Do I Need an Air Oil Separator




An air oil separator is a device that helps to remove oil from air. It is often used in compressed air systems to help keep the compressor and other components clean. Air oil separators can be either internal or external to the compressor.

If you own an air compressor, then you might be wondering if you need an air oil separator. The short answer is that it depends on the type of air compressor you have and how often you use it. If you have a rotary screw air compressor, then it is recommended that you use an air oil separator.

This is because these types of compressors tend to produce a lot of oil mist and condensation, which can lead to problems with your air quality if not properly treated.

What is the Benefit of an Air Oil Separator?

An air oil separator is a device that helps to remove oil from compressed air. It is often used in compressor systems to help improve the quality of the air being delivered and to reduce maintenance costs. The benefits of using an air oil separator include:

1. Reduced Oil Consumption: By removing oil from the compressed air, there is less chance of it contaminating downstream equipment or processes. This can lead to reduced oil consumption and fewer lubrication issues. 2. Improved Air Quality: With less oil in the system, the quality of the compressed air delivered is improved.

This can be beneficial for applications where cleanliness is important, such as food and beverage processing or semiconductor manufacturing. 3. Reduced Maintenance Costs: Removing oil from the system can extend the life of downstream equipment by preventing contamination and build-up of deposits on critical components. This can lead to reduced maintenance costs over time.

What’S the Purpose of an Oil Separator?

An oil separator is a device used to separate oil and water. Oil separators are used in a variety of industries, including automotive, manufacturing, and environmental. There are three main types of oil separators: gravity, coalescing, and centrifugal.

Gravity oil separators work by using the difference in density between oil and water to separate the two fluids. The oily water mixture is placed in a chamber where it settles into two layers: an upper layer of light oils and a lower layer of heavier water. A series of baffles or plates inside the chamber help to keep the two layers from mixing back together.

The lighter oils are then skimmed off the top while the heavier water remains at the bottom. Coalescing oil separators work similarly to gravity separators but use finer filters to remove smaller particles of oil from the water. Coalescingseparators typically have multiple stages with each stage removing progressively smaller particles of oil.

These devices are often used when very high purity levels are required such as in food processing or pharmaceuticals manufacturing. Centrifugal oil separators utilize centrifugal force to separate oils and waters. In this type of device, an oily water mixture is placed in a spinning chamber where centrifugal force pulls the heavier waters towards the walls while the lighter oils remain in suspension near the center.

Will Air Oil Separator Void Warranty?

If your car is still under warranty, then you should check with your dealership to see if an air oil separator will void the warranty. Many dealerships are now okay with aftermarket parts as long as they don’t affect the engine or other systems in the car. However, it’s always best to check before you make any modifications to your car.

Is an Air Oil Separator the Same As a Catch Can?

An air oil separator (AOS) is a device that separates oil and air. The separated oil is then collected in a catch can. An AOS is used to prevent oil from entering the engine’s combustion chamber, where it can cause fouling and damage.

An AOS typically consists of a housing with an inlet and outlet, and a baffle or filter that separates the oil and air. The separated oil is collected in the bottom of the housing, while theair passes through the baffle and out the outlet. While an AOS performs the same function as a catch can, there are some important differences between the two devices.

First, an AOS is designed to be installed inline with the engine’s crankcase ventilation system, while a catch can is not. This means that an AOS will take up less space than a catch can, as it does not require its own dedicated hose routing. Second, an AOS typically has a much higher capacity than a catch can – often several times greater.

This means that it can collect more oil before needing to be emptied, making it more convenient to use. So, while an air oil separator and catch can serve similar purposes, they are not interchangeable – each has its own advantages and disadvantages that should be considered when choosing which one to use.

How an Air Oil Separator Works and Why You Need One!

Best Air Oil Separator

An air oil separator is a device used to separate lubricating oil and compressed air in an engine. The separator ensures that the engine oil is not contaminated by the combustion process, while also providing a source of clean, dry air for the engine. There are many different types of air oil separators on the market, but they all work towards the same goal: keeping your engine running smoothly and efficiently.

Air Oil Separator Benefits

An air oil separator is a device that helps to remove oil and other contaminants from compressed air. There are many benefits to using an air oil separator, including: 1. Increased Air Quality – By removing oil and other contaminants from the air, the quality of the air is improved.

This can lead to better work conditions and fewer health risks for those who are exposed to the air. 2. Improved Airflow – When contaminants are removed from the air, airflow is increased. This leads to better work conditions and increased efficiency.

3. Reduced Maintenance Costs – By removing contaminants from the air, there is less need for maintenance and repairs. This can save money over time on both labour and parts costs. 4. Environmentally Friendly – Removing oil and other pollutants from compressed air reduces emissions and helps protect the environment.

Air Oil Separator Vs Catch Can

An air oil separator, also called an AOS, is a device fitted to an internal combustion engine that separates out the oil and other contaminants from the air before it enters the engine. This helps to keep the engine clean and running efficiently. A catch can is a container that catches and holds liquids or vapors released from another object.

Catch cans are often used to collect excess oil and other fluids that may be present in the engine bay of a vehicle.

Iag Air Oil Separator

An IAG Air Oil Separator is a performance upgrade that improves the function of your engine by separating oil and air in the crankcase. This allows for cleaner, more efficient combustion and can increase power output. The IAG Air Oil Separator also helps to reduce emissions from your engine.


If you own a small plane, the answer to whether you need an air oil separator is most likely no. The main purpose of an air oil separator is to keep the engine oil clean. However, if your plane does not have an engine-driven vacuum pump, then your engine is not subject to the harmful effects of oil contamination.
