The Benefits of Oil-Free Compressed Air

The Benefits of Oil-Free Compressed Air
Oil-free, compressed air provides various benefits that its oil-laden counterpart cannot

You can use an air compressor in a variety of places, such as your home, garage, or business. These machines can inflate tires and supply air to machinery. There is a variety of types and sizes of air compressors available, but if you’re looking to reduce the risk of contamination, minimize operating costs, and reduce your carbon footprint, consider using an oil-free compressor for your next job.

What is Oil-Free Compressed Air?

In a traditional air compressor, the air comes out thanks to a turning piston inside the compression chamber. This chamber makes an oil-lubricated air compressor different from one that’s free of oil. The piston needs lubrication, or oil, for the compressor to operate. Oil-free compressors don’t need oil because the cylinders are already pre-lubricated, and a Teflon coating protects them and allows them to remain permanently lubricated.

How it Works

The oil-free compressor brings in outside air through an unloader valve. From there, the air passes through an air filter to make sure it’s clean. In other words, the filter limits dirt and debris damage to the compressor. From there, the unloader valve opens to let the compressor pump air into the chamber. When the valve closes, the compressor starts running. When the compressor is running, it usually cannot take in any more air.

Less Maintenance

A traditional air compressor requires regular oil changes, the frequency of which depends on the compressor’s use and design. After you change the oil, you have to dispose of it, which can take time and money. You also need air and oil separator elements and filtration to remove oil aerosols. With an oil-free air compressor, you don’t have to worry about any of these. To extend the life of your oil-free unit, however, be sure to drain the air compressor tank completely after each use. The tank holds water vapor that condenses and collects inside.

Lighter to Lift

Oil-free air compressors have fewer parts inside. As a result, they weigh much less than traditional ones. An oil-free compressor can weigh as little as 20 pounds, whereas a traditional one can weigh several hundred pounds. This makes the oil-free option a solid choice for smaller or medium-sized jobs at home. You can use them to fill tires, provide air to smaller machines such as jackhammers, or to spray paint an area.

Lower Costs

You can save money with oil-free compressors. They typically cost less, thanks to their simple design, and they are also built to last. There are fewer parts in the machine, so there will be fewer repair or replacement requirements. Some oil-free compressors have regulators, which let you use energy only when you need it. These automatic shut-off switches turn off the compressor when it’s not in use. This helps you to save energy and fuel costs.

Multiple Uses

Unlike the traditional compressors, the oil-free ones can operate in more than one direction. Because of their smaller size and lighter weight, you can transport them easily and move them horizontally or vertically, depending on your task. And, of course, since they’re oil-free, there are no leakage problems when you tilt them in different directions.

Faster Starts

An oil-based compressor usually needs more amps to begin working, so if you were planning to use one in a cold garage, it would probably be slow to start. That’s because oil is more viscous, thus harder to move, at colder temperatures. Oil-free compressors can start much faster, no matter what the temperature is.

Environmentally Friendly

Eliminating oil from the air compressor helps to keep the environment safe because this type of compressor does not release contaminants into the air. In addition, certain tasks might require clean and oil-free air and, therefore, cannot encounter oil contamination. Oil-free air compressors provide that peace of mind. You can use oil-free compressors for tasks that involve food, paper, and medicine.

No matter what type of task you need to complete, when you use oil-free compressed air, you’re helping to save the environment and reduce costs. Air purity is also vital for some tasks, and even the smallest drop of oil can cause damage. Make sure you know what type of job you need the compressor for because you may be able to benefit from renting an oil-free air compressor.
