How Often to Change Dryer Adsorbents

Air dryers are important parts used in industries that need dry air. An air dryer helps get rid of wetness in compressed air. When there's too much dampness, it can start to rust and break things that come after it. The thing that takes away water from compressed air in an air dryer is called a desiccant. It has to be changed every now and then so the air dryer can work its best.

How long a desiccant lasts depends on many things. These include how good it is, how the air dryer works, and how much and how good the compressed air is. Usually, the things that keep the air dry in air dryers need to be changed every 1 to 2 years or when they can't absorb any more moisture.

One way to know if the drying agent needs to be changed is by checking the difference in pressure before and after it. When the stuff that takes away water collects too much water, it can't take any more and the force of air going through it gets weaker. When the air won't flow through the desiccant like it should, the company suggests getting a new one.

You can check if you need to change the drying agent by testing the moisture level of the air after the air dryer. If the air is too wet for the air dryer, it means the desiccant isn't working and needs to be changed.

Remember that how often you need to replace the desiccant depends on what you're using it for and how you're using it. If there is a lot of dirty air in the compressed air, like oil and dust, the desiccant won't work as well and will need to be replaced sooner. Sometimes you may need to change the drying substance more often or add another filter to get rid of dirt before air gets dried.

Apart from changing the drying agent frequently, it is important to regularly take care of the air dryer to make sure it works as best as it can. This means making sure filters are clean, checking valves and fittings, and watching how well the system works. If you take care of the air dryer by getting it checked often, it will last longer and do its job better.

To sum up, air dryers need new desiccants every 1 to 2 years, or when they can't absorb any more moisture. The amount of time the drying agent works well could be different depending on how it's used and the conditions around it. It's necessary to check the air pressure and do a test to see how damp the air is after it goes through the machine that dries it. This will help detect when the drying material needs to be changed. It's important to take care of the air dryer to make sure it works well and lasts a long time.
