An air compressor, if used for some days, can get water and oils inside it. It is dangerous for the compressor as the water can potentially cause corrosion. It is also capable of ruining the paint job.

Best Air Compressor Filter Dryer's Buying Guide
With all the excitement as you are planning to buy an ideal air filter for your air compressor, you should note that there are some certain points to check while doing it. Getting the wrong air compressor dryer is dangerous.
It is because the main role of an air filter is to purify the water, something that ensures the safety of your compressor. Without proper performance, your compressor is not only vulnerable to harmful debris, but also, it can damage the application too.
With that being said, let's look at the necessary factors to look into your air compressor water trap.
To function properly and cope with the air compressor's capability, your air filter should have an inlet pressure that goes with the maximum pressure rating of the compressor. For most cases, the ideal rating will be around 140 PSI or more.
A much pressure rating offers better performance. Its regulator pressure should also be between 0-145 PSI to work with any pressure rating that you want.
Oil Aerosol Removal
If your air filter cannot remove all the oil aerosol inside the compressed air, it is no good. Even more than water, oil is highly problematic to have in your compressor. They damage the interior parts, leaving dirty air to be used.
That is why you got to make sure that your air filter has proper oil filtration capability. Normally, a water trap that has a filtration limit of 10 microns can do the job. The lesser this state is, the better.
A larger tank is especially necessary if we are talking about a large amount of air or an air compressor that gets more dust than average. Small tanks cannot store much dirt, so it is not capable of filtering completely.
You can get two types of drain systems, the manual ones and the automatic ones. Well, manual ones don't have any pros of their own. You just got to take out the dirt yourself.
Meanwhile, an automatic one can save you the hassle by doing the releasing process by itself. That is why automatic drains are much better.
When you think about it, an air filter may need to go through harsh weather and environments. Because of that, you should choose your air dryer that is made of any hard material. It should also have high heat and cold resistance.
In case it is your first time getting an air filter, research about how to use it with an air compressor. Keep in mind that without a proper setup, the filter may not show the maximum performance. Also, you can ask your manufacturers for help.
Most items like a water trap come with instruction manuals, so do not neglect reading it thoroughly. If it has manual drainage, be sure to remember to release the dirt routinely. Otherwise, you may end up in frustration.
