors either have no mechanical contact inside the compression chamber or use alternate materials to protect the mechanism without lubrication.
Most oil-free compressors utilize other materials like water or a Teflon coating to keep the mechanism running smoothly. Because the lubrication of bearings and gears is all external to the compression chamber, proper sealing prevents any oil from contaminating the compressed air. The result is a 100% oil-free air supply. Some oil-free designs have even removed metal-to-metal contact within the compression chamber, eliminating the need for oil-based and synthetic lubrication altogether.
Energy costs are minimized because there's no need to increase force - some fluid-flooded units can see a downstream pressure drop due to filtration.
Those savings can be very tempting. To see if you can make use of the oil-less compressors, you'll need an understanding of how the compressors work, how they compare to other types of models and in which applications they work best.
Oil free piston air compressors typically last around 10-15 years, while oil-free rotary screw compressors tend to last around 20-30 years. You can generally expect anywhere from 2,000 to 8,000 hours of service. However, the lifespan depends largely on maintenance, proper care, and usage habits.
A common criticism of oil-free compressors is that they don't have the lifespan of their oil-lubricated counterparts. While this may be true of older models, it's not exactly fair to say of today's oil free compressors. The technology has improved significantly in recent years and only continues to be improved.
That being said, most oil free compressed air isn't intended for long-term continuous use applications. In other words, they're not ideal for running for several hours at a time. The permanent lubrication materials will eventually wear out. So while oil free compressors may not provide the same number of actual service hours as oil-lubed compressors (typically around 15-20K hours), they will likely last the same number of years, since they're meant for shorter bursts of service.
Medical and Pharmaceutical
In medical and pharmaceutical applications, cleanliness is a critical factor in the quality and performance of the products. The product or manufacturing process will often dictate the risk tolerance for any trace contaminants such as oil or moisture. It is key to be able to minimize that risk to the general population. Because of the critical nature of these risk factors, every touchpoint of the manufacturing processes such as tablet coating and product drying must be reviewed, including the risk from compressed air.
Food and Beverage
New requirements outlined in the FDA's Food Safety Modernization Act, Global Food Safety Initiative, and British Compressed Air Society Code of Practice, reinforce the need for using clean air in the manufacturing process to avoid product contamination, which can lead to product recalls and a damaged brand reputation.
Electronics
For applications including PC board cleaning, delivering clean, dry compressed air is critical to minimizing trace contaminants in the end product. Requiring the highest class in air purity allows manufacturers to protect sensitive instrumentation and their finished products.
Textiles
A quality stream of compressed air for spinning machines and air-jet looms is crucial to prevent fabric staining and production loss. Mandating the highest class of air purity is essential for delivering high quality, oil-free, manufactured products.
Are Oil free Compressors Better than Oil-lubricated Compressors?
Oil-free and oil-lubricated compressors both have their advantages and disadvantages. However, in some cases, oil free compressors are better than oil-lubricated compressors, and in some cases, these aren't.
Air Contamination
Oil-free compressor air contains fewer contaminants than oil-lubricated compressor air because the oil in the piston of an oil-lubricated compressor causes more contamination to the compressor air.
Weight
Manufacturers design the parts of oil-free compressors in such a way that these have less weight than the oil-lubricated ones.
Cost
Oil-lubricated compressors would require additional filter units to separate the oil from air, and so these could often cost more than oilless air compressors.
Maintenance
Oil-lubricated air compressors require regular oil lubrication. It means oil-free compressors need less maintenance than oil-lubricated compressors.
How to Maintain an Oil Free Air Compressor
To ensure the smooth operation of an oil-free air compressor, proper maintenance is essential.
