I came to know about the function of the semi-auto drain from the user guide, which is included in the compressor. The drain runs auto and manual both ways; for example, when I try to apply pressure to the bowl, the drain keeps holding the moisture stuffing and waits for you to discharge it manually. But, when there is no pressure, the bowl itself opens and discharges the stuffed moisture!

Now, come to how much pressure is good to apply for the best result; the highest pressure input for this air compressor is 175 PSI, where the maximum output force should be 145 PSI.

Air Compressor Water Separator Buying Guides

Many companies make vigorous water separators. You have to be smart while buying one. Let us have a look at what to keep in mind while buying a water separator. Never overlook them. These things are more important than you think.

The Bowl

Look out for the quality of the poly bowl where the extra water and oil can be trapped. In the water separator, there is a bowl. Make sure it is made of polycarbonate or metal.

The Quality of The Drain

A drain is the most important part of a water separator. There are automatic and manual drains inside the Compressor Filters. An auto drain helps it to lower the working pressure by doing the clearing process by itself.

Glass Sealed

To examine the moisture level, it is good to have a glass sealed water separator. You can check the condition through the glass material and take action easily.

Pressure Load Capacity and Input-Output Port

Check the pressure loading capacity of the water separator according to your air compressor load. The water separator must cope up with the load of your air compressor. Also, check out if the input and output port are efficient enough to work out with the air compressor. Most of the best water separators are convenient to work with every type of air tool.

Frequently Asked Questions

In this section, I am going to answer some of the most frequently asked questions about water separator for the air compressor to help you get rid of any kind of confusion.

Q: How does a water separator for an air compressor work?

Ans: The water separator collects the untreated residues. The separating process is done by depressurization.

The depressurized items then go to another part where there is media made of a fiber that absorbs oil and let the water pass. Going into the next part, the fiber floats and the weight of oil make the filter sink and the clean filter touches the water.

The rest filtered ingredients then flow to the other part, which has activated carbon to absorb all the remaining oil. Finally, the clean water also drops out by the output port and thus the water vapor, oil and dirt get filtered out of the air compressor.

Q: Does my air compressor need a water separator?

Ans: While the compression process occurs, the contamination such as hot oil, water vapor, and remaining dirt gets mixed. It makes a mess that disturbs the air compressing process and destroys the compressor. So, you need a water separator to maintain the workability and durability of your air compressor.

Q: Where do you put the water separator on an air compressor?

Ans: You must mount your water separator minimum 20 feet away from the compressor. This distance allows the air to have time to cool down and drop the moisture. The more time it gets, the more condensation can be filtered from the air compressor tunnel.

If you mount it right next to your compressor, there are chances of remaining the vapor inside the compressor as it gets little time to cool down and drop as water.

Q: How often do I need to change the filter?

Ans: Usually, it does not need to be changed frequently. It depends upon your use and the humidity of the place you use it in. However, when you see any kind of breakage problem, distortion or anything like a ‘fish-eye’ lens, you may need to change the filter then.
