Clean air produced by oil-less air compressors is ideal for laboratories, surgeries, food packaging, and beverage dispensing.

3. Cost-Effective:

The oil-less compressor is cost-effective, which means it is inexpensive. If you need a compressor for small projects, you can easily save money by buying an oil-free compressor.

4. Reduced Energy Consumption:

The oil-free compressor does not generate air, which will pollute the atmosphere.

5. Less Weight:

The oil-free compressor is small in size and lightweight. It does not require a lot of people to handle it, and one person is enough to carry it around.

Disadvantages of an Oil-Free Air Compressor

1. Not Durable:

Oil-free air compressors are not very durable, but they are less expensive. Despite this, they get dry due to being pre-lubricated, which shortens their lifespan. Mostly they only last for a maximum of 18-months.

2. Noise Issue:

An oil-free compressor does not get maintenance, so when it starts to dry out, parts of the compressor rub together, creating noise.

Modern compressors are much better than older ones since they do not sound as bad. It is because of soundproofing and dampening techniques used in it.

3. Not Suitable for Heavy-Duty Tasks

The oil-free compressors are not for heavy work, and they are capable of industrial work, and they can only do crafting, inflating bike tires, cutting, etc.

What is an Oil-Lubricated Air Compressor?

An oil-lubricated air compressor is an industrial air compressor that requires oil to function. These air compressors can handle heavy loads, making them dependable and efficient, and these compressors are more durable.

Oil-Free Air Compressors Vs. Oil Air Compressors – Major Difference

Oil-Free Air Compressor Pros and Cons....

Oil-Lubrication – The oil-free air compressor needs no oil lubrication to work, and the compressor is pre-lubricated. It is necessary to change the oil in the oil-lubricated compressor regularly, as it is an oil-lubricated component.

Maintenance – The oil-free compressor does not require regular maintenance, and the oil-lubricated compressor needs regular maintenance.

Air Filtration – The oil-lubricated compressor needs more air filtration to protect the compressor from contamination.

Lifespan – The oil-free air compressor has less lifespan than oil-lubricated air compressors.

Noise level –  The noise level of the oil-free compressors can be louder.

Workload – The oil-lubricated compressor is capable of handling heavy work. So for industrial and heavy-duty tasks, you should go for it.

Oil-Free Air Compressor Life Expectancy

The oil-free air compressors are ideal for price and maintenance. However, the compressor’s lifespan compared to the oil-lubricated compressor is less. The compressor lasts only about 200 hours, or in case the compressor has higher-end units, it lasts 2000 hours.

The new oil-free compressor performs much better than the old oil-free compressors. The compressors can last about 18 months. When a compressor loses its efficiency, most people buy a new one.

How to Maintain an Air Compressor?

User Manual – Maintain the compressor by keeping and reading the manual. It helps the owner to get some information in case of any trouble.

Nuts and Bolts – During operation, the compressor vibrates, which causes the nuts and bolts to loosen. Ensure to check them.

Intake Valves – Intake valves. When air goes through them, dust particles enter. Ensure to clean the intake valves to ensure the compressor does not become a burden.

Hoses – As the hose transfers air from the compressor to the endpoint, it is the most crucial part. The hose needs to be loose and flexible yet tight. Inspect the hoses to maintain the compressor.

Air Filter – Filters remove dust from the air to handle heavy loads. If the air filters are not clean, the compressor will not perform well.

Drain the water from the tank – water in the tank can cause moisture that can cause problems with the compressor’s efficiency. Also, moisture can enter the other parts of the compressor, which can cause rusting.

Clean fuel tank – Annually clean the fuel tank as it can become poisonous if you do not clean it. The particles can lead to being toxic over time.

Verify the power-off system – When the power supply trips or the machine gets too hot, the automatic power-off feature automatically helps the device shut down. Ensure that the button is in good working condition to save the compressor.
