The Best Water Separators & Filters for Your Air Compressor - EatHappyProject
Air compressors are one of the most important inventions made by humans, and they have revolutionized the operations in the factories, among many other things. Air compressors are found in a lot of appliances like the refrigerator, the air conditioner, etc.
An air conditioner is nothing but a simple device that accumulates air inside the chamber to the point no more air could be fitted inside it. When the air inside the chamber reaches the upper limit, the compressed air is passed through a small opening and used in various ways. The compressor starts to refill the air once the air density inside the chamber reaches its minimum limit.
In various air compressors, the chamber contracts and expands, causing the air inside it to compress. But all in all, it does the same job. When choosing between air compressors, you have two broad options for going for an oiled version or an oil-less version.
The oil-less version is technically more advanced and does the work more efficiently but is very costly. It also produces. A lot of noise might be a problem for you if you work with it for more extended periods. The life of oil-less air compressors is also not much.
On the other hand, Oiled compressors are cheaper than their counterparts, produce less sound, and have a more significant lifespan relatively. But when it comes to performance and advancement, it is eclipsed by its oil-less counterparts.
Air compressors need a lot of maintenance as they are heavy-duty machinery and operate for long periods. These devices’ compressed air is supplied to other tools like jackhammers and painting tools in factories and other places. So, these machines would only be well operating if the compressor is also working well.

Are Water Separators and Air Filters Important for Air Compressors?
Water separators and air filters are very important in an air compressor. It is advised to never use an air compressor without pairing it up with an air compressor and water separators. The compressed air supplied from the air compressor to the tools and other machinery includes many unwanted substances, dust, and moisture.
All these substances are very hazardous for your tools, and they can easily jam or clog them, causing rusts in them, among many other things. So, by not installing an air filter, you make your tools vulnerable to all these hazards that can quickly reduce their life.
A water separator is also a must-have because the filtered water molecules may accumulate and spoil the filter. Therefore, it is essential to let out the water from the system, and a water separator does just that. These cylindrical-shaped devices have used either centrifugal force or filters to filter out the water from the air, and other wastes and have an opening that lets out the water when the tank is filled.
The openings can be either automatic or manual, depending on the water separator you have. Therefore, you must have an air compressor water separator attached to the air compressor to increase the air compressor’s life.
What Are the Effects of Water in Air Compressors and Other Equipment?
The presence of water could lead to many adverse effects on the air compressor and the tools attached to it. Let us look at them one by one.
Eroded Lubrication
Lubrication is one of the essential things in mechanical devices as it reduces corrosion and reduces wear and tear by decreasing friction. The presence of water could result in erosion of lubrication from the moving parts of the equipment, and hence it will increase the wear and tear and act as a catalyst for the rusting process.
Lack of Consistency in Spray Paint Applications
If you are using spray paint to paint a surface, then the presence of water would lead to unevenness in the painting due to blockages and irregularities in supply due to water presence. This would result in the paint being nonuniform and of bad quality. The tones would not be as desired, and the whole job would become one big mess.
Corrosion of Connected Tools
The connected tools with the air compressor are the most vulnerable to moisture and dust-laden unfiltered air. As already discussed, the compressed air would cause the machinery to rust and clog, and hence the life of the tool will be significantly reduced. You will have to incur more costs on repairing or replacing the tools.
As can be observed from the above points, you will have to incur considerable costs to repair the devices than when buying a water separator. Hence a rational and money-saving technique is that you spend some money beforehand on installing the water separator and air filter.
Factors to Consider While Purchasing an Air Filter And Water Separator for Air Compressor
The Type of The Air Compressor
Air compressors come in various types and variants, and you will need to buy a different air filter and water separator for different types of air compressors. So before going ahead with your purchase decision, learn about the air compressor type and find out its model. The manual would help you understand which water separator will suit you the best.
Micron refers to the size of the pores in the air filter. One micron is equal to 0.001 millimeters. Thus, it would help if you also decided from different micron levels. A filter with a higher micron will have more prominent pores, and hence the filtering will not be that effective.
On the other hand, a filter with smaller pores will, though filter out the finest particles, but at the same time will accumulate a lot of waste and hence would need frequent cleaning and even replacements. It would help if you chose whether you want it to refine the minutest particle or work well enough with more prominent pores.
Flow capacity refers to the quantity of air that could easily pass through the air filter. It is measured in Cubic Feet per Minute or CPM. The higher the CPM, the higher will be the flow of air through it. If the airflow is not high, then a larger air filter is required, whereas when the CPM is high, a smaller air filter is required.
Now that you are well versed with the benefits of having a water separator and air filter and aware of the repercussions of not installing it, you should look for the ones that are the best for you and immediately install one if you have not done it already. Here are our top picks for water separators that you can go with if you do not have enough time to search them independently.
