Oil-Free Air Compressor vs Oil Lube Air Compressor

As you can visualize, while internally, they function a bit differently, both types of air compressor achieve the same ultimate effect.

They differ in matters of lubrication, performance, and internal design.  Oil-free air compressors are more environmentally friendly.

In conventional air compressors, the oil used for lubricants can often time linger in the local air as a pollutant, so proper ventilation is always recommended when using them.

Due to their design, oil-based compressors are often more suitable for use in warmer climates types. Because they use a lubricant system, they tend to have a much higher RPMs compared to their oil-free counterparts.

Lighter Applications 

Think of it as a diesel truck vs. a gasoline car. One is designed for really high-end industrial-scale usage, while the other is more frequently used for smaller scale and intermediate work, depending upon the model.

Oil-less air compressors operate at much lower RPM, again depending upon the model, and are quieter than traditional compressors for the most part.

Oil-free air compressors are much more superior for residential and small commercial use and are far more versatile overall. They are usually much more portable because they require no extra materials such as oils and filters.

By nature of their design, they are typically much more suitable to be used in colder climates than traditional compressors. 

Advantages of Oil-Free  Air Compressors

One of the major benefits of oil-less air compressors over their manually-oiled counterpart is its lower short term maintenance demands.

Overall, an oil-free air compressor requires less maintenance, routine checkups, and adjustments to keep it running smoothly.

Modern oil-free air compressors feature quiet motors. That peaceful nature often implies efficiency, and that definitely rings true in this case, as most modern oil-free air compressors tend to be more efficient and cleaner than oil-using models. 

Oil-free Vs. Traditional 

Oil-free air compressors are compressors that are capable of fulfilling everything that a conventional oil-based air compressor can, but without the need for frequent oil changes and annoying daily maintenance.

They are generally lighter, and they function just a bit different from their oil burning counterparts. The standard design focus of oil-free air compressors is efficiency and higher cleanliness through a pre-lubricated design that removes the need for the application of oil.

Traditional air compressors are usually constructed in a way that they depend on an external lubrication system to keep them running.

In contrast, oil-free air compressors do not use oil on the cylinder walls. A relatively new innovation, oil-free air compressors depend on self-lubricating materials that allow their piston to slide smoothly in their cylinders.

Environmentally Friendly 

Because of the absence of oil in the system, oil-free air compressors provide cleaner air output. This makes these air compressors much more environmentally friendly than their oil-breathing counterparts.

In most piston-type oil-free air compressors, lubrication is replaced by a Teflon or silicone coating that protects the moving parts. Oil-free compressors also typically rely on grease that is in their sealed bearings.

Lower PSI

Most oil-free air compressors range between 100 to 135 PSI, and some have a maximum air pressure of up to 150 PSI.

On the other hand, traditional air compressors can get up to 200 PSI.

How do Oil-Free Air Compressors Work?

The process of how these compressors work is quite complex internally, yet for users, their operation is entirely straightforward. The process starts by pulling in air from the outside through a valve and optionally, an air filter.

After this, the low-pressure compressor element begins to compress the air, while other parts cool the air to render it safely usable.

A piston does the work of shifting the newly compressed air to where it needs to be for further compression. The compression process generates quite a bit of heat, which is where a cooling system comes in.

Most air compressors use some sort of inter-cooler system to cool down the recently compressed air. This not only makes the air cool enough to be used, but it also keeps the machine itself from overheating and prematurely wearing out.

Due to condensation, many designs use a filter to remove excess water to keep air quality high.

Once cooled, further compression continues in the main chamber. Additional cooling is conducted in what is called the after-cooler.

When the main chamber runs lower than a specified level, oil-free air compressors will start this process over automatically to maintain a set air-pressure in the tank.

Frequently Asked Questions.

What’s Better: An Oil-Less Air Compressor or a Conventional Model? 

Which type is better strongly depends upon the needs and project context.

Those who require an air compressor that has low maintenance needs and is willing to accept a slightly shorter operational lifespan should consider buying an oil-free compressor.

Generally speaking, pretty much any short-term or low-intensity project that requires compressed air is likely to be a good fit for an oil-free air compressor.

On the other hand, somebody who doesn’t mind the frequent upkeep and higher maintenance costs, and needs a slightly more extended service life should consider getting an oil-based model.

Best Oil Free Air Compressors

Oiled air compressors are excellent for large teams working on long-duration professional projects that require compressed air. More people can regularly keep track of the machine’s needs in these situations because it serves as a critical tool in high-dollar projects that usually involve lots of people.

So more staff can more easily ensure a constant supply of the necessary oil and maintenance needed to keep these compressors running.

How long will an oil-free compressor last? 

While exact timelines are hard to determine as they vary wildly upon several different factors, your oil-free compressor can, in theory, last for years without much maintenance at all.

Beware, however, that the longer you operate an aging oil-free air compressor, the longer it will overall cost versus its oiled counterpart, even despite the oil-free models’ generally lower demands for maintenance in the short term.

This is mitigated slightly with the latest lines of oil-free air compressors as the technology has matured. Also, generally only older ones tend to fall into this disadvantage more often.

Can you lay down an oil-free air compressor?

Considering how it varies from model to model, newer air compressors are generally safe to lay down. You should, however, avoid putting older air compressors at odd angles, as this can result in things like dirt and sludge buildup that can gum the system.

Whenever in doubt, consult your compressor’s user manual and all additional documentation before laying your oil-free air compressor at an irregular angle from the norm.

How do I maintain my oil-less air compressor?

Though oil-free air compressors require a lot less overall maintenance compared to its peers, it is still a machine. Like all machines, your oil-less air compressor needs some TLC and routine maintenance to keep it running smoothly for years.

The best way to ensure the continued reliability of yours is to ensure preventing as much dust and dirt as possible from entering the system.

Alongside that, always be sure to drain the compressor’s tank entirely after each use.

Lastly, routinely check your air compressor’s safety valve and every part of the unit such as hoses, valves, and seals included, for any signs of damage, wear, or tear.
