  • It is a multi-purpose water separator.

How Does A Water Separator Work?

As you know, a water separator is used to remove liquid contaminants from air, such as water or oil. The mechanism of a water separator is pretty straightforward, it uses two methods for removing water or oil particles from the compressed air. Depending on these methods, a water separator can be of two types! Each type of water separator will use only one of these two mechanisms, but both of them are quite effective. So here they are—

Centrifugal Separator

The centrifugal water separator works by inducing a spinning or rotary motion to the air while passing through the separator. This vigorous motion stimulates the water or oil particles to speed up & drift to the outer edge.

Once the water or oil particles have drifted to the outer edge, they are deposited inside the water separator which can be drained later. While the water & oil particles are getting separated, the filtered air now can go straight inside the air compressor tank to be utilized whenever needed.

Since the centrifugal force to the liquid particles eventually separates them from the air, this mechanism is called the Centrifugal Separator. You can drain a centrifugal water separator either manually or by installing an automated device for drainage. Overall, the centrifugal water separators are pretty excellent to be used as a water separator.

Coalescing Separator

Unlike the centrifugal separator, a coalescing separator has a built-in filter element that circumvents the liquid or solid particles from the compressed air while moving through the filter. The compressed air is passed through a slender filter that detains the contaminants from entering the air inlet.

As a coalescing separator has no drainage system, you have to clean or replace the filter every once in a while. Some of you may find it hasslesome to do this, because manual draining from centrifugal water separators is far easier. Sometimes you’ll have to get a whole new water separator in case you can’t find the right filter that fits.

As you can see, getting a centrifugal water separator would be much better than getting a coalescing water separator. But if you consider the price range, you surely can give the coalescing water separator a try.

How to Remove the Moisture From Compressed Air?

Compressed air is the fourth energy source for industrial manufacturers. Compressed air has air and vaporized water in it while compressed. The moisture or water should be separated from the compressed air to get the superior working performance of the industrial tools.

10 Best Water Separators For Air Compressor Reviews In 2021 1

There are some strategies/ techniques to remove the moisture or water from the compressed air that is discussed below in detail.

Cool the compressed air:

The first strategy to remove water/moisture from compressed air is cooling down the hot air. This process condensed a significant amount of water from the air.

The condensed air can easily be separated from the air. You can use a heat- exchanger or an aftercooler to do this task.

Use over-compression:

The second strategy is that you can try over-compression pressure to remove water vapor/moisture from the compressed air. In this process, over-compression pressure is used to remove humidity and moisture from the compressed air. 

The separated air allows us to expand to its usual working pressure to do its usual works. This kind of higher- compression is ideal for very small flow rates.

Use membrane drying system:

The next strategy to removing moisture from the compressed air is you can use the membrane drying system. In this system, the gas components process is being used to separate the water from the compressed air.

The separated water collected on the membrane coating fiber, while the filtered air continues flowing through the threads. And this process executed within the cylinder.

Use absorption drying system:

The next strategy that you can follow to remove/ separate moisture/water from compressed air is the absorption drying system. In this chemical system, the moisture gets dried to some liquid/ solid chemical such as sulfuric acid or sodium chloride.

Use adsorption drying system:

The last strategy that you can use to remove water vapor and moisture from the compressed air is the adsorption drying system. In this process, the vaporized water gets dried by flowing over a desiccant.

What to Consider Before Buying a Water Separator for an Air Compressor?

Purchasing the right product can fulfill all your requirements as well as keep you tension free and save your money.

Choosing the right product sometimes becomes very troubling. You don’t need to be panicked. Here in this article, we provide you a proper guideline on what you should consider before purchasing any water separator for an air compressor. So, let’s find out the rest.

Determine the compressor’s operating pressure:

The first thing that you should consider before purchasing a water separator for your air compressor is should determine your compressor’s expected operating pressure. Depending on the pressure you need a basic to the three-stage water separator.

If you know about the expected operating pressure of your compressor, then you can easily choose the suitable water separator for you.

Determine the CFM requirement:

The second thing you should consider before purchasing your water separator is to determine how much CFM your compressor requires. It is an important aspect that you should consider to get superior water separating performance. Determine the accurate CFM that will help you to get a suitable water separator for you. 

Determine the style of the compressor:

The next thing to consider before purchasing a water separator is to determine your compressor’s style. What is the form of your compressor? Is it portable or a stationary compressor?

You should always select a water separator that will be attachable to your compressor’s style. It will help you to get better performance in moisture separation action. Mostly the wall-mounted filters are handy and perfect for you.

Determine the receiver tank size:

Another thing you should consider before buying a water separator is to determine the size of the receiver tank. I am sure that you don’t want to buy a tool that will be bigger or smaller than your required size.

The filter’s tank size depends on how much flows need to be managed. Determining the receiver tank size will help you to get the right product for you. Choosing the best in the market is easy now. 

Frequently Asked Questions

The water separator is indeed a tricky tool to operate, so you need to know all the nuts & bolts about this product. Here we are answering some questions that our readers asked about air compressor water separators-

✅ Why is a water separator mandatory for my air compressor?

Water separators keep my air compressor safe from water vapors and other harmful particles. It removes the moisture problem and extends the life of equipment with great care. 

✅ Is it necessary to drain my air compressor after every single use?

Sure, otherwise the condensed water and other particles will clog into the tank and line. Draining the compressor and proper maintenance will blow out the moisture. 

✅ How can I remove water from compressed air?

A multi-stage filter will do the trick as well. It will remove water and other contamination. You may find other filters with specialized techniques to do the job,too. 

✅ What is the function of an aftercooler for air compressors?

Aftercoolers reduce the heat and cool the air compressor when discharged. It is specialized in removing water vapor or moisture with good care. It condense moisture into liquid and dries them up. 

✅ Why do we need to remove water vapor and moisture from compressed air?

Moisture and water vapor takes place in the air compressor after each use. Temperature is a factor to leave air bubbles in the inner body. These will cause rust and weaken the main structure and cause damage in working performance. It’s a good decision to remove moisture with proper care.
